copaline

{{Short description|Partly mineralized tree resin}}

Copaline (or copalite), also termed fossil resin or Highgate resin, is a naturally occurring organic substance found as irregular pieces of a pale yellow colour, for example 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.{{EB1911|inline=1|wstitle=Copalite|volume=7|page=94}}

Copaline is copal that has been partly mineralised.[http://www.webster-dictionary.org/definition/copaline WordNet Dictionary (derived from the Webster's Revised Unabridged Dictionary (1913 version) by the C. & G. Merriam Co. Springfield, Massachusetts, USA).]
