2013/10/16 3. Plaster of Paris – properties and complications. Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulphate returns to the relatively insoluble form, and heat is produced [2 (CaSO 4.½ H 2 O) + 3H 2 O → 2 (CaSO 4.2H 2 O) + Heat].
