CHINESE WOOD OIL = TUNG OIL

CAS Number: 8001-20-5
EC Number: 232-272-3

Chinese wood oil or Tung oil is a drying oil obtained by pressing the seed from the nut of the tung tree (Vernicia fordii). 
Chinese wood oil and Chinese wood oil's use are believed to have originated in ancient China and appear in the writings of Confucius from about 400 BC.
Chinese wood oil hardens upon exposure to air (through polymerization), and the resulting coating is transparent and has a deep, almost wet look.  

Related drying oils include linseed, safflower, poppy, and soybean oils. 
Raw Chinese wood oil tends to dry to a fine, wrinkled finish (the English name for this is gas checking); this property was used to make wrinkle finishes, usually by adding excess cobalt drier. 
To prevent wrinkling, Chinese wood oil is heated to gas-proof it (also known as "boiled").
Pure Chinese wood oil in non-flammable & can be regarded as non-toxic. 

Although Chinese wood oil smells somewhat like a salad oil Chinese wood oil is not to be used for cooking or salad dressing. 
Due to the slight exothermic property of the oil while curing (a commonplace feature of drying oils), there is a marginal risk that balled, oily rags may spontaneously combust - spread application rags out to dry. 
Pure Chinese Wood Oil is a natural, non-toxic wood care finish. 
In Chinese Wood Oil's pure form, Chinese Wood Oil contains no dryers, additives or solvents and is completely safe and healthy to work with. 

Chinese Wood Oil wood finish is also known as China Wood Oil, since Chinese Wood Oil’s pressed from the seed of the Chinese Tung Nut Tree. 
Chinese Wood Oil is characterized by a distinct nutty small. 
The smell wears off around a few weeks after applying Chinese Wood Oil. 
Whether Chinese Wood Oil’s furniture in your house or a gate or other wooden objects in your garden, the smell will soon disappear.

Chinese Wood Oil wood finish leaves a water resistant, hard wearing, long lasting barrier
Pure Chinese Wood Oil becomes hard upon exposure to air and leaves a hard coat with elastic properties. 
As a result, the Chinese Wood Oil coat will expand and contract with age and changing temperature. 
This type of coat is the best hard wearing protection possible for wooden furniture and other wooden surfaces, both in your house and garden. 

Moreover, the matt transparent finish of Chinese Wood Oil is water resistant and has a slight golden tint.
Chinese wood oil or tung oil is extracted from the seeds of the tung tree. 
Thanks to Chinese wood oil's extremely small molecules, Chinese wood oil has excellent depth penetration properties and has long been used to protect wood against moisture penetration and cracking.
Chinese Wood Oil is a blend of the finest natural plant oils. 

Designed to offer the greatest penetration, efficient coverage and toughest protection for all timber.
Chinese wood oil with high dryness factor, based on Chinese ”heavy tree oil” combined with a fatty alkyd and linseed oil. 
Chinese wood oil has been used for thousands of years to protect wood from the penetration of moisture. 
The share of Chinese oil is 85 % of the share of Chinese wood oil. 

The Chinese oil differs from ”conventional” oil through its smaller molecular size gives it extremely deep penetration properties. Also mitigate cracking, blue quenching and mould.
Chinese wood oil is a type of wood finishing product that is derived from the pressed nut of the tung tree. 
Chinese wood oil is drying oil that is similar to linseed, safflower, poppy, and soybean oil. 

Drying oils are perfect for wooden objects, since Chinese wood oil dries to a clear film once Chinese wood oil has made contact with the air. 
Pure Chinese wood oil and Chinese wood oil finishes are two distinct products that should not be confused with one another.
Chinese wood oil, also known as Tung Oil, Lumbang oil, Noix d’abrasin (fr.) or simply wood oil, is made from the seed kernels of the Tung tree (Aleurites fordii and Aleurites montana, family Euphorbiaceae).
Chinese wood oil, also called wood oil, pale-yellow, pungent drying oil obtained from the seeds of the tung tree. 

On long standing or on heating, Chinese wood oil polymerizes to a hard, waterproof gel that is highly resistant to acids and alkalies.
Chinese wood oil is produced chiefly in China from the tung tree (q.v.; Aleurites fordii).
Tung oil or China wood oil is obtained by pressing the seed from the nut of the tung tree (Vernicia fordii). 
Chinese wood oil hardens upon exposure to air, and the resulting coating is transparent and has a deep, almost wet look. 

Used mostly for finishing/protecting wood, after numerous coats the finish can even look plastic-like.
Chinese wood oil and Chinese wood oil's use are believed to have originated in ancient China and appear in the writings of Confucius from about 400 B.C. 
Raw Chinese wood oil tends to dry to a fine wrinkled finish to stop this, Chinese wood oil is heated, also known as “boiled”.
The name is often used by paint and varnish manufacturers as a generic name for any wood finishing product that contains the real Chinese wood oil and/or provides a finish that resembles the finish obtained with Chinese wood oil.

Chinese wood oil tree originates in southern China and was cultivated there for Chinese wood oil, but the date of cultivation remains unknown. 
During the Song Dynasty, Chinese wood oil was used for waterproofing on ships. 
The earliest references for Chinese use of Chinese wood oil is in the writings of Confucius around 500 to 400 BC. 
The Chinese have used Chinese wood oil, also known as China wood oil, for at least 2500 years for building waterproof boats and paper parasols, wood finishing, wood waterproofing, caulking, inks and paints. 

Marco Polo wrote in the 13th century “The Chinese take some lime and chopped hemp, and these they knead together with a certain wood oil; and when the three are thoroughly amalgamated they hold like any glue, and with this mixture they paint their ships”.
Chinese wood oil (also called Tung oil) contains a conjugated triene acid, α-eleostearic acid at 69%. 
Chinese wood oil dries quicker than linseed with less oxygen incorporation. 

Chinese wood oil is mainly exported from China to other countries in the Far East or the United States. 
Nonfood uses include paints, coatings, varnishes, resins, and sealers. 
Of especial note is Chinese wood oil's use as coatings for food, drink, or medicine containers and as insulation for wires and metallic surfaces in communication hardware.
Chinese wood oils produced from the seeds of the tung tree (also known as the China wood oil tree) [Vernicia fordii (Hemsl.) and Vernicia montana (Lour.)] (previously Aleurites fordii and Aleurites montana) (Govaerts, 1966) occupy an important niche in the industrial vegetable oils market. 

The trees likely originated in China and have been grown and cultivated for oil production there for thousands of years; descriptions of tung oil use appear in the writings of Confucius from about 400 BC.
For a more comprehensive description of the industrial development and history of tung production in China. 
China still accounts for at least 70% of global tung oil production annually, but over time production has spread to various other countries.
This crop was established in the United States nearly a century ago, and the supply of Chinese wood oil quickly rose to fill the demand for high-quality fast-drying oils for use in the manufacturing of paints, varnishes, inks, linoleum, and numerous other products. 

In recent years, Chinese wood oil has been used in synthesis schemes for the production of modern high-value/high-performance materials such as specialized resins and biodiesel. 
Recent advances in biochemistry and molecular biology have provided the means to dissect the tung oil biosynthetic pathway, an important step toward the long-term goal of engineering tung-like oils in the seeds of other oilseed species. 
The progression of tung tree propagation and oil utilization along this historical timeline, from the primitive physical processing of Chinese wood oil from a few trees in 1900s Florida to commodity level production and utilization of the oil in sophisticated organic synthesis designs and molecular breeding programs is an interesting vignette in the history of American agricultural science. 

In this review, we will present a brief history of the tung industry in the United States, describe some of the modern uses of Chinese wood oil in industrial processes, and summarize the current status of genetic and biochemical analysis of the genes and enzymes in the Chinese wood oil biosynthetic pathway.
The seeds of the Tung tree that are reminiscent of enormous chestnuts contain the valuable Chinese wood oil. 
From these seeds the Chinese wood oil or Tung oil is won with which wooden objects can be finished and protected beautifully both inside and outside, and a silk-gloss protective film For centuries Chinese wood oil, also known as Tung oil, is used for making underneath other paint and ink. 

