What is glass made up of?


Of all types of glass, silicate glass is the most common and widely used. This type of glass is based on the chemical compound silica, also known as silicon dioxide or quartz. Silica is most abundantly found in sand in the form of a mineral called quartz. While silica is the main constituent of glass, other chemical compounds such as sodium oxide, sodium carbonate, and lime or calcium oxide are added to it in order to yield glass of desirable properties such as the right melting point and viscosity.

Out of all manufactured silicate glass, soda lime glass accounts for more than 90% production. It contains 75% silica, sodium dioxide, lime, magnesia or magnesium oxide, and alumina or aluminium oxide.

Soda lime glass is the glass used in architectural and automotive applications.

Ruilong offers a wide range of glass processing glass machines, such as glass cutting machine, glass washing machine, etc.
