Colemanite is a borate mineral that primarily consists of calcium, boron, and oxygen. It typically forms in evaporative environments, such as lake beds, where boron-rich waters evaporate. This mineral is often found in sedimentary deposits and is recognized for its glassy luster and white to colorless appearance. Colemanite is an important source of boron, which is used in various industrial applications, including glass and ceramics production. It is also utilized in agriculture as a micronutrient for plants. The mineral is named after the American chemist William Coleman, who contributed to its study in the 19th century.
