Rosin, also called Colophony, and Greek pitch is a solid form of resin obtained from various species of Pine trees and some other conifers. The resin is usually produced by heating fresh liquid resin to vaporize the volatile liquid terpene components.

It is often semi-transparent and ranges in colour from black to yellow.
The commercial grades are numerous, ranging by letters from A (the darkest) to N (extra pale), superior to which are W (window glass) and WW (water-white) varieties, the latter having about three times the value of the common qualities.
