How to Make Pure Sand (Silicon Dioxide) in a Lab
Make Pure Sand. Mix together 5 ml sodium silicate solution and 5 ml water. In a separate container, use a glass stirrer to mix 3.5 grams sodium bisulfate into 10 mL of water. Keep stirring until the sodium bisulfate dissolves. Mix the two solutions together. The resulting gel that forms at the bottom of the liquid is orthosilicic acid.

How silicon is made
The type of furnace now used to make silicon, the electric arc furnace, was first invented in 1899 by French inventor Paul Louis Toussaint Heroult to make steel. The first electric arc furnace in the United States was installed in Syracuse, New York in 1905. In recent years, furnace technology, including the electrodes used for heating elements, has improved.

How sand is made
Sand was used as early as 6000 B.C. to grind and polish stones to make sharpened tools and other objects. The stones were rubbed on a piece of wetted sandstone to hone the cutting edge. In some cases, loose sand was scattered on a flat rock, and objects were rubbed against the sandy surface to smooth them. The first beads with a glass glaze appeared in Egypt in about 3,500-3,000

What Is Silica Sand & How Is It Different From Regular Sand?
Silica sand (often called industrial sand when used for this purpose) is the main structural component in a number of construction products. Flooring, mortars, cement, roofing shingles, asphalt, and other industrial materials all use silica to improve durability and structural integrity. As silica is resistant to weather, wear and corrosion, it is often used as a caulk or sealant.
