manufacturing process of gypsum plaster

Process involved in manufacturing Gypsum plaster -

Gypsum plaster process varies according to the method of production. Plaster takes up simple processing and burning techniques along with the varying amount of hemihydrates, ash, and anhydrite with some sand, silt and clay. Gypsum sets very easily when mixed up with water. The only small amount of water should be mixed and use it immediately. Otherwise, the gypsum plaster will become
