Gypsum Plasterboard and the environment GreenSpec
'Stucco' is produced by removing around 75% of the water from the gypsum through heating using natural gas to a temperature of over 150'C. This process of 'calcination' changes calcium sulphate from its dihydrate state (gypsum) to its hemihydrate state. The hemihydrate calcium sulphate (CaSO 4 .½H 2 O) is now ready to form plasterboard.

The structure of gypsum consists of layers of calcium (Ca 2+) and sulfate ( SO2− 4) ions tightly bound together. These layers are bonded by sheets of anion water molecules via weaker hydrogen bonding, which gives the crystal perfect cleavage along the sheets (in the {010} plane).
