Gypsum rock is converted into gypsum plaster by driving off some of the chemically combined water. Heating gypsum at 120°C for one hour results in a hemihydrate (CaSO ⁄2H 2O) with three quarters of the water removed. Gypsum hemihydrate is also known as Plaster of Paris. Prolonged heating over several hours results in the formation of