However, the most important application of Chinese wood oil is finishing all sorts of wooden objects. 
Chinese wood oil is extracted from the seeds of the Tung tree and professionals use Tung oil mainly to finish wooden objects. 
Chinese wood oil is therefore seen as the best natural oil finish that exists.
Pure or raw wood oil is a finishing product that gives a strong, flexible and water-repellent surface. 

Chinese wood oil is a drying oil just like linseed oil, sunflower oil, walnut oil and so on. 
Chinese wood oil is not only used in China for finishing wood but also for finishing stone. 
Moreover, Chinese wood oil is seen as the best protection for wooden ships. 
According to tradition, Marco Polo was the one who introduced Chinese wood oil in the Western countries although Chinese wood oil was only used to a limited extent until the 19th century. 

In the 19th century, however, Chinese wood oil was "discovered" by paint and varnish makers as a very valuable ingredient for their products and today the quality of a product is also determined based on the percentage of Chinese wood oil present in that product. 
In the meantime, Chinese wood oil has been favored by many because Chinese wood oil dries faster, is stronger and does not get dark with time.
Pure Chinese wood oil is water resistant, penetrates well, is elastic and usually does not tear. 

Chinese wood oil quickly gives a firm layer thickness, protects the wood perfectly and gives a transparent, matte finish. 
You store Chinese wood oil best in a sealed bottle with as little oxygen as possible (full bottles). 
Raw Chinese wood oil smells slightly to nuts, is light yellow in color and contains no thinners or drought.
Chinese wood oil is also known as China wood oil, and as with most other oils dries with exposure to air. 

Chinese wood oil’s a plastic like, clear coating that is used away from wood finishing in printing inks and oil paints.
When used on guitars, Chinese wood oil leaves a wet wood look, that has a slightly golden tint.
Often considered to be the finest and most natural finish for wood, Chinese wood oil does require a different application process.
Chinese wood oil is a hard drying wood oil that provides a lustrous and beautiful finish. 

Chinese wood oil resists marring, penetrates well, and is environmentally friendly. 
Chinese wood oil is 100% pure and of the highest quality you’ll find. 
Chinese wood oil’s all-natural, food safe, and creates a matte finish. 
FDA approved for food contact.

Pure Chinese wood oil comes from the cold pressing of the seeds or nuts of the Tung tree. T
Tung trees mainly grow in the mountainous regions of China away from industrialization and pollution. 
Climate, soil and air quality are essential for high-quality oil. 
Our 100% Pure Chinese Tung Oil or China wood oil is an all-natural finish manufactured by pressing the tung nut, no petroleum distillates or other additives - just Pure Chinese wood oil. 

All Pure Chinese wood oils are not the same. 
Chinese Pure Tung Oil is available in 3 grades. 
A better quality Pure Chinese Tung Oil will offer superior color, faster drying, and a long term elastic finish. 
Elasticity is an important factor as the oil must continue to flex with the expansion and contraction of the substrate on which it is applied.

For new wood floors and refinishing wood floors, applications of Pure Chinese wood oil must be thinned. 
The color of wood finished with Pure Chinese wood oil will vary based on the wood species. 
Dark Chinese wood oil is also available. 
Pure Chinese wood oil is easy to identify because it contains no solvents.

That may be a good thing in terms of limiting your exposure to VOCs, but applying Chinese wood oil is an exacting, drawn-out process.
You have to wait at least two to three days for each coat to harden. 
And Chinese wood oil takes five to seven coats to get a protective film. 
Rushing the process, or applying too thick a coat, causes wrinkling, which has to be sanded off.

Regular reapplication is a must—“once a week for a month, once a month for a year, once a year ever after,” as the saying goes. 
The results can be gorgeous, as long as you have the necessary patience.
Originating from China and South America, Chinese wood oil—an extract from tung-tree nuts—is a natural drying oil that coats your fine wood furnishings with a transparent, wet finish. 
Chinese wood oil enhances the color of your wood, offers excellent protection and is eco-friendly.

Chinese wood oil is also known as China wood oil, and as with most other oils dries with exposure to air. 
Chinese wood oil’s a plastic like, clear coating that is used away from wood finishing in printing inks and oil paints.
When used on guitars, Chinese wood oil leaves a wet wood look, that has a slightly golden tint.
Often considered to be the finest and most natural finish for wood, Chinese wood oil does require a different application process.

Chinese wood oil is a plant-based oil used as a wood finish. 
Chinese wood oil is clear, quick-drying, and penetrates the grain to enhance and protect the wood. 
Chinese wood oil’s one of the oldest and most popular wood finishes in the world and is derived from the seeds of the tung tree in Eastern Asia.
Chinese wood oil has become a staple among fine furniture craftsmen in the United States and beyond. 

Chinese wood oil is eco-friendly, non-toxic, and food-safe.
Chinese wood oil is derived from pressing the seeds of the tung tree, which is native to Eastern Asia. 
Chinese wood oil has been cultivated and used in China as a wood finish for at least 2,500 years.
Similarly to linseed oil, it is difficult to find furniture that is made with raw or 100% pure Chinese wood oil. 

There are many reasons a craftsman might consider using Chinese wood oil to finish wood furniture. 
Chinese wood oil’s all natural, non-toxic, and eco-friendly, and Chinese wood oil doesn’t yellow as much over time as common finishes like linseed oil, nitrocellulose lacquer, or varnishes like polyurethane.
Chinese wood oil, also known as Tung Oil, Lumbang oil, Noix d’abrasin (fr.) or simply wood oil, is made from the seed kernels of the Tung tree (Aleurites fordii and Aleurites montana, family Euphorbiaceae). 
The A. fordii tree grows well in cooler climates, but can survive up to sub-tropical climates. 

A. montana is restricted to a more tropical climate. 
China, Argentina, Paraguay, Brazil and the USA are all major producers of Chinese wood oil.
Chinese wood oil has a proven history in exterior applications, both above and below the soil level. 
Though the dried oil is relatively hard, the finish Chinese wood oil provides is not the most durable. 
Chinese wood oil is usually chosen for Chinese wood oil's aesthetic appeal rather than Chinese wood oil's wearability.

In Chinese wood oil's pure form, tung oil is a non-toxic finish that is ideal for surfaces that are expected to come into contact with food. 
This includes wood cutting boards, salad bowls, salt and pepper mills and any other project imagineable.
Chinese wood oil produces a mildly disagreeable odor for a few days after it is applied. 
This odor lessens with time, however some find that Chinese wood oil continues for quite some time afterwards. 

If the Chinese wood oil is to be coated with some other finish such as wax, shellac, lacquer or polyeurethane, this smell is no longer noticeable.
Chinese wood oil takes time to dry. 
Today’s high-tech woodworker is often in a hurry, but true tung oil takes its time to cure.
Pure Chinese wood oil has relatively poor penetration, and scratches that penetrate the finish can expose the bare wood beneath. 
This can be compensated for by adding up to 50% turpentine as a thinning agent to improve penetration on the first coat only. 

Subsequent coats should be done with un-thinned tung oil.
Pure Chinese wood oil is difficult to store. 
Depending on temperature, and exposure to light, the surface of Chinese wood oil in the container will start to form a film or there will be gummy deposits around the container’s edges. 
Once these symptoms appear, the entire container must be discarded, since Chinese wood oil will no longer be able to cure properly if applied.

Pure Chinese wood oil is extracted from the seed of the tung tree, which is native to China and a few other Asian countries. 
Chinese wood oil is considered to be an environmentally friendly wood finish as Chinese wood oil doesn’t contain any other ingredients or manufacturing processes. 
Chinese wood oil is also less known as China wood oil and Chinese wood oil's use is thought to have originated in China as far back as 400 B.C.
Chinese wood oil’s worth noting that whereas some Chinese wood oils are pure, some brands of ‘Chinese wood oil’ do contain additives and other ingredients to assist with application and drying.

