Copaline
From Wikipedia, the free encyclopedia
Copalite (or copaline), also termed fossil resin and Highgate resin, is a naturally occurring organic substance found as irregular pieces of pale-yellow colour in the London Clay at Highgate Hill. It has a resinous aromatic odour when freshly broken, volatilizes at a moderate temperature, and burns readily with a yellow, smoky flame, leaving scarcely any ash.
