Historically, the first method of producing fused quartz was by small-scale fusion of quartz crystals in a flame. Heraeus chemist Richard Küch first began fusing quartz rock crystal in a hydrogen/oxygen (H2/O2) flame more than 100 years ago. Heraeus has been producing quartz glass on an industrial scale with this process ever since.

polymorph of silica. At 573°C, α-quartz is transformed into β-quartz, generally similar in structure but with less distortion. This thermal transformation preserves the optical activity of quartz. Heating quartz to 867°C leads to the transformation of β-quartz into β-tridymite, involving the breaking of Si−O bonds to allow the oxygen

High grade silica is normally found in unconsolidated deposits below thin layers of overburden. It is also found as 'veins' of quartz within other rocks and these veins can be many metres thick. Silica sand deposits are normally exploited by quarrying and the material extracted may undergo considerable processing before sale.
