The word gypsum is derived from the Greek word gypsos which means plaster. Gypsum is a soft sulfate mineral also known as"spear stone", composed of calcium sulfate dihydrate, with the  chemical formula CaSOa2HaO. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall. Gypsum products are supplied as fine powders that are mixed with water to form a fluid mass that can be poured and shaped and that hardens in to  a rigid, stable mass. They are mostly available in powder and lumps. OMINDUSTRIES consistently focused towards developing the best quality Gypsum as per our customer needs.
