ORPIMENT belongs to the sulfide group. It contains arsenic and sulfur. It generally occurs in a massive form. Its color is yellow, as is the line obtained on porcelain. It is not uncommon to find a red mineral, Realgar, associated with it. This must be kept away from light, otherwise it disintegrates into a yellow powder consisting mainly of orpiment.
