Gum rosin also called
colophony, 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.
Gum rosin is an important
raw material for the manufacture of adhesive, coating, inks,
rubber, soaps, paper etc.
