Natural gypsum occurs in sedimentary rock formations and is mined at a nearby quarry. It comes into the mill in rock form where it is crushed and ground into a fine powder. In a process called calcining, the gypsum powder is heated to approximately 350-degrees F, which drives off 75-percent of the chemically combined water.
