Gypsum is a particularly useful processed material. Its main application is as a building material, mostly produced as so-called plaster of Paris for plastering walls and making decorative features in buildings. However gypsum also has a diversity of other uses including making writing chalk, soil conditioning for agriculture, making moulds for pottery, as an additive in the manufacture of Ordinary Portland Cement (OPC), in surgical splints, in increasing the hardness of water, as an additive in certain foods such as tofu and in some types of medicines and pharmaceuticals. Its construction uses can also include external applications, such as in making walling blocks, where the climate is generally dry and not prone to the dampness that damages common types of gypsum. Gypsum can be processed relatively simply with basic equipment and techniques as well as on a large and industrialized scale as is done in some countries such as the United Kingdom. It is made from deposits of gypsum rock or sand. Raw gypsum is heated to drive off a portion of the chemically combined water. The resulting gypsum plaster, when re-combined with water, sets like cement, only much faster.
