Plaster of Paris

What is Plaster of Paris? Plaster of Paris (POP) is a quick-setting form of gypsum. When gypsum is heated to about 150°C, it loses water and turns into a fine white powder, which is Plaster of Paris. It can be mixed with water to form a smooth paste that can be molded into any shape. Once it hardens, it forms a solid, durable material.

Properties of Plaster of Paris:

• Fast-setting: POP sets quickly, typically within 10-15 minutes, making it ideal for mold-making and decorative work.
• Smooth finish: When mixed and applied correctly, POP provides a smooth, fine finish, making it perfect for detailed work.
• Brittle nature: After setting, POP is hard but may be brittle, so care should be taken to prevent cracking or chipping.
• Heat-resistant: POP can withstand moderate heat, making it a good choice for applications in mold-making and sculptures.
