Function of Silica (SiO2) in glass manufacturing process.
Melting Point Control: Silica contributes to the control of the glass's melting point. Pure silica has an extremely high melting point, making it difficult to work with. However, when combined with soda (Na2O) and lime (CaO), the melting point of the glass mixture decreases, making it more suitable for the glass manufacturing process.
