Making Glass with High Voltage Electricity and Sand!
Glass is made from melted and recrystallized silicon dioxide. Sand is a mixture of small pieces of weathered rock and the main component in rock (and sand) is silicon dioxide (SiO2). In fact, these two elements, silicon and oxygen, are the most abundant elements in the Earth's crust - 46.6% oxygen, 27.7% silicon.
Silica
Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2).Silicon compounds are the most significant component of the Earth's crust.
How silicon is made
Second only to oxygen, silicon is the most abundant element in Earth's crust. It is found in rocks, sand, clays and soils, combined with either oxygen as silicon dioxide, or with oxygen and other elements as silicates.
The Separation of a Mixture into Pure Substances
quite soluble in water. Silicon dioxide (sand) is a large macromolecule that is essentially insoluble in water. Benzoic acid is polar, but is much less polar than water so it dissolves in water only to a limited extent. The solubility of these three substances in water is given below. The solubility of each is expressed in
Battle of the elements: silicon builds digital revolution from sand
Meanwhile, the vast majority of silicon used in everyday life exploits its natural form, with crystalline silicon dioxide – in the form of sand and quartz – making up about 12% of the Earth's crust.

How Glass is Made | What is Glass Made of? | Corning
The sand commonly used to make glass is comprised of small grains of quartz crystals, made up of molecules of silicon dioxide, which is also known as silica. When those molecules are heated to high enough temperatures, the sand melts and loses its crystalline structure, and as it cools it gains an entirely different structure.

Silicon
Silicon is found in nature in the form of silicon dioxide (like some types of sand and many rocks). The extraction of silicon from silicon dioxide is extremely energy intensive; it requires 1000-1500 megajoules of primary energy per kilogram to process high-grade silicon for computer chips or solar panels. This is an excellent example (along with …

8.22: Silicon Dioxide
Silicon is reluctant to form multiple bonds, and so discrete molecules, analogous to, do not occur. In order to satisfy silicon's valence of 4 and oxygen's valence of 2, each silicon must be surrounded by four oxygens and each oxygen by two silicons. This can be represented schematically by the diagram
