Gypsum
Gypsum is a hydrous, soft sulfate mineral, specifically a calcium sulfate dihydrate, which means it has two molecules of water in its chemical composition. This is seen in its chemical formula, CaSO 4 2H 2 0. When gypsum is heated and the water within the mineral is evaporated out, gypsum turns into a chalk or plaster, known as plaster of Paris.
