Colophony (also called gum rosin) is a dried and cleaned part of the resin obtained from pines and some other plants, mostly conifer tress. It is a brittle and transparent brownish or yellowish substance added to compositions to make them elastic. (Rosin is a specific type of resin.)

One common use for this product is adding it with beeswax and Jojoba oil to make reusable beeswax food wraps. This product can range from a powder through to large chunks which may require crushing, but this can be done with a tea towel and rolling pin, or a mortice and pestle or food processor.

Trapeze Artists and Bull Riders also use it for good grip!!

Other names for this product include Greek Pitch, Pine Rosin or Pine Resin.
