Geology and Mineralogy. Gypsum (CaSO 4 •2H 2 O), calcium sulfate dihydrate, has the unique property of releasing 1.5 molecules of water when heated to about 320-350 o F. The resulting chemical compound, calcium sulfate hemihydrate (CaSO 4 •½H 2 O) will, in turn, react with water to reform gypsum. This property is the basis for gypsum's ...
