How To Make Pure Sand or Silica - thoughtco

Mix the two solutions together. The resulting gel that forms at the bottom of the liquid is orthosilicic acid. 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, SiO2, which is your pure sand.
