Silica, also known as silicon dioxide, is a mineral harvested from open pit mines in the form of quartz crystals or silica sand. This sand is then heated in the presence of oxygen and water, which creates tiny pores inside each silica granule and transforms it from crystalline silica into amorphous silica gel. This change in molecular state ...
