Gum Rosin


Rosin, also called colophony or Greek pitch (Pix gr?ca), 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 temperatures. It chiefly consists of different resin acids, especially abietic acid. The term “colophony” comes from colophonia resina or “resin from the pine trees of Colophon,” an ancient Ionic city.
