Silica, a compound mainly made of silicon dioxide, is the mineral commonly used to make glass. It is obtained from sand and is crucial in glass production, as it provides the primary substance that forms the glass structure. Silica’s ability to form a range of glass types, including window glass, container glass, and fiberglass, contributes to its widespread use. When heated to high temperatures, silica melts and can be molded as it cools to create durable, clear materials that have numerous applications in homes and industries. Its versatility makes it a fundamental component of modern glass products.
