    Drywall is a common manufactured building material used globally for the finish construction of interior walls and ceilings. A drywall pa nel is made of a paper liner wrapped around an inner core made primarily from gypsum plaster, the semi-hydrous form of calcium sulfate (CaSO4.½ H2O). The raw gypsum (mined or FGD) must be calcined before use. Flash calciners typically use natural gas today. The plaster is mixed with fiber (typically paper and/or fiberglass), plasticizer, foaming agent, potash as an accelerator, EDTA or other chelate as a retarder, various additives that increase mildew and fire resistance (fiberglass or vermiculite), and water. This is then formed by sandwiching a core of wet gypsum between two sheets of heavy paper or fiberglass mats. When the core sets and is dried in a large drying chamber, the sandwich becomes rigid and strong enough for use as a building material.