THINNING:  
Can be thinned with Citrus Solvent for an all-natural finish. 
Can also be thinned with Mineral Spirits, Odorless Mineral Spirits, Paint thinner, and Odorless Paint thinner. 
Do not use a mineral spirit or odorless mineral spirit marketed as “green”, “eco-friendly”, or similar verbiage. 
These do not mix with the Chinese wood oil and will create adverse effects on your finish. 
Typically these thinners have a milky appearance in the bottle rather than clear.

TEMPERATURE:  
Should remain above freezing during and after application for a period of 10 to 15 days. 
If freezing temperatures do occur it is possible for the fat in the oil to rise out of Chinese wood oil and deposit on the surface. 
The warmer the temperature the faster the oil will cure. 
However direct sunlight baking a surface after a “fresh” application can quickly polymerize Chinese wood oil and result in a dry rubbery frosted appearance or a distinctly more glossy finish than the surrounding area.

Chinese wood oil, also known as tung oil, was first used 2,500 years ago. 
Chinese wood oil is made with seeds from tung tree nuts. 
When hardened, Chinese wood oil becomes strong and does a good job of protecting surfaces.
Confucius wrote about Chinese wood oil in 400 BC. 

You might think the popularity the ancient oil would have waned by now, but it hasn’t.
Chinese wood oil is made by pressing the seeds of the tung tree which is native to Vietnam, Myanmar and Southern China. 
Chinese wood oil has been utilized for centuries as a natural wood protectant and was historically used by the Chinese to help preserve and waterproof ships and boats by heating tung oil, chopped hemp, gum rosin and lime.
Chinese wood oil is a natural drying oil that hardens to a film when exposed to air. 

Chinese wood oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree (Vernicia fordii). 
As a drying oil, Chinese wood oil hardens (dries) upon exposure to air. 
The resulting coating is transparent and plastic-like; a property which is exploited in most of Chinese wood oil's applications such as wood finishing, as well as in the composition of oil paints and printing inks.
Chinese wood oil, also known as Chinese wood oil, is the oil extracted from a walnut-like nut grown in China, Argentina and the USA. 
Chinese wood oil was commonly used to seal wooden boats, which explains Chinese wood oil's desirable properties such as hardness, water-resistance and a wide chemical resistance. 

Combined with the softer more flexible linseed oil, Chinese wood oil creates a tough and durable coating.
Chinese wood oil is a traditional oil that contains genuine Chinese wood oil, a natural wood oil. 
Chinese wood oil is formulated to penetrate deeply into timber, resulting in a natural matt finish that can be burnished or waxed if desired. 
Chinese wood oil is quick and easy to apply, resistant to water and spills, and easily maintained.

USES and APPLICATIONS of CHINESE WOOD OIL:
-Chinese wood oil is used mostly for finishing and protecting wood, after numerous coats, the finish can even look plastic-like.
-'Chinese wood oil' is often used by paint and varnish manufacturers as a generic name for any wood-finishing product that contains the real Chinese wood oil or provides a finish that resembles the finish obtained with tung oil.

-Wood finishing:
Chinese wood oil is very popular today because of two properties: first, Chinese wood oil is a naturally derived substance. 
Second, after Chinese wood oil cures (5 to 30 days, weather/temperature related), the result is a very hard and easily repaired finish, so Chinese wood oil is used on boat decks and now on floors. 
Chinese wood oil is often diluted with hydrocarbon thinner so Chinese wood oil's viscosity is very low and enables Chinese wood oil to penetrate the finest grain woods. 

This thinning vehicle evaporates within 15 to 20 minutes. 
When applied in many fine/thinner coats over wood, tung oil slowly cures to a matte/light satin look with slight golden tint. 
Chinese wood oil resists water better than any other pure oil finish and does not darken noticeably with age. 
Chinese wood oil is claimed to be less susceptible to mould than linseed oil. 
Chinese wood oil is considered safe to be used on sculptures made near waterways.

-Since Chinese wood oil has become popular as an environmentally friendly wood finish, some products labelled as "Chinese wood oil" are actually blends containing other oils, varnishes, solvents, or chemical driers, and may even contain no tung oil at all Products labeled. 
Danish oil may be Chinese wood oil or they may be polymerized linseed oil. 
The product packaging will usually clearly state if it is pure Chinese wood oil.

-Heating Chinese wood oil to about 500 °F (260 °C) in an oxygen-free environment will substantially increase the viscosity and film-forming quality of the product. 
Most polymerized Chinese wood oils are sold mixed with mineral spirits to make them easier to work with. 
Limonene and D-limonene are less toxic alternatives for mineral spirits.

-Oil-paper umbrella:
The oil-paper umbrella is the traditional umbrella used in China, Japan, and other countries in the sinosphere, and was brought to Western countries through the Silk Road. 
Chinese wood oil is the "oil" mentioned in the oil-paper umbrella, which is used to protect the paper from getting wet, and to make the umbrella waterproof.

-The traditional technique for applying pure Chinese wood oil is to dilute the oil 1:1 with solvent, then apply a succession of very thin films with a soft, lint-free cloth such as tee-shirt cotton. 
Dilutents range from traditional spirits of turpentine to any of the new citrus-based thinners to naphtha. 
The choice of thinner should be guided by how fast the coating needs to set. 
Naphtha works well in spray-on applications in well-ventilated studios. 
Primary coats may be laid down at a 1:1 oil-to-thinner ratio, and successive layers, if not absorbed into the wood, at higher solvent to oil concentrations. 
This technique brings out the deepest color of the wood while maintaining a matte finish.

-Chinese wood oil finishes that start with polymerized oils or Chinese wood oil preparations are best applied in the fat over lean principle: thinned pure oil is applied to deeply penetrate the surface, to fill pores. 
Straight oil is then applied moderately to adhere to the surface and provide a good base for the thick gloss layers. 
The polymerized oil is then applied thickly as a single layer, allowed to fully dry, buffed smooth with very fine sandpaper and 0000 steel wool. 
The surface is wiped clean with a moistened rag and allowed to dry. 
A final coat is applied fairly thickly (Chinese wood oil will smooth itself into a glass-like coating) and allowed to dry for two to three days. 
Rags soaked with Chinese wood oil can spontaneously combust.

-Chinese wood oil is a tree nut oil which polymerises naturally and cures to a tough, buffable, water resistant, beautiful finish which patinates better than skin finishes.  
Pure Chinese wood oil is safe for use on wooden toys (EN71 compliant) and kitchen woodwork which contacts foodstuffs.
-Chinese wood oil is suited to wooden floors, interior and exterior woodwork including decks, window and other wooden joinery, kitchen tables and bench tops, chopping boards, concrete, stone and terracotta surfaces, rammed earth floors and children's toys. 

-Chinese wood oil is a preferred finish for gun stocks and didgeridoo.
-Chinese wood oil is often used as a figure enhancing sealer under other top finishes such as shellacs and varnishes. 
-Pure Chinese wood oil is also the preferred product to seal beehives and treat wood in horse stables.  
In these instances, where there will be intimate contact with animals and insects, Pure Chinese wood oil used neat is recommended.

-Pure Chinese wood oil will, in common with all oil finishes, darken the wood somewhat.
-When considered for use on floors the floor finishing trades are accustomed to getting floor polishing jobs completed very rapidly and commercially formulated products assist with this efficiency. 
-Pure Chinese wood oil demands a more considered approach.

-For most tradespersons the notion of applying and wiping off a finish is counter-intuitive, they will tend to leave Chinese wood oil to pond which may be good practice for an oil with dryers but is not a suitable method for pure tung.
-Many trades persons have been using what they continue to be told is Chinese wood oil for many years and will resist the instruction above about application and rub back. They will tend to leave the coat wet which will cause grief.

