Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 O). It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit.
