Abstract:
A process for producing glass products, comprising the steps of: refining molten glass in a refining tank; homogenizing the molten glass from said refining tank at a predetermined uniform temperature in a homogenizing tank; and forming the molten glass from said homogenizing tank into a sheet glass in a forming unit, said refining tank being lined, at least at a wall thereof in contact with the molten glass, with a lining material for glass melting furnaces, which comprises one of platinum and platinum alloy as a base material which include osmium in an amount no more than 20 ppm, so that said wall evolves no bubbles during refining, said homogenizing tank being lined, at least at a wall thereof in contact with the molten glass, with a lining material for glass melting furnaces, which comprises one of platinum and platinum alloy as a base material which include osmium in an amount no more than 20 ppm, so that said wall evolves no bubbles during homogenization, said forming unit being lined, at least at a wall thereof in contact with the molten glass, with a material for glass melting furnaces, which comprises one of platinum and platinum alloy as a base material which include osmium in an amount no more than 20 ppm, so that said wall evolves no bubbles during forming.
