What is Gypsum?
Gypsum mineral is non-toxic. It is a very common sulfate and represented as CaSO4.2H2O and chemically known as calcium sulfate dihydrate. It consists of water and calcium sulphate attached to oxygen. Gypsum is helpful to animals, humans, and plants. Calcium sulphate, generally called natural gypsum, is obtained from nature in different forms, often as dihydrate (CaSO 4 2H 2 O) and as anhydrite (CaSO 4 ), which are the result of total or partial evaporation of inland seas and lakes. Both anhydrite and dihydrate exist in nature in a variety of forms. Depending upon the types, the uses of gypsum varies.
