US Gypsum Plaster information

The gypsum is finely ground and the chemically-bound water is then removed through one of two calcination processes depending upon the type of plaster desired. The calcination process is one of heating the finely ground material which removes the chemically-bound water which then results in a different independent crystallline structure.
