How does gypsum form

Plaster of Paris is manufactured by heating gypsum at 373 – 393 K or 150° C/300° F. CaSO4·2H2O + heat → CaSO4·0.5H2O + 1.5H2O (discharged as steam) On heating gypsum at 373 – 393 K, it loses water molecules and becomes calcium sulphate hemihydrate. This product is known as the plaster of Paris.
