Why is the mineral gypsum used in making sheetrock?
Gypsum is used in making sheetrock because it is a soft mineral that can be easily ground into a powder, which is then mixed with water to form a paste that hardens into a solid when dried. This makes it an ideal material for creating the core of sheetrock, which is then covered with paper to create a smooth surface for walls and ceilings. Additionally, gypsum is non-toxic, fire-resistant, and has good soundproofing properties, making it a popular choice for construction materials.
