Gypsum
The word gypsum is derived from the Greek word γύψος (gypsos), "plaster". Because the quarries of the Montmartre district of Paris have long furnished burnt gypsum (calcined gypsum) used for various purposes, this dehydrated gypsum became known as plaster of Paris. Upon adding water, after a few dozen minutes, plaster of Paris becomes regular gypsum (dihydrate) again, causing the material to harden or "set" in ways that are useful for casting and construction. Five years later, the company expanded its gypsum manufacturing capabilities with the acquisition of a Las Vegas plant and gypsum quarry in Nevada. Both plants have been Company Information About PABCO Gypsum
