Plaster of Paris | Resource | RSC Education

If gypsum is heated gently some of the water is lost and the crystal becomes a white powder of almost anhydrous calcium(II) sulfate (CaSO 4.1/2 H 2 O). If water is added to the cold white powder the water recombines with the calcium(II) sulfate to form hydrated calcium(II) sulfate or plaster of Paris.
