This type of gypsum was called Lapis Specularis ("specular stone" or "mirror stone") in ancient Rome. The transparency of this mineral is a characteristic that made it suitable for the manufacture of window panes during the Roman Empire (1st-2nd centuries AD). The main deposits of this type of gypsum are found in Spain, mainly in Cuenca (Castilla-La Mancha) and Teruel (Aragon).
