Plaster of Paris

Plaster of Paris is a quick-setting material made from a fine powder called calcium sulfate hemihydrate. When mixed with water, it forms a creamy slurry that hardens as the water reacts chemically, creating a solid, durable surface. It is commonly used in construction for molding, casting, and decorative elements, as well as in medical applications like making casts for broken bones. Its ability to set quickly and create smooth, detailed surfaces makes it versatile, but it also requires careful handling because it hardens rapidly once mixed.
