Rosin Lump

Rosin Lump, also known as Greek pitch or colophony, is a solid form of resin acquired from pines and various other plants, generally conifers, produced by heating fresh liquid resin in order to vaporize the volatile liquid terpene modules. It is semi-transparent and differs in color from black to yellow. When it’s at room temperature rosin, becomes brittle. It also melts at stove-top temperature. It mainly consists of a variety of resin acids, particularly abietic acid. The term "colophony" derives from colophonia resina, which is Latin for "resin from Colophon," that happens to be an ancient Ionic city.
