Plaster of Paris (POP) is also known as Gypsum Plaster, Witch is a white powder consisting of calcium sulfate hemihydrate. The natural form of the compound is the mineral bassanite.

The name “Plaster of Paris” was given because it was originally made by heating gypsum from a large deposit at Montreal, a hill in the north end of Paris.

P.O.P in Decorative Architecture

Plaster of Paris 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.

The common use of this plaster can be seen in the construction of houses.
