Silica Sand - an overview ScienceDirect Topics

2012-9-4  Glass is manufactured by heating a mixture of silica sand and various metallic oxides/carbonates together in a furnace to a smooth and bubble-free melt at ∼1500°C. The usual glass used in the construction industry is soda glass. Formulations are very variable but typically might be: SiO 2. 70–75%. Na 2 O.
