Plaster is a pasty composition that hardens when used for drying and coating walls, ceilings, and partitions, to protect penetration of rainwater and other environmental agencies. Plaster of Paris is prepared by heating gypsum (CaSO 4.2H 2 O) to a … PLASTER OF PARIS is non-flammable and non-combustible. Plaster of Paris is a fine, white powder. Reacts exothermically but slowly … While gypsum is a hydrated salt, the plaster is the result of reformed gypsum. Preparation : Plaster of Paris is obtained by heating gypsum (CaSO 4.2H 2 O) at 373 K in a kiln. Plaster of Paris is created by heating gypsum crystals, a soft mineral made of calcium sulphate dihydrate, to turn them into a dry powder. Certain additives are added when heating. Preparation of Plaster of Paris. Plaster of Paris was first named for a gypsum deposit that was located in Paris, France. Some of the Plaster of Paris products have some (up to about 25%) limestone (ie calcium carbonate) but may not have any. Heating should be done carefully.at 373 K in a kiln. Decomposes at high temperature to generate toxic oxides of sulfur. MATERIAL SAFETY DATA SHEET SHEETROCK® Plaster of Paris MSDS #61-200-003 Page 4 of 9 STORAGE: Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities (see Section 10). PROPER OCEAN CHEMICAL ANALYSIS: By contrast here is the chemical composition of the ocean as a percentage: Chloride- 55.03%; Sodium- 30.59% 1/2 H 2 O): Chemically, Plaster of Paris is calcium sulphate hemihydrate. Has generally low chemical reactivity but can act as an oxidizing agent under extreme conditions. Gypsum is a crystalline mineral of hydrated calcium sulphate (chemical formula CaSO4 • 2H2O).
