We are offering gypsum plaster, or plaster of paris, is produced by heating gypsum to about 300 °f (150 °c):[2]
caso4·2h2o + heat → caso4·0.5h2o + 1.5h2o (released as steam).
When the dry plaster powder is mixed with water, it re-forms into gypsum. The setting of unmodified plaster starts about 10 minutes after mixing and is complete in about 45 minutes; but not fully set for 72 hours.[3] if plaster or gypsum is heated above 392°f (200°c), anhydrite is formed, which will also re-form as gypsum if mixed with water.[4]
a large gypsum deposit at montmartre in paris led "calcined gypsum" (roasted gypsum or gypsum plaster) to be commonly known as "plaster of paris".
Plaster may also be used to create complex detailing for use in room interiors. These may be geometric (simulating wood or stone) or naturalistic (simulating leaves, vines, and flowers) these are also often used to simulate wood or stone detailing found in more substantial buildings.
In modern days this material is also used for false ceiling. In this the powder form is converted in a sheet form and the sheet is then attached to the basic ceiling with the help of fasteners. It is done in various designs containing various combinations of lights and colors.
