Gypsum History

In fact, gypsum is a detrital sedimentary rock and can be found soluble in seawater. As water evaporates in parts of the sea, this material (sedimentary rock) can no longer remain soluble, some of which will inevitably become insoluble and precipitate after years of chemical reaction with decaying plants and other minerals.

Gypsum

Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
