Colophony is also referred to as rosin, or Greek pitch (Latin: pix græca) It 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 – removing turpentine. It has a lightly resinous smell rather than a pine scent, but it can be used wherever pine resin is needed when making incense. It is frequently used in the cosmetic and pharmaceutical industries and is a component of many polishes and varnishes.
