What Is Plaster of Paris Used For?

By Alice Nichols

Plaster of Paris is a widely used material that has a variety of applications. It is a white powder made by heating gypsum, a mineral found in the earth’s crust, to around 150 degrees Celsius.

Once heated, the gypsum loses its water content and becomes a dry powder that is mixed with water to form a paste. This paste can be molded into any shape and then allowed to dry and harden.
