Dehydration: Rock into plaster 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 hemi-hydrate (CaSO 4.1⁄2H 2O) – with three quarters of the water removed. Gypsum hemi-hydrate is also known as Plaster of Paris.

As a consequence, gypsum typically occurs as layers associated with limestone, dolostone, shale, and rock salt. As seawater evaporates, gypsum is the first 'salt' to be precipitated, followed by anhydrite, halite, and finally sylvite. Usually found with other evaporite and carbonate minerals, such as anhydrite, calcite, dolomite, borax, and ...
