When gypsum loses its h2o part, it kinds the mineral anhydrite (CaSO4). When anhydrite absorbs h2o it becomes gypsum. This ease of exchange is The premise of gypsum’s use in plaster. Consequently, the two minerals are very similar to each other and so are only conveniently distinguished by heating a sample within a closed tube.

In medieval Europe, gypsum plaster became a staple in building construction. Its fireplace-resistant Homes made it a useful substance for safeguarding wooden constructions from devastating fires.
Gypsum occurs in extensive beds associated with other evaporite minerals (e.g., anhydrite and halite), significantly in Permian and Triassic sedimentary formations; it truly is deposited from ocean brine, followed by anhydrite and halite. What's more, it happens in significant quantity in saline lakes and salt pans and is a vital constituent of cap rock, an anhydrite-gypsum rock forming a covering on salt domes, as in Texas and Louisiana.
The identify “gypsum” is derived through the Greek word “gypsos,” which means “plaster” or “chalk.”
