Rosin, also called colophony or Greek pitch (Latin: pix græca), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components.
Rosin is semi-transparent and varies in color from yellow to black.
At room temperature rosin is brittle, but it melts at stove-top temperature.
Rosin chiefly consists of various resin acids, especially abietic acid.
The term "colophony" comes from colophonia resina, Latin for "resin from Colophon," an ancient Ionic city.

Gum rosin becomes sticky when warm and has a faint pinelike odour.
Gum rosin consists of the residue obtained upon distillation of the oleoresin (a natural fluid) from pine trees (the volatile component is spirit of turpentine); wood rosin, obtained by solvent extraction of the stumps, is usually of a darker colour.

Gum rosin is an exudate gum, which is extracted from pine trees.
Gum rosin consists of abiatic acid, palaustric acid and neoabetic acid.

Rosin is brittle and friable, with a faint piny odor.
Gum rosin is typically a glassy solid, though some rosins will form crystals, especially when brought into solution.
The practical melting point varies with different specimens, some being semi-fluid at the temperature of boiling water, others melting at 100 °C to 120 °C.
Gum rosin is very flammable, burning with a smoky flame, so care should be taken when melting it.
Gum rosin is soluble in alcohol, ether, benzene and chloroform.

Rosin consists mainly of abietic acid, and combines with caustic alkalis to form salts (rosinates or pinates) that are known as rosin soaps.
In addition to its extensive use in soap making, rosin is largely employed in making varnishes (including fine violin varnishes), sealing wax and various adhesives.
Rosin is also used for preparing shoemakers' wax, for pitching lager beer casks, and numerous other purposes such as providing backing surfaces to tin ware, copper ware, or even silver and gold vessels when embossing or engraving them.
Its relatively low melting point, and firm solid form allows liquid rosin to be poured into the vessel, and when cooled allows embossing or engraving of the vessel without deforming the vessel - even if it has a skin which is quite thin.
Afterwards, the object can be reheated in an oven, and the rosin poured out for reuse.
Any remaining rosin film can easily be rinsed away with alcohol or other solvents.

Rosin is also sometimes used as internal reinforcement for very thin skinned metal objects - things like silver, copper or tin plate candlesticks, or sculptures, where it is simply melted, poured into a hollow thin-skinned object, and left to harden.

The type of rosin used with bowed string instruments is determined by the diameter of the strings.
Generally this means that the larger the instrument is, the softer the rosin should be.
For instance, double bass rosin is generally soft enough to be pliable with slow movements.
A cake of bass rosin left in a single position for several months will show evidence of flow, especially in warmer weather.

Gum Rosin is a natural solid form of pine oleoresin from pine trees, according to the specification, the range of colors from yellow to black, so it was also called colophony.
Gum Rosin is a crude raw material used on industrial, on the ordinary application, such as paper making, soap, lubrication oil for stringed instruments.
But we can see the demonstrable weakness, such as the dark color, high acid value, or chemical structural instability.

For the refined preparation process of coatings, inks, adhesive and agriculture.
Modification of gum rosin is the research trend on market.

Abietic acid is the main ingredient of rosin, it can be synthesized with others matter to produce series optics reactive materials and biotic reactive materials; these materials have the special function for human and others organism.

Rosin firstly converted into hydrogenated rosin and then used to produce chewing gum.

Rosin mainly is used as solding aid and metal polishing agent. Rosin is a kind of weak acidity matter, it can remove oxidation film from the metal surface and slightly erode the surface of the metal, and therefore, lots of solding aid agents contain rosin.

Rosin is a basic material for paint industry because rosin is easy to dissolve in alcohol, gasoline, turpentine, and others organic solvent. Rosin always is converted to resonate, and then refine with drying oil such as tung oil and mix with volatility solvent to produce various lacquers.
Rosin also take an important role in producing road coating, rosin firstly converted to rosin malefic ester or polymerized rosin or disproportionated rosin Polyols ester, and then used to make the thermoplastic coating for road sign injunction.

Most rosins were applied to papermaking industry as the sizing agent.
Rosin paper sizing agent can prevent printing oil soaking and be dispersing from paper, improves the strength and smoothness of paper; enhances the anti-abrasion of paper.
But crystal rosin is unfit for making paper sizing agent due to the difficulty of saponification, subsequently makes the spot on the paper; sometimes even makes the pipe jam in paper sizing agent producing.

Rosin is the ingredient of depilatory wax.
Rosin’s the traditional formula that effectively removes unwanted hair, and formulated for each skin and hair type.

Rosin always replaces a part of grease to produce soap because rosin has a similar character with fatty acid and cheaper than the fatty acid, but the consumption decline gradually in recent years.

Rosin is used as the softener in synthetic rubber industry; it enhances the plasticity, tears strength, heat resistance, flexibility and anti-abrasion of synthetic rubber; also rosin can be used as dispersant and emulsification in the synthetic rubber industry.
After the seventies of twenty century, about 20% of the total annual output of rosin was used in synthetic rubber industry.

Gum rosin is a pale yellow, transparent solid.
Gum rosin is a natural organic compound that is mainly composed of resins.
Uses: Paint, manufacture of paper, soap, and printing ink.

A translucent yellowish to dark brown resin derived from the stumps or sap of various pine trees, composed chiefly of abietic acid and related compounds, and used to increase sliding friction, as on the bows of certain stringed instruments, and to manufacture a wide variety of products including varnishes, inks, linoleum, adhesives, and soldering compounds.
Also called colophony.

