When gypsum loses its drinking water element, it varieties the mineral anhydrite (CaSO4). When anhydrite absorbs water it results in being gypsum. This relieve of Trade is The premise of gypsum’s use in plaster. For that reason, the two minerals are similar to one another and so are only conveniently distinguished by heating a sample in the closed tube.

Hydration of Anhydrite: Gypsum also can sort through the hydration of anhydrite (CaSO₄). Anhydrite can be a calcium sulfate mineral that lacks the h2o molecules current in gypsum. When exposed to drinking water, anhydrite undergoes a hydration reaction, gypsum incorporating water molecules into its construction and remodeling into gypsum.
The diploma of dehydration depends upon the temperature and period of heating.
