Why is plaster of Paris named plaster of Paris?

Answer 1

ANSWERS

any of several gypsum cements; a white powder (a form of calcium sulphate) that forms a paste when mixed with water and hardens into a solid; used in making molds and sculptures and casts for broken limbs

Answer 2

Plaster of Paris is a type of building material based on calcium sulfate hemihydrate, nominally CaSO4·H2O. It is created by heating gypsum to about 150 °C. A large gypsum deposit at Montmartre in Paris is the source of the name.

Answer 3

Large deposits of gypsum were to be found just north of Paris. These were used to produce the fine white decorative plasterwork of the best houses in France. Interest was generated abroad in this new material and it became a general term for gypsum plaster. Prestia Lafage still mine and produce Plaster of Paris at Meriel just north of Paris. Whilst in the UK the best deposits are to be found at Newark in Nottinghamshire, currently mined by Saint Gobain Formula (formerly British Gypsum)

New technology has made it possible to produce Plaster of Paris by using an Autoclave instead of in open pans. The plaster produced in this way forms longer crystals resulting in a substantially harder and denser material known as an alpha plaster. This is blended with the normal (beta) plasters to produce many different products of varying strength and porosity. But these many products are all still Plaster of Paris

Answer 4

Plaster of Paris got its name from a large deposit of gypsum discovered near Paris, France. When this gypsum is heated and then ground into a fine powder, it creates the plaster material known as plaster of Paris.
