Silicon | Encyclopedia.com

Silicon and oxygen form silicon dioxide, SiO 2, (as known as silica). Sand is mostly silica with some contributions from shells and corals. When mixed with lime (calcium oxide, CaO), soda (sodium carbonate, Na 2 CO 3) and trace substances, then melted in a furnace, silica become the key component of glass.
