Silica is the primary ingredient in the production of most glass.
A non-crystalline, frequently transparent amorphous solid used in window panes, tableware, and optics for practical, technological, and decorative purposes. some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are “silicate glasses” based on the chemical compound silica (silicon dioxide, or quartz).
Around 70% of the mix of ingredients needed to create glass is being made up of high-quality silica sand. The remaining 30% is made up of fluxing chemicals such as soda ash and dolomite, as well as a fraction of recycled glass.