Gum rosin is produced by the removal of volatiles from the resin of various pine species; the distillate is turpentine and the residue gum rosin.

Gum rosin is a natural material produced using a range of distillation parameters.
This means that although all gum rosins should have broadly similar properties and behaviours, different batches of gum rosin will differ in the specifics of their physical, and potentially chemical, properties.
At room temperature gum rosin appears a glassy, brittle, transparent solid with colours ranging through yellows, browns and possibly orange.
At elevated temperature gum rosin becomes a liquid at 'human' timescales (seconds to minutes).
Gum rosin may be considered similar to aluminosilicate glasses in that it is a visco-elastic material.
Even at 20°C gum rosin can deform viscously given sufficient time.
At ~ 40°C gum rosin will respond more like a brittle (frozen) solid to strain rates > 1 s-1, and more like a viscous (melted) liquid when strain rates are < 1 s-1.
There is not a sudden change in properties at a strain rate of 1 s-1, but a more gradual change over 2 - 3 orders of magnitude of strain rate.
Gum rosin was also inferred to have a yield strength.

This complex rheological behaviour, dependent on temperature and timescale of deformation, has similarities to the behaviour of silicate melts and glasses that comprise the volcanic system. This makes gum rosin a potential analogue material to study the behaviour of hot rocks under a range of deformation conditions.
In the laboratory, experimental temperatures will be < 100°C, considerably easier, cheaper and safer to work with than an alumino-silicate at several-100°C, especially with significant volumes of material.

Gum rosin is one of the main raw materials of ink, adhesive, pharmaceutical, and varnish and gum industries.

Gum rosin is positively differentiated from other renewable chemicals because of its chemical structure.
When used in combination with other polymeric structures, hydrocarbon-rich biomass of the gumrosin gives a hydrophobic effect, while the hydrophanthrene structure increases its thermal properties.

The gumrosin resin usually consists of 90% acidic resin and 10% neutral substance.
The resin acid is isomer with abietic acid. The rest is dehydroabietic acid and dehydroabietic acid.
The glycerin ester resin is obtained from the gum rosin resin by esterification with glycerin.

In the literature, the gum rosin resin acids were reacted with different monomeric structures to give functional properties and many biodegradable and biocompatible polymeric structures were obtained.

Gum Rosin Uses:

Most rosin is used in a chemically modified form rather than in the raw state in which it is obtained.
rosin consists primarily of a mixture of abietic-type and pimaric-type acids with smaller amounts of neutral compounds.
This intrinsic acidity, coupled with other chemical properties, enables it to be converted to a Large number of downstream derivatives which are used in a wide range of applications.
The derivatives include salts, esters and maleic anhydride adducts, and hydrogenated, disproportionated and polymerized rosins.
Rosins most important uses are in the manufacture of adhesives, paper sizing agents, printing inks, solders and fluxes, various surface coatings, insulating materials for the electronics industry, synthetic rubber, chewing gums and soaps and detergents.

Rosin is extensively used for its friction-increasing capacity in several fields:

Players of bowed string instruments rub cakes or blocks of rosin on their bow hair so it can grip the strings and make them "speak", or vibrate clearly.
Extra substances such as beeswax, gold, silver, tin, or meteoric iron are sometimes added to the rosin to modify its stiction/friction properties and the tone it produces.
Powdered rosin can be applied to new hair, for example with a felt pad or cloth, to reduce the time taken in getting sufficient rosin onto the hair.
Rosin is often reapplied immediately before playing the instrument.
Lighter rosin is generally preferred for violins and violas, and in high-humidity climates, while darker rosins are preferred for cellos, and for players in cool, dry areas.
There are also specific, distinguishing types for basses—for more see Bow (music).

Gum rosin potentially forms a useful analogue for lava flows, with hot (80°C +) gum rosin as the analogue magma source.
As the gum rosin cools it will increase in viscosity and solidify (strain rate dependent) in similar fashion to liquid rock.

Gum rosin has been used in the analogue study of magma flow and degassing in volcanic conduits.
For these studies gum rosin is mixed with a volatile organic solvent; gum rosin is the analogue liquid rock and the organic solvent the analogue volatile (H2O, CO2).

Gum rosin organic solvent solutions used experimentally are liquid at room temperature, compared to 'pure' gum rosin being a solid.
When the ambient pressure is reduced below that of the saturated vapour pressure of the volatile organic solvent above the solution, saturation has been exceeded and active degassing occurs.
Therefore, gum rosin organic solvent solutions at room temperature (20°C) and low pressure become analogous to a volatile saturated magma at much higher temperature (i.e., 800 - 1300°C) and pressure.

Comparing hydrated magma with gum rosin organic solvent on the basis of weight percent of the volatile in the melt does not attempt to scale appropriately for the physics of exsolution. When dissolved, the volatile can be considered to have a partial density similar to that of the pure liquid 'volatile', i.e., in the region of a few 100 to 1000 kg/m3.
On exsolution into the gas phase density decreases by a factor of 100 to 1000, driving the expansion of the exsolving system.
Scaling of this phase transition in terms of the driving force is better achieved by expressing the dissolved volatile concentration in terms of moles per unit volume of liquid, with each mole of volatile exsolved expanding to a similar volume.
