Silica sand is a major ingredient in the production of glassmaking—in fact, silica is the primary component in standard glass products ranging from windows to beer bottles. The purity of the silica sand used plays a role in determining the color, strength and clarity of the final product.

Silica sand provides the essential Silicon Dioxide (SiO2) required for glass formulation, which makes silica the primary component in all types of standard and specialty glass. Though the production of glass requires a variety of different commodities, silica represents over 70% of its final weight.

The term "silica" broadly refers to the mineral compound silicon dioxide (SiO2). Although silica can be crystalline or amorphous in form, crystalline silica is more hazardous to employees. It is most commonly found in the form of quartz, but it is also found in substances such as cristobalite, tridymite and tripoli.

High grade energy is needed to transform silicon oxide into pure silicon, to be hydrated producing the silanes. One possibile way to go about this is to use photovoltaic electricity to disassociate hydrogen and oxygen from water. Those gases could then be used to process sand into pure silicon and to obtain silanes.
