Plaster of Paris,or simply plaster,is a type of building material based on calcium sulfate hemihydrate (gypsum),nominally CaSO4 · 0.5H2O.It is created by heating gypsum to about 150ºC.
CaSO4 · 2H2O → CaSO4 · 0.5H2O + 1.5H2O (released as steam).
A large gypsum deposit at Montmartre in Paris is the source of the name.(The place that makes this plaster originated from Paris).
