The Blue Diamond gypsum plant of Certain-teed Corporation makes drywall, a major component of modern commercial and residential construction. Originally this was a gypsum mine, but I don't know whether mining still takes place or the deposit has been fully worked. Gypsum rock is crushed and heated to drive off the water, then reduced to a powder of calcium sulfate (also known as plaster of Paris). Drywall is made by recombining the plaster with water in a slurry then feeding it between two layers of paper. The plaster dries and hardens and binds to the paper. Finished boards are cut and dried.