-There is with Chinese wood oil no issue of the time window between coats such as applies to some poly-urethane finishes which can require that second and subsequent coats be applied after the solvents in the prior coat have sufficiently off-gassed but before all the chemical bonds have formed in the prior coat.
-Chinese wood oil is a component of many products marketed as Chinese wood oil but which are usually extended with other cheaper non-drying oils and consequently have to contain added toxic dryers and anti-fungals.

-Pure Chinese wood oil is not a high build "treacle" finish.
-Pure Chinese wood oil offers a low gloss 'woody' look.
-Pure Chinese wood oil is not a shiny membrane finish although can be buffed to a quite high lustre.
-Pure Chinese wood oil must be applied with thin "wiped off" coats. 

-Do not allow Chinese wood oil to pond or attempt to cure thick coats.
-Pure Chinese wood oil will cure to a very tough finish. 
After a few days the surface of the treated wood will be remarkably hard and suitable for buffing.
-Chinese wood oil has, even when used neat, a remarkable affinity for wood and penetrates better than any oil.
-Pure Chinese wood oil takes longer to cure (Chinese wood oil has no chemical dryers added).

-Chinese wood oil cures quicker, more completely and to a harder and far less oily finish than linseed oil.
-Chinese wood oil does not continue to darken over time as may linseed oil.
-Chinese wood oil is not as likely to support mould as linseed oil.
-Chinese wood oil has a natural resistance to UV.
-Pure Chinese wood oil can be touched up with maintenance coats or applied to restore areas of high wear with relative ease.

-Applications of pure Chinese wood oil do not demand as clean an environment in terms of airborne dust, insects etc as do membrane finishes.
-Chinese wood oil is very tenacious and the use of expensive application brushes is not recommended because they are impossible to fully clean.
-Chinese Wood Oil helps keep outdoor furniture nice by counteracting cracking, algae, fungus & mould. 
-Chinese Wood Oil also protects from water & moisture.

-Chinese wood oil will last far longer in storage than products with added chemical dryers.  
When storing keep sealed off from air, cool and dry, out of the sun and try to expel any air from the head of the container.  
Note that we supply 5, 10, 15 and 20 litre consignments in multiples of 5 litre plastic jerry cans filled past their official capacity.  
This means only the contents of one 5 litre jerry can need be exposed to air. 
Stored as suggested, and with minimal air in the head of the container, Pure Chinese wood oil can be stored for at least a couple of years.

-Use Chinese Wood Oil for all types of interior and exterior wood:

-Chinese Wood Oil finish for all types of wood:
China Wood Oil can be used for all types of wood, such as oak, walnut, pine, cedar, teak, plywood. 
Apply Chinese Wood Oil wood finish directly on untreated or porous wooden surfaces and oiled or waxed wooden surfaces with open pores. 
Is the wood sealed with varnish or lacquer or is there another reason why the wood pores are closed? 
Then you should first remove the old finishes by sanding the wood.

-Chinese Wood Oil colours the wood darker:
Chinese Wood Oil is a dark brown oil. 
After application, the wood is much darker in color. 
That is why it is especially used in the garden for wooden garden furniture, closures, etc.

Welcome to your enquiry!
-Chinese Wood Oil is used in quick-drying varnishes and paints, as a waterproofing agent, and in making linoleum, oilcloth, and insulating compounds. 

-Chinese Wood Oil was used as a preservative for wood ships. 
Chinese Wood Oil penetrates the wood, then hardens to form an impermeable hydrophobic layer (repels water) up to 5 mm into the wood. 
As a preservative Chinese Wood Oil is effective for exterior work above and below ground, but the thin layer makes it less useful in practice.
-The wood of the tree is lightweight and strong, and is sometimes used as a substitute for balsa or basswood. 
The some parts of the tree have been used for medicinal purposes in the past.

-Chinese Wood Oil gives a matte finish.
Maintenance of a surface finished with Chinese Wood Oil is very simple. 
By periodically applying a thin new layer of Chinese Wood Oil with the aid of a cloth, you can repair any damage and also increase the patina of older objects. 
A floor or other wooden object that is provided with a layer of Chinese Wood Oil therefore never needs to be sanded again, but only to be given a new layer each year.

-Due to the strong water-repellent character of Chinese Wood Oil, Chinese Wood Oil is an excellent finish for kitchen tables, cutting boards, shower paneling and the like. 
Because Chinese Wood Oil is also food safe, Chinese Wood Oil can also be used beautifully for finishing children's toys and furniture. 
-Chinese Wood Oil is also a great product in the workshop.

Chinese Wood Oil goes without saying that the wooden handles of your chisels in the workshop experience Chinese Wood Oil as a real indulgence.
-Chinese Wood Oil is an extraordinary hard wearing finish, suitable for all interior and exterior timbers, cork, steel and stone.

-The surface must be smooth and dust-free before the Chinese Wood Oil is applied. 
Any sanding sealers, stains and pore fillers must also already be used. 
The first layer of Chinese Wood Oil should be applied well and can be rubbed into the wood using an old rag. 
Allow the Chinese Wood Oil to settle for about 30 minutes and then remove the excess Chinese Wood Oil with clean, dry cloth. 
After half an hour, check whether there are still wet areas and remove the excess Chinese Wood Oil. 
Let the layers dry for 3 to 7 days before applying the next coat. 
How many layers of Chinese Wood Oil are required is determined by the workpiece. 
For most objects, usually 1 to 2 layers of Chinese Wood Oil are sufficient; on objects made from head wood sometimes 10 layers of Chinese Wood Oil can be applied.

-To thin this Chinese Wood Oil, turpentine oil is used (note: turpentine oil is slightly different than turpentine). 
You can mix the Chinese Wood Oil with, for example, 50% turpentine oil so that you not only increase the penetrating power (and therefore the protective value) but also shorten the drying time of the Chinese Wood Oil. 
If you want to shorten the drying time of Chinese Wood Oil even further, you can of course add a dash of Siccative to the turpentine oil (if necessary).

-Pure Chinese Wood Oil finish protects and seals the wood
-100% Pure Chinese Wood Oil finish seals the wood and leaves a hard wearing resistant barrier against water and stains. 
Chinese Wood Oil wood finish or Tung Oil is known to provide a long lasting coat and extend the lifetime of wood.
-Special oil for the maintenance of cutting boards or for the treatment of wooden protective covers and unprocessed handles.

-Wood Projects:
Chinese tung oil is one of the most commonly used oils to dry woods. 
Chinese Wood Oil is extracted from a tung tree seed. 
This tree is native to China. 
For many centuries, people have been using it to make a water-resistant finish. 
Chinese Wood Oil is applied to boats and other wooden objects. 
Chinese Wood Oil is a great alternative to drying oils, like linseed, soy, and walnut. 
Because of Chinese Wood Oil's versatile nature, people are using Chinese Wood Oil for their wood projects. 

-Using a lint free, cotton cloth, good quality brush or “00” or “000” steel wool, apply in the direction of the grain. 
Allow sufficient time for Chinese Wood Oil to penetrate into the grain becoming “tacky” and rub hard with a lint free, cotton cloth before oil dries. 
Leave for 6 – 24 hours or until dry and repeat application.
Apply as many coats as required to achieve desired finish.

-“00” and “000” steel wool or wet or dry paper may be used to cut back surface. 
May be used as filler when French Polishing.
-Ideal for interior or exterior timber, steel, stone and cork.
-Chinese Wood Oil impregnates, protects and preserves outdoor furniture from sun, rain and wear.
The handy spray bottle means that you avoid smudges and spills.

