The Gypsum stone Powder is a mineral formed by di-hidrated calcium sulphate. In its crystalline structure there are two water molecules by one of calcium sulphate. Put under calcination (120-160 ºC), it releases part of the crystal water, obtaining itself a semihydrate of calcium sulphate or “burnt gypsum”, that being mixed with water, is solidified again and crystallized, reconstituting the original rock in its natural state. The plaster is a gypsum variant, finer, white and of greater hardness than normal gypsum, employed like material of ornamentation and with other stucco additives.
