People ask also, what is plaster of paris Class 10? Plaster of Paris is prepared by heating gypsum to a temperature of 373K. When gypsum is heated to a temperature of 373k ,It loses three-Fourths of its water of crystallisation and forms Plaster of Paris.Plaster of Paris is manufactured by heating gypsum at 423K or 150o C/300o F. On heating gypsum at 423 K, it loses water molecules and becomes calcium sulphate hemihydrate. This product is known as the plaster of Paris. However, when water is mixed with dry plaster of Paris, it re-structures into gypsum.

How is plaster of Paris Class 10?
