Plaster of Paris (PoP) is a commonly used name for Lime Plaster or Gypsum Plaster. The name stuck to it due to the large deposit of Gypsum discovered in Paris.
PoP is a building material that is manufactured by heating Gypsum to 150 degrees Celsius. When the same dry powder is mixed with water, it re-forms into Gypsum and remains in a soft form for some time. In this form, it can be easily given any shape by using the right tools. Even after it solidifies, it lacks the strength of cement. These characteristics make PoP an ideal finishing substance rather than a construction input.
