KGS--Gypsum in Kansas--Uses and Summary

Calcining in gypsum kettles is a batch process. Ground gypsum is charged into the top of the kettle when it is at a temperature of 110° C. (230° F.). The temperature is then raised slowly until it reaches about 120° C. (250° F.), at which point the gypsum seems to boil, owing to the steam being emitted from the hydrated calcium sulfate. ...

Gypsum Calcining -

Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly.