-Many craftsmen will use boiled or polymerized Chinese Wood Oil, and Chinese Wood Oil’s also common for manufacturers to mislabel products as Chinese Wood Oil when they’re not. 
-Pure Chinese Wood Oil is recommended for wood finishing of kitchen tables, chopping blocks, wood, and concrete countertops, wood floors, concrete floors, refinishing wood floors, outdoor decks, outdoor furniture, wood siding, log homes both interior and exterior and similar uses. 
Chinese Wood Oil's non-toxic nature makes Chinese Wood Oil particularly appropriate for children's toys and furniture. 

-Chinese Wood Oil gives good protection to wood paneling and molding.
-Chinese Wood Oil adheres very well to metal, and a light coat rubbed onto tool steel is an effective rust inhibitor. 
Wooden handles will also benefit from the occasional coat. 
The surface should be dusted to remove all loose particles.
Alternatively, you can lightly sand the first coat before applying a second. 

-Any filling, sealing or staining must be done before Chinese Wood Oil is applied. 
The first coat should be a liberal one, and you can rub it over the wood with your hand, a soft rag. 
Allow this application to sit for 20 minutes so Chinese Wood Oil can soak in, then remove any excess with clean soft rags. 
Check after about half an hour for any seeping, and rub this off as well. 
Let dry completely (24-48 hours) between coats. 
For woods with very open pores, allow an extra 24 hours drying time.

-Chinese Wood Oil can be applied pure or with Citrus Solvent added. 
Thinners such as Citrus Solvent can accelerate the drying process and greatly improve penetration.
-Chinese Wood Oil has been known about for hundreds of years in China, where it was used as a preservative for wood ships. 
Chinese Wood Oil penetrates the wood, then hardens to form an impermeable hydrophobic layer (repels water) up to 5 mm into the wood. 
As a preservative Chinese Wood Oil is effective for exterior work above and below ground, but the thin layer makes Chinese Wood Oil less useful in practice.

-Chinese Wood Oil seeps into the grain of the wood, giving Chinese Wood Oil a perpetual wet look that highly accentualizes the grain of the wood, commonly referred to as “making the grain pop”. 
Because of this, the color of the wood is slightly darkened, giving the wood a rich, warm color that is very pleasing.
-Chinese Wood Oil provides a relatively hard surface finish that, as long as the surface integrity is intact, provides a waterproof finish that is impervious to dust, alcohol, acetone (nail polish remover), and various acids such as fruit and vegetable acids (orange juice).

-As long as the surface bearing the tung oil has not been damaged, Chinese Wood Oil provides the following benefits:
*Waterproof (or at least highly water resistant on a well maintained surface)
*Resistant to alcohol
*Resistant to acetone (such as nail polish or remover)
*Resistant to fruit acids and vegetable acids (such as orange juice)
*Flexible. 

*Oil finishes continue to protect as the wood expands and contract.
*Accentuates the texture and grain of the wood
*Easy to apply (rub on, rub off)
*Very forgiving during application
*Easy to re-apply if the original finish becomes worn or damaged
*Non-toxic and food-safe (Pure form only! Be careful!)

-Chinese Wood Oil started out as a popular choice for boat decks and floors but because of Chinese Wood Oil's flexible, durable and food safe properties, is now more widely used on a whole host of projects. 
Because Chinese Wood Oil doesn’t darken and is resistant to mould, Chinese Wood Oil is widely used on interior and outdoor furniture, wooden toys, cabinets and musical instruments such as guitars and more.

-Chinese Wood Oil is a 100% pure oil meaning Chinese Wood Oil comes without any heavy metals, additives, or distillates. 
Most other oils can be anything from a thinned-down varnish to polymerized tung, and most have petroleum distillates added. 
Ours will not build a gloss finish or heavy finish but will penetrate deeply into the wood to enhance character and water resistance while creating a great wood finish. 
This makes our pure Chinese Wood Oil perfect for uses such as wood countertops, bowls, butcher blocks, cutting boards, chopping blocks, outdoor furniture, decks, wood siding, wood flooring, concrete, brick, and just about any porous surface that needs an environmentally friendly product.

-Keep in mind, that Chinese Wood Oil’s a natural “Honey” color. 
Cheaper grades are generally off-color or greenish. 
Other companies will not talk about the color because Chinese Wood Oil’s their quality does not uphold. 
But color is important, you are using Chinese Wood Oil to finish your wood so Chinese Wood Oil makes sense that the way Chinese Wood Oil looks plays a big part in the finish of your product.

FIVE REASONS CHINESE WOOD OIL IS THE BEST WOOD OIL:
Completely pure Chinese Wood Oil is one of the most natural wood oils you can find on the market today. 
Chinese Wood Oil is food safe and kid safe and also an eco-friendly and sustainable option that you can use on virtually any type of wood surface.

There is nothing quite like the peace of mind that comes with knowing you are using a safe product on your home’s wood items. 
However, there are even more benefits that come with pure oil.

Chinese Wood Oil Can Waterproof Wood- According to the original history of Chinese Wood Oil, Chinese Wood Oil was used to treat Chinese trade ships to keep these ancient boats sealed and waterproof. 
This natural Chinese Wood Oil hardens upon contact with the air and instantly creates a durable shield over the wood.

Chinese Wood Oil is Resistant to Harsh Chemicals- All-natural Chinese Wood Oil is resistant to alcohol and to acetone. 
This includes harsh elements like nail polish remover. 
This hard exterior shell has a hard, almost wet-like finish that still allows the natural grain of the wood shine through.

Chinese Wood Oil is 100% Food Safe:
If you are looking for an oil that is completely food safe, then Chinese Wood Oil is a great option. 
Chinese Wood Oil is not only FDA approved to be used near food and on food prep surfaces, Chinese Wood Oil is also resistant to fruit and vegetable acids.

You can Expect Flexibility:
Chinese Wood Oil is not only flexible in terms of the different ways you can utilize Chinese Wood Oil—but Chinese Wood Oil is physically flexible as well. 
This oil finish will continue to protect the wood as Chinese Wood Oil expands and extracts over time.

Chinese Wood Oil is Easy to Apply- Applying Chinese Wood Oil is simple, especially when compared to other wood oils. 
Simply rub it on and rub it off as needed for a virtually fool-proof finishing experience.

Chinese Wood Oil is important to remember that in order to take advantage of benefits like this, you must use 100% pure Chinese Wood Oil. 
There are other imitation products out there that use Chinese Wood Oil together with other chemicals. 
These finishing products will not give you the same natural benefits as pure, raw tung oil.

PROPERTIES & CHARACTERISTICS of CHINESE WOOD OIL:
-All-natural finish that is water and alkali resistant and offers a protective barrier.
-Will not darken with age as other finishes will.
-Chinese Wood Oil resists marring, penetrates well, is elastic, and is unlikely to check.
-Chinese Wood Oil builds quickly, consolidates the wood surface, and builds a transparent matte finish.

-Chinese Wood Oil will not mildew or bleed like linseed oil when dry which makes Chinese Wood Oil an excellent candidate for outdoor finishes.
-Chinese Wood Oil should be kept in an airtight container with minimum airspace.
-Chinese Wood Oil contains no thinners or driers and has a light nutty odor.
-Chinese Wood Oil can be mixed with any other of our Tung Oil Products (i.e. Dark Chinese Wood Oil, Dark Half, Half & Half, Outdoor Defense Oil)
-A Pure Chinese Wood Oil finish mixed with Citrus Solvent is an all-natural organic finish that is environmentally safe and food safe.

APPLICATION of PURE CHINESE WOOD OIL:
The surface should be smooth and dust free before the Chinese Wood Oil is applied. 
The first layer of Chinese Wood Oil needs to be applied well and can be rubbed into the wood using a dot cotton or an old rag. 
Let the Chinese Wood Oil retract for about 10 minutes and then remove the excess Chinese Wood Oil with clean, dry rags. 
After half an hour, check for wet places and remove the excess Chinese Wood Oil. 

