(10) Protective glass (appropriate auxiliary material is added during the ordinary glass manufacturing process, which has the function of protecting personal safety by preventing the penetration of strong light, strong heat, or radiation. For example, gray – dichromate, iron oxide absorbs ultraviolet light And partially visible light; blue-green—nickel oxide, ferrous oxide absorbs infrared and partially visible light; lead glass—lead oxide absorbs X-rays and r-rays; dark blue—dichromate, ferrous oxide, iron oxide absorption Ultraviolet, infrared, and most visible light; addition of cadmium oxide and boron oxide absorbs neutron flux.
(11) Glass-ceramics (also known as crystallized glass or glass-ceramics, made by adding crystal nuclei such as gold, silver, and copper to ordinary glass, instead of stainless steel and precious stones, for radome and missile heads, etc.).
(12) Glass fibers (Fibers with a diameter of several micrometers to several thousand micrometers drawn or blown from molten glass, the same composition as glass).
(13) Glass filaments (ie, long glass fibers).
(14) FRP (reinforced plastic of similar strength to steel obtained by compounding epoxy resin with glass fiber).
(15) Cellulose paper (transparent cellulose film made with viscose solution).
(16) An aqueous solution of water glass (Na2SiO3), which is named after part of the components in common glass).
(17) Metallic glass (glassy metal, typically made by rapid cooling of molten metal).
(18) Fluorite (fluorite) (colorless and transparent CaF2, used as a prism and a light mirror in optical instruments).
