Plaster of Paris chemical name is Calcium sulphate hemihydrate. The formula of plaster of Paris is CaSO4.1/2H2O.

Plaster of Paris is prepared from gypsum. It is prepared by heating gypsum to a temperature of 100℃(373 K) in a kiln. When gypsum is heated at 100℃, it loses 3/4 th of its water of crystallisation and forms plaster of Paris.

CaSO4.2H2O ---(Heat to 100℃)--->
CaSO4.1/2H2O + 1 1/2 H2O.

Hope it helped.