Keep the layers dry for 2 to 3 days; Open Porige wood species prefer one more day longer, before applying a next layer. 
How many layers of Chinese Wood Oil are required is determined by the workpiece. 
For decorative objects, normally 2 to 4 layers of Chinese Wood Oil are more than sufficient; 
On objects that are used intensively or on the wood can sometimes be applied 10 layers of Chinese Wood Oil. 
To dilute this Chinese Wood Oil, turpentine oil is used (note: turpentine oil is slightly different from white). 

To do this, you can mix the Tung with, for example, 50% turpentine oil, which increases not only the penetrating power (and therefore the protective value), but also shortens the drying time of the Tung. 
If you want to shorten the drying time of Chinese Wood Oil even further, you can add a splash of Siccatief (possibly additional) to the turpentine oil. 
Because of the strong water-repellent nature of Chinese Wood Oil.

Chinese Wood Oil is an excellent finish for kitchen tables, cutting boards, shower fittings and the like. 
Because Tung food is safe.
Chinese Wood Oil can also be used beautifully for the processing of children's toys and furniture. 

Chinese Wood Oil is also a wonderful product in the workshop. 
Chinese Wood Oil gives a fine water repellent protection on all metal machine parts such as the tables and conductors of sawing, drilling and milling machines. 
Chinese Wood Oil goes without saying that the wooden handles of your chisels in the workshop Chinese Wood Oil are experienced as a real indulgence. 

Chinese Wood Oil gives as said a matte finish. For a silk sheen or a glossy surface use the ' improved wood oil ' or ' improved Danish oil ' respectively. 
These layers can be placed over the layers of raw tung. 
Maintenance of a Tung finished surface is very simple. 
By occasionally applying a thin new layer of tung with a swab you can repair any damage and also increase the patina of older objects. 
A floor or other wooden object fitted with a layer of Tung no longer has to be made bare but only to be fitted with a new layer to make the surface more beautiful. 

Raw Tung has a drying time of several days to a week. 
The advantage of this is that the oil continues to penetrate long; 
The disadvantage is that dust can also stick in the surface at that time. 
If you want to tung but a much shorter drying time, choose improved wood oil.

The number of coats of oil to be applied will be determined by the intended use of the piece. 
Two to four coats are enough for decorative work, paneling and molding. 
Surfaces that receive moderate to heavy use or handling could need up to six coats for maximum protection, plus a light renewal coat a couple of times a year. 
Apply until the surface reaches the saturation point. 

This will be evident as the surface will not absorb more oil. 
Renewal and building coats are quickly applied with cheesecloth, a lint-free cloth or old nylon stockings. 
This process will give you a surface that will stand up to vigorous use and spills: water will bead on the surface.

DIRECTION FOR USE of CHINESE WOOD OIL:
PREPARATION:
The surface should be dusted to remove all loose particles.
For better penetration the oil should be thinned one to one with Citrus Solvent.
Any filling or staining (water or alcohol stains work best) must be done before the oil is applied.
Using the Pure Chinese Wood Oil straight from the bottle would only be for the most thirsty surfaces like old weathered wood, hundred year old wood floors that were never finished or concrete.
The majority of all projects, you will thin 50% with thinners for the entire finishing process.

APPLICATION:
The first coat of thinned material should be a liberal one.
Apply with a natural bristle brush or sponge brush.
Allow this application to sit for a minimum of 40 minutes so Chinese Wood Oil can soak in. 
When Chinese Wood Oil soaks into the wood, apply another coat immediately. 

Continue to apply coats until wood is saturated and stays glossy for a minimum of 40 minutes but can be 1 ½ hours. 
If eighty percent of area stays glossy the wood cells are saturated.
Then wipe down the surface with clean rag material. 
Continue to check for any seeping in the next few hours, and rub this off as well. 
Let soak in completely over night between applications. 

Do not allow standing oil on the surface over night. 
Any standing or puddles oil should be wiped away with clean rags.
For woods with very dense pores like teak wood thin with two parts Citrus Solvent to one part oil will help Chinese Wood Oil absorb better for every coat.
Hang oil soaked rags up separately to dry.
Pure Chinese Wood Oil will take 7 to 10 days for a minimum cure and 15 to 30 days for a full cure.

Chinese Wood Oil can be applied pure or with Citrus Solvent added if a non-toxic finish is required.
Thinners can accelerate the drying process and greatly improve the penetration by cutting the first coat of oil with Citrus Solvent, mineral spirits or turpentine by 50%.
Do not use the “Green” thinners now being sold.  
They contain water and will not mix with Chinese Wood Oil.

The number of coats of oil to be applied will be determined by the intended use of the piece. 
Two to four coats are enough for decorative work, paneling and molding. 
Surfaces that receive moderate to heavy use or handling could need up to six coats for maximum protection, plus a light renewal coats a couple of times a year.
Apply until the surface reaches the saturation point. 
This will be evident as the surface will not absorb more oil.

Renewal and building coats are quickly applied with cheese cloth, a lint free cloth or old nylon stockings. 
This process will give you a surface that will stand up to vigorous use and spills; water will bead on the surface.
Do not get hung up on the number of coats, let the wood tell you when Chinese Wood Oil has reached Chinese Wood Oil's maximum saturation.
Pure Chinese Wood Oil’s matte finish will do nicely on certain pieces of furniture, but if a glossy finish is preferred you will need to buff and wax the finish, or use polymerized Chinese Wood Oil or a formulated Chinese Wood Oil based product.

INGREDIENTS/COMPOSITION of CHINESE WOOD OIL:
A Pure Chinese Wood Oil all-natural finish is water and alkali resistant offering a protective barrier. 
A Pure Tung Oil finish will not darken with age as other finishes will. 
Chinese Wood Oil resists marring, penetrates well, remains elastic and unlikely to check. 
Chinese Wood Oil builds quickly, consolidates the wood surface and builds a transparent matte finish. 

Pure Chinese Wood Oil finish will not mildew or bleed like linseed oil when dry which makes Chinese Wood Oil an excellent candidate for outdoor finishes. 
Chinese Wood Oil should be kept in an airtight container with minimum air space. 
Pure Chinese Wood Oil contains no thinners or driers and has a light nutty odor. 
A Pure Chinese Wood Oil finish mixed with Citrus Solvent is an all-natural organic finish that is environmentally safe and food safe.

HOW MANY COATS of CHINESE WOOD OIL SHOULD BE USED?
While there are many advantages to using Chinese Wood Oil, pure tung oil takes two to three days to harden, and needs at least five coats. 
Oil/varnish blends and wiping varnishes are faster-drying, more practical options, but such terms rarely appear on labels. 

CHOOSING THE RIGHT TYPE of CHINESE WOOD OIL FINISH
Penetrating Chinese Wood Oil finishes come in three varieties: pure Chinese Wood Oil, oil/varnish blends, and wiping varnish. 
They all share the benefits that Chinese Wood Oil imparts to a finish—durability, water resistance, resilient hardness, and color stability—depending on how much of Chinese Wood Oil they actually contain and what form Chinese Wood Oil takes.

WHY CONSIDER CHINESE WOOD OIL?
There are various reasons people opt for Chinese Wood Oil in their projects. 
As stated earlier, Chinese Wood Oil is versatile. 
Chinese Wood Oil is also durable and flexible, as well as food safe. 
You can use Chinese Wood Oil as a protective waterproof finish that will not darken or go rancid. 
Furthermore, Chinese Wood Oil dries faster than other drying oils. 

In that case, Chinese Wood Oil is easier to apply. 
Chinese Wood Oil is also less time-consuming as you do not have to wait for a lot longer to apply and re-apply the product.
Plus, Chinese Wood Oil offers a beautiful matte finish, unlike other oils. 
Chinese Wood Oil also adds depth to the woodgrain. 
As a result, you can see a styled finish that looks antique. 

