Inorganic silicates

Glass cups are usually made of inorganic silicates, after more than 600 degrees of high temperature firing, because of its chemical composition is relatively stable, so in the firing process will not produce harmful substances; Moreover, the surface of the glass is smooth and easy to clean, and bacteria and dirt are not easy to breed on the wall of the cup. The main raw materials of glass are quartz sand, carbonate, etc., which are inorganic non-metallic materials, and the main chemical components are silicon dioxide, sodium silicate and calcium silicate .
