Which mineral is a major component of glass and ceramics?

• A. Clay
• B. Silica
• C. Gypsum
• D. Calcite

Answer: (B)

Silica, or silicon dioxide, is the major component of glass and ceramics. In glassmaking, silica sand provides the essential network-forming material; when melted, SiO2 creates a continuous three-dimensional framework of linked SiO4 tetrahedra that gives glass its transparency, hardness, and chemical stability. Although other ingredients are added to lower melting points and adjust properties, silica remains the dominant constituent. In ceramics, silica similarly serves as the primary structural material that helps form durable, heat‑resistant bodies and glazes. Other minerals like clay, gypsum, and calcite contribute to different properties but don’t provide the same network-forming role as silica.