PURE CHINESE WOOD OIL vs LINSEED OIL
Among natural finishes, Chinese Wood Oil surpasses shellac and linseed oil in hardness, durability, and water resistance. 
Chinese Wood Oil’s also food-safe, once cured.

CHINESE WOOD OIL FINISH (or MODIFIED CHINESE WOOD OIL)
In an effort to give the consumer a product that produces a look of Chinese Wood Oil yet gives a harder and faster drying finish, many vendors are offering products with names such as “Tung Oil Finish”. 
These products usually include metallic drying agents, thinners, or less expensive oil additives. 
These additives improve the penetration, hasten the drying time, and keeps the product cost reasonably low.

SHOULD YOU USE PURE or DARK CHINESE WOOD OIL:
Pure Chinese Wood Oil does not contain any additives. 
Chinese Wood Oil also does not create a heavy finish while giving the wooden object a glossy appearance. 
Chinese Wood Oil dries to any honey color object. 

If you opt for dark Chinese Wood Oil, you are still using pure Chinese Wood Oil but with non-carcinogenic resinous hydrocarbon. 
The added ingredient gives Chinese Wood Oil a darker appearance. 
In other words, if you wish to achieve a darker result, you may opt for dark Chinese Wood Oil. 
However, if you want a natural wood result, then just opt for pure Chinese Wood Oil. 

Many carpenters and hobbyists are adding Chinese Wood Oil to their finish. 
They use Chinese Wood Oil as a protective finish in various wood projects.
Chinese Wood Oil is applied to bamboo, brick, concrete and even metal surfaces. 
Chinese Wood Oil is also a favorite drying agent to finish wood floors, furniture, guitars, decks and more. 

The amount of Chinese Wood Oil you need will depend on your project. 
One gallon of Chinese Wood Oil is enough to cover 400 square feet surface. 
You may need up to five coats. 
However, Chinese Wood Oil hinges on how porous the wood is. 

When you apply tChinese Wood Oil to the wood surface, make sure that Chinese Wood Oil is clean. 
Eliminate grease, dirt, and dust on the surface as Chinese Wood Oil affects the result. 
You may choose to sand the surface to eliminate any finish that is present. 
You can apply Chinese Wood Oil to bare surfaces or you may choose to apply Chinese Wood Oil over another coat. 

To properly remove dust, make sure to use sandpaper and vacuum Chinese Wood Oil well. 
Make sure to use thinner Chinese Wood Oil to make the application faster. 
Chinese Wood Oil also dries the wood faster. 
You must not thin Chinese Wood Oil when you use Chinese Wood Oil on unfashioned wood floors or concrete floors. 
The first layer must have a generous amount. 

APPLYING CHINESE WOOD OIL:
Applying Chinese Wood Oil is an easy job. 
Make sure that your wooden surface is clean and dry. 
You can thin the Chinese Wood Oil with Pure Solvent or another (natural) solvent (1:1). 

This will make Chinese Wood Oil easier to apply and penetrate into the wood. 
If you’re treating weathered wood, old unfinished floors or highly absorbent surfaces, you should not thin Chinese Wood Oil. 
Soak up some oil with a lint-free cloth, brush or paint roller. 
Rub Chinese Wood Oil with a cloth in the direction of the wood grain. 

Wait at least 30 minutes for Chinese Wood Oil can penetrate the wood. 
Remove excess Chinese Wood Oil with a cloth and allow to dry for a few hours up to one day between coats depending on the wood. 
If the wood is very absorbent or porous, you may need to apply 4 coats or more of 100% Pure Chinese Wood Oil. 
Dry used rags or cloths flat to prevent the small possibility of spontaneous combustion.

Maintain and repair damaged or scratched areas locally.
Re-apply one or two coats of Pure Chinese Wood Oil once a year and the wood will keep Chinese Wood Oil's natural look. 
You can repair damaged or scratched areas locally.

COMPOSITION of CHINESE WOOD OIL:
The fatty acids in Chinese wood oil and their concentration are listed.
Fatty acid composition of Chinese wood oil:
Alpha-eleostearic acid    82.0%
Linoleic acid    8.5%
Palmitic acid    5.5%
Oleic acid    4.0%

The primary constituent is a fatty acid with a chain of 18 linked carbon atoms or methylene units containing three conjugated double bonds. 
They are especially sensitive to autoxidation, which encourages cross linking of neighbouring chains, hence hardening of the base resin.

HISTORY of CHINESE WOOD OIL:
The Chinese wood oil tree originates in southern China and was cultivated there for tung oil, but the date of cultivation remains unknown. 
During the Song Dynasty, Chinese wood oil was used for waterproofing on ships. 
The word "Tung" is etymologically derived from the Chinese 桐 tóng. 
The earliest references for Chinese use of Chinese wood oil is in the writings of Confucius around 500 to 400 BC.

Referred to by Confucius as early as 400 BC and also known as China Wood Oil, Tung Oil is believed by many to be the finest natural wood finish in the world. 
Chinese wood oil is extracted from the nuts of the Tung Tree - Aleurites fordii - native to east Asia. 
Legend has it that the Great Wall Of China was sealed with Chinese Wood Oil. 

Chinese wood oil comes from the seeds of several species of Aleurites, primarily Aleurites fordii, a deciduous shade tree native to China. 
Chinese wood oil belongs to the Euphorbia Family (Euphorbiaceae) along with the candlenut tree (A. molucanna), another species with seeds rich in unsaturated oils. 
For centuries Chinese wood oil has been used for paints and waterproof coatings, and as a component of caulk and mortar. 
Chinese wood oil is an ingredient in "India ink" and is commonly used for a lustrous finish on wood. 
Some woodworkers consider Chinese wood oil to be one of the best natural finishes for wood.

Other unsaturated plant oils, such as castor oil and linseed oil, take longer to dry and leave an oily residue until they soak into the wood surface. 
Chinese wood oil's ability to dry quickly and polymerize into a tough, glossy, waterproof coating has made Chinese wood oil especially valuable in paints, varnishes, linoleum, oilcloth and printing inks. 
The oil-rich seeds are produced inside a thick, woody endocarp layer and are the source of Chinese Wood Oil used on fine furniture.

The word Tung is an ancient Chinese term for heart. 
Today, the term also refers to the large, dark green, heart shaped leaves of the Tung tree. 
This is a fast growing, deciduous tree that reaches a height of about forty feet when mature. 
The life span of a Tung tree is about thirty years. 
Fruit bearing begins in the third year of tree growth. 

The Tung fruit occurs in clusters, each of which bear four or five nuts. 
When the nuts are dried and pressed they yield about twenty percent oil. 
Under favorable conditions an acre of Tung trees will produce about two tons of nuts and eight hundred pounds (one hundred gallons) of raw Tung Oil annually. 
Successful cultivation of Tung trees requires exact climatic conditions, including the proper ratio of warm and cool days. 
The major growing areas include China, Argentina, Paraguay, and parts of Africa.

The first record of Chinese wood oil appears in the writings of Confucius dated about 400 B.C..
Even then, the Chinese recognized the amazing qualities of Chinese wood oil. 
Throughout their history, the Chinese have used Chinese wood oil to waterproof the masts and sails of junks (boats), to finish furniture of royal families and according to legend, to seal the Great Wall! 
When Marco Polo returned from China, he brought tales of the wonderful "China Wood Oil". 
But Chinese wood oil was unable to capture the attention of the West until this century.

Pure Chinese Wood Oil (China wood oil) is an all-natural finishing product that provides a tough, flexible and highly water-resistant coating. 
Chinese Wood Oil is classed as a drying oil along with linseed, poppy seed, safflower seed, walnut, soybean, oiticica, and a few other oils. 
Although it is relatively new to the Western world, Chinese Wood Oil also known as tung oil has been known for centuries to the Chinese, and until this century, China was the main source for Chinese Wood Oil. 
Chinese Wood Oil comes from the seed of the tung trees, Aleurites fordii and Aleurites Montana, deciduous trees that are very susceptible to frost damage. 

