Detailed explanation-1: -The main component of glass is silica (silicon dioxide) which is also present in the sand. Today, many silica-based glass types exist with different properties. Q. Glass is a homogeneous mixture of super-cooled molten sodium silicate and calcium silicate.
Detailed explanation-2: -They largely consist of silicon dioxide (silica, SiO2), but in contrast to pure silica glass (fused silica) they contain some additional substances like soda, alumina, phosphorus pentoxide, germania and potassium carbonate.
Detailed explanation-3: -The most familiar, and historically the oldest, types of manufactured glass are “silicate glasses” based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass.
Detailed explanation-4: -Glass is a homogeneous mixture of super-cooled molten sodium silicate and calcium silicate. This consists of silica sand, sodium oxide ( Na 2 O ) from soda ash, calcium oxide from limestone/dolomite, dolomite, and feldspar. More items
