Quartz, sand, flint, and many other minerals are the principal sources of silica, or SiO2, a white or colorless crystalline substance. Silica is a crucial component used to create a wide range of products. The mineral containing the most silica is quartz. Pure quartz is translucent and without colour. Most igneous rocks as well as virtually all metamorphic and sedimentary rocks contain it. It is a constituent of several industrial materials.
