The existing processes for the industrial production of sodium silicate generally comprise: (i) a calcination of the mixture of sand and sodium carbonate at over 1100° C.; (ii) a solubilization of the sodium silicate having thus been obtained, in the autoclave at moderate pressure, i.e., 2 to 5 bars; and. (iii) a filtration.

Flame Fusion. 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.
