Abstract:
     This invention relates a production method for thin colour-gathering glass with thickness below 1-7mm capable of resisting ultraviolet low visible light. The said glass may has dark green or dark grey colour. During its production, raw materials SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O3 and SO3 and their burden technological parameter fluorbaryt, mirabilite, sodium nitrate as well as corresponding colouring materials Co2O3, Fe2O3, Cr2O3, NiO, CeO2 and P2O5 are mixed respectively according to a certain proportion, stirred, and the product is made up by using "grille process" production line. Two kinds of light-gathering glass with thickness of 1.4-1.7mm and in colour of dark green and dark grey provide spectalle glass raw material for production in batch of thin sun glasses in our country.
