Gypsum Calcining - Metallurgist & Mineral .

Calcination of Gypsum was an accidental discovery as were its rehydration characteristics. Ancient man probably used lumps of Gypsum to enclose his fire. Some degree of calcination and softening occurred and when the fire was extinguished with water he noticed the lumps soon hardened. The next step was to break the massive Gypsum into small pieces and then to pulverize them in a hollowed out ...

Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.
