The setting of plaster of Paris occurs when the dry powder is mixed with water, forming a chemical reaction that causes it to harden. This process involves the rehydration of calcium sulfate hemihydrate (the main component of plaster of Paris) into calcium sulfate dihydrate. The mixture typically sets within a few minutes to an hour, depending on the specific formulation and environmental conditions. During setting, the plaster undergoes an exothermic reaction, releasing heat as it hardens.

What retardents are to slow the hardening of plaster of Paris?
