Silica sands are the most widely used due to their chemical purity and advantageous thermal properties, and are compatible with all types of foundry binding systems. The density of silica is about 2.2-2.4 g/cm3 and has a high melting point, over 1690°C.
Glass. 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%.
