Used as a desiccant due to its ability to absorb moisture, calcium sulphate is commonly found in drying tubes and packaging to protect sensitive materials from humidity. In construction, it serves as a key component in plaster, drywall, and cement, providing structure and fire resistance. It is also used in agriculture to improve soil structure and supply calcium and sulfur to crops. In food production, it acts as a coagulant in tofu making and a dietary calcium supplement. Additionally, it is used in dentistry for making dental molds and in art for sculpting and casting.
