"The oldest known substitute for amber is copal, a resin which is very similar in appearance" The term "copal" was derived from "copalli," a Spanish word meaning incense, which is what copal is used for as well as in varnish.

One test for copal vs. amber can be by applying a small drop of ether, which evaporates quickly on amber leaving it unaffected, while it makes copal and other recent resins sticky
