A powder, when mixed with water, hardens to form a stone-like investment or model material. It is composed of a hemihydrate of gypsum (CaSO4·2H2O), which differs in compression strength and expansion coefficient according to how it is treated and rehydrated. There are four classes of dental plaster, with different uses as materials for casts, impressions, or stone models, based on the differences of characteristics.
