In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on naturally occurring resins.
Rosin, also called colophony or Greek pitch, 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. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperature. It 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.

Tall oil, also called liquid rosin or tallol, is a viscous yellow-black odorous liquid obtained as a by-product of the kraft process of wood pulp manufacture when pulping mainly coniferous trees. The name originated as an anglicization of the Swedish tallolja. Tall oil is the third largest chemical by-product in a kraft mill after lignin and hemicellulose; the yield of crude tall oil from the process is in the range of 30–50 kg / ton pulp. It may contribute to 1.0–1.5% of the mill's revenue if not used internally.
Making an instrument of the violin family, also called lutherie, may be done in different ways, many of which have changed very little in nearly 500 years since the first violins were made. Some violins, called "bench-made" instruments, are made by a single individual, either a master maker, or an advanced amateur working alone. Several people may participate in the making of a "shop-made" instrument, working under the supervision of a master. This was the preferred method of old violin makers who always put their names on violins crafted by their apprentices. Various levels of "trade violin" exist, often mass-produced by workers who each focus on a small part of the overall job, with or without the aid of machinery.
The Auschwitz Protocols, also known as the Auschwitz Reports, and originally published as The Extermination Camps of Auschwitz and Birkenau, is a collection of three eyewitness accounts from 1943–1944 about the mass murder that was taking place inside the Auschwitz concentration camp in German-occupied Poland during the Second World War. The eyewitness accounts are individually known as the Vrba–Wetzler report, Polish Major's report, and Rosin-Mordowicz report.

Glycerol ester of wood rosin, also known as glyceryl abietate or ester gum, is an oil-soluble food additive. The food-grade material is used in foods, beverages, and cosmetics to keep oils in suspension in water, and its name may be shortened in the ingredient list as glycerol ester of rosin. It is also used as an ingredient in the production of chewing-gum and ice cream. Similar, less pure materials are used as a component of certain low-cost adhesives.

Hash oil, also known as honey oil or cannabis oil, is an oleoresin obtained by the extraction of cannabis or hashish. It is a cannabis concentrate containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. There are various extraction methods, most involving a solvent, such as butane or ethanol. Hash oil is usually consumed by smoking, vaporizing or eating. Hash oil may be sold in cartridges used with pen vaporizers. Preparations of hash oil may be solid or colloidal depending on both production method and temperature and are usually identified by their appearance or characteristics. Color most commonly ranges from transparent golden or light brown, to tan or black. Cannabis retailers in California have reported about 40% of their sales are from cannabis oils. Hash oil is an extracted cannabis product that may use any part of the plant, with minimal or no residual solvent. It is generally thought to be indistinct from traditional hashish, according to the 1961 UN Single Convention on Narcotic Drugs, as it is "the separated resin, whether crude or purified, obtained from the cannabis plant".
