When gypsum loses its water component, it forms the mineral anhydrite (CaSO 4). When anhydrite absorbs water it becomes gypsum. This ease of exchange is the basis of gypsum’s use in plaster. Consequently, the two minerals are very similar to one another and are only easily distinguished by heating a sample in a closed tube.
