Place the orthosilicic acid into a heat-safe glass or porcelain dish and heat it over a burner flame for about 5 minutes. The orthosilicic acid dries to form silicon dioxide, SiO 2, which is your pure sand. Sand is non-toxic, but it presents an inhalation hazard since the small particles could become trapped in …

In this study, rice husk was used as a biomass raw material as a substitute for commercial silica in glass making. The mass fraction of silica in rice husk ash (RHA) derived from rice husk powder by combustion at 1000 °C for 2 h was found to be as high as 96%, comparable to that of commercial silica.