This vulnerability has restricted the cultivation of the tung trees to China and South America. 
Chinese Wood Oil (China wood oil ) received a wide application in China: in the building trades as a treatment for both stone and wooden structures; in marine trades as a preservative and water repellant on wooden boats. 
It is said to have been introduced to the West by Marco Polo. 
From the 13th to the 19th century, tung oil had only limited use in the West. 

More recently, Chinese Wood Oil has gained favor over linseed oil for wood finishing because Chinese Wood Oil is faster drying and does not darken as much with age.
Pure Chinese Wood Oil comes from cold pressing of the seed or nuts of the tung tree, which mainly grow in the mountainous regions of China away from industrialization and pollution.  
Climate, soil and air quality are essential for high quality oil.  

Some low priced marketers will package South American Tung Oil (dark, greenish in color) and sell it as the higher quality Chinese.  
The high quality oil offers superior color, fast drying and long elastic finish.  
Elasticity is an important factor as the oil must continue to flex with the expansion and contraction of the substrate on which it is applied.

Chinese Wood Oil’s one of the first and remains to be one of the only truly “Green” or environmentally friendly finishes. 
Chinese Wood Oil is all natural and contains zero VOC’s.  
Chinese Wood Oil’s an all – natural finishing product that provides a tough, flexible and highly water-resistant coating or wood finish. 

Chinese Wood Oil is classed as a drying oil along with linseed, poppy seed, safflower seed, walnut, soybean, oiticica and a few other oils. 
Although Chinese Wood Oil is relatively new to the Western world, Chinese Wood Oil has been known for centuries to the Chinese, and until this century, China was the main source for the oil. 
Chinese Wood Oil comes from the seed of the tung trees, Aleurites fordii and Aleurites montana, deciduous trees that are very susceptible to frost damage. 
This vulnerability has restricted the cultivation of the tung trees to China and South America. 

Chinese Wood Oil’s in the building trades as a treatment for both stone and wooden structures; in marine trades as a preservative and water repellant on wooden boats for centuries. 
Chinese Wood Oil is said to have been introduced to the West by Marco Polo.  
From the 13th to the 19th century, Chinese Wood Oil had only limited use in the West. 
More recently, Chinese Wood Oil has gained favor over linseed oil for wood finishing because Chinese Wood Oil is faster drying and does not darken as much with age.

TESTING of CHINESE WOOD OIL:
Chinese wood oil is strongly recommended that Pure Tung is tested on an off-cut or equivalent piece of the wood that the finish is intended for. 
This proving process will determine thinning ratios and your technique and will help to ensure that your expectations are in line with what can be achieved. 
This advice is especially relevant to oiled finishes which, by their nature, can absorb oil deep into the wood and which are therefore unlike skin finishes which can often be more easily removed with strippers or sanding if you change your mind or are unhappy with the outcome.

TUNG OIL VERSUS OTHER FINISHES
In recent years, those who appreciate the warm richness of beautiful wood have begun to realize what the ancient Chinese knew; when turned into a finishing product, Chinese wood oil is the finest natural wood finish in existence and has yet to be duplicated synthetically!

Man's ingenuity has created many synthetic finishes, including lacquer, shellac, and varnish all of which protect wood with a hard impervious layer. 
But these surface finishes prevent the development of patina, the lovely depth and tone that only natural aging can produce. 
Eventually synthetic finishes will break down and discolor, when that happens the entire surface must be removed by labor intensive stripping and sanding before another coat is applied.

Penetrating finishes formulated with linseed, soy or paraffin oils actually go into the wood and enhance its natural beauty, but these oils often dry incompletely and fail to form a hard and durable surface. 
Furthermore, they develop a gummy build-up when additional coats are applied. 
Linseed oil, the most commonly used penetrating finish, darkens and changes color with time and finally disintegrates.

A Chinese wood oil finish is hard yet flexible, waterproof and impervious to alcohol and many food acids. 
Chinese wood oil as a penetrating oil allows wood to continue Chinese wood oil's aging process and to develop Chinese wood oil's patina. 
The wood's rich color and grain are enhanced by the natural ambering (coloring) of Chinese wood oil over time. 
Any sign of wear disappears when a thin "maintenance" coat of oil is rubbed in. 

The maintenance coats, rather than cause a build-up, actually improve the patina as they protect and preserve the wood. 
A floor, a piece of furniture, or any other wood object finished and maintained with Chinese wood oil will never have to be stripped again. 
The finish will become more beautiful with time.

POLYMERIZED CHINESE WOOD OIL:
One of the main complaints of Chinese Wood Oil is the time Chinese Wood Oil requires to properly cure once applied. 
Vendors have therefore produced a product called polymerized Chinese Wood Oil that has been through a cooking process to partially complete the molecular process that drying oils go through.

PREPARATION of CHINESE WOOD OIL:
Since Chinese Wood Oil will highlight the grain and surface of the wood, Chinese Wood Oil will also highlight any surface blemishes and scratches that are left behind. Therefore, take your time to prepare the wood surface before you start to apply the product.

Sanding sealers are usually used to fix problems with uneaven absorption of stains, however it is not required under penetrating oil finishes such as tung oil. 
If you do choose to use sanding sealers, it is recommended that you are sanding to 180/220 grit, and only move on to finer sanding once the sealer is applied.

Sand the surface using progressively finer sandpaper until you reach 220 grit (or optionally 320-dry grit) sandpaper. 
This will leave the surface smooth and there should be no visible scratch marks that remain.

APPLICATION of CHINESE WOOD OIL:
Use any clean, lint-free rag to apply Chinese Wood Oil. 
If you use a rag that has rough-cut edges, be sure to fold the rag so the rough edges are held in your hand and are not on the wood surface, since any loose wood fibres may catch the edge of your cloth and leave troublesome lint behind.

Apply a small amount of Chinese Wood Oil to your cloth (not the wood surface) and proceed to apply Chinese Wood Oil to the work surface. 
Work from the least accessible areas (interior or underside) first and work towards the easiest sides. 
This will keep you from putting your elbow or forehead against a freshly oiled surface.

Apply by rubbing along the grain. 
Do not starve the wood, meaning you should not have to rub hard or often to get the surface wet, and if you are then re-oil your rag more often. 
Do not over-saturate the surface either, meaning the surface should be wet but the surface should not have any standing puddles. 
If there are any puddles, remove them before continuing on to the next section of your project.

Approximately 1/2 hour after applying Chinese Wood Oil, rub the project with a clean rag to remove any excess surface oil. 
Some people feel that a more vigorous buffing heats Chinese Wood Oil and increases its penetration into the wood surface, however, this is an optional effort that may produce minimal returns at the expense of your elbow grease.

Let Chinese Wood Oil stand for at least 24 hours, or until dry. 
It may take weeks for a full curing/drying, but I am referring to the absorption of the oil by the wood surface. 
To obtain a super-smooth finished surface, rub the project surface with 0000 steel wool (or equivalent). 
The dust produced from this sanding should be a white powder, and if you get a gummy resin instead, wait another day before proceeding. 
Repeat the application of the oil, 1/2 rest period, and removal of the excess.

To get maximum protection, you should apply 3 coats of full-strength Chinese Wood Oil. 
You should also have sanded with 0000 steel wool the day after applying each coat.

As an optional step, you can use thin the first coat of tung oil by 50% or more using turpentine or naphtha. 
This will greatly increase its penetration into the wood surface, but you should still apply three coats of full-strength Chinese Wood Oil on top. 
Please note that if you thin the first coat, the project will no longer be food-safe!

How do you know the surface is fully cured and has achieved its full hardness? 
If you push your fingers across the grain at various locations on your project, your fingers should slide smoothly and easily across the surface without any drag or grab. 
If there is any resistance, then the surface is not fully cured, and you should give it additional time before applying a different finish (such as shellac or paints).
