What is Plaster of Paris?

Plaster of Paris is a fine, white powder made by heating gypsum to around 150°C. It is also known as calcium sulfate hemihydrate. The process of making Plaster of Paris involves the removal of water from gypsum crystals, leaving behind a powder that, when mixed with water, turns into a paste that can be molded into any shape. This paste then hardens upon drying, making it an ideal material for creating decorative features, sculptures, and even for use in construction.

Properties of Plaster of Paris

The reason Plaster of Paris is so widely used is because of its distinct properties. These include:-

• Perfect Setting Time: When mixed with water, Plaster of Paris hardens perfectly, making it ideal for applications where time is essential.
• Smooth Finish: Once set, Plaster of Paris provides a smooth, hard finish that can be painted or decorated.
• Versatility: It can be used for a variety of applications, from ceiling decorations to mold-making for sculptures and more.

Plaster of Paris vs. Gypsum Powder

While Plaster of Paris and gypsum powder may seem similar, they are not the same material. Both come from gypsum rock, but they have different properties and uses.

Differences Between Plaster of Paris and Gypsum Powder

• Processing: Plaster of Paris is created by heating gypsum to a specific temperature to remove water molecules, while gypsum powder is essentially raw gypsum that has been crushed into a powder.
• Uses: Plaster of Paris is typically used for casting and creating molds because it can set quickly and harden into a solid form. In contrast, gypsum powder is mainly used as a base material for creating drywall, plasterboard, and in agriculture for soil conditioning.
• Chemical Composition: The main difference in their chemical compositions is that Plaster of Paris is produced by heating gypsum to remove part of its water content, whereas gypsum powder retains its full water content in its crystalline structure.
