Copal Resin Specimen.
Copal Resin Specimen.

Copal is a fossilized organic resin. This amorphous yellow-to-brownish material is often confused with amber, but amber is much older than copal. A test using acetone can separate amber and copal – copal will react immediately while amber will take longer to be affected.
