How drywall is made - material, manufacture, making, used ...

Raw Materials The primary component of drywall is the mineral gypsum. It is a light-density rock found in plentiful deposits worldwide. Each molecule of gypsum (or dihydrous calcium sulfate) is composed of two molecules of water (H 2 0) and one of calcium sulfate (CaSO 4 ). By weight the compound is 21% water, but by volume it is nearly 50% water.
