Layman's explanation: Gypsum is based on a Greek word meaning calcined. Prior to the 19th century, gypsum was used by the Egyptians as a plaster for the Cheops Pyramid, and it was imported from France during Henry VIII s reign for work on the royal properties. The countries in which gypsum can be found are Paris, Europe, Africa, and North America. One of gypsum s main uses is as a plaster, which is often called Plaster of Paris since Paris is a large source of the mineral. This plaster is frequently used as a molding to develop artwork. Gypsum can also be mixed with lime and used as a component in floors, ceilings, and walls.
