There are three main types of copal, golden, white and black. It originated in South America, where it is known to have been burnt by the Mayans, Aztecs and Incas as a gift to the Sun. Sometimes it is referred to as the "American Frankincense" Nowadays it is widely grown elsewhere - especially the "Golden" Copal. The best grade is generally held to be the sensual Dark Copal (Night Copal) which comes from Mexico. Also used as fossilised resin, when available.
