Gypsum

Gypsum is a soft, naturally occurring mineral composed of calcium sulfate dihydrate. It forms through evaporation of mineral-rich water and appears as white or colorless crystals, often with a glassy or silky luster. Gypsum is commonly used in construction, most notably in drywall or plasterboard for walls and ceilings. It also has applications in agriculture to improve soil health, in sculpture and art, and as a filler in some products. Its ability to hydrate and dehydrate makes it valuable in various industrial processes, and its softness allows it to be easily shaped and cut.
