Glass

 Glass is composed of various inorganic minerals (quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with a small amount of auxiliary materials added. Its main components are silica and other oxides. X-ray fluorescence spectroscopy (XRF) can simply and quickly analyze the composition and concentration of SiO2, Na2O, CaO, MgO, Al2O3, K2O, Fe2O3, and other components in glass samples.
