Description
Commonly found in three forms: anhydrous (Anhydrite), dihydrate (Gypsum) and hemihydrate (Plaster of Paris). Anhydrite is a colorless, inert pigment which is often used as a paper filler. Calcium sulfate dihydrate is used in the manufacture of portland cement. Gypsum is also used as a filler and pigment in paints, enamels, glazes, and paper. Plaster of Paris is used for wall plaster, wallboard, moldings, and statuary.
See more information on the pages for each form of hydration.
