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.
