FLOAT GLASS - CLEAR GLASS

Float glass is made by melting raw materials, consisting of sand, soda ash (sodium carbonate), dolomite, limestone, and salt cake (sodium sulphate). The raw materials, referred to as batch, are mixed/blended into a furnace at 1500°C to form a large pool of molten glass. The molten glass is fed into a bath of molten tin through a delivery canal. The glass then flows out to the tin surface forming a floating ribbon with perfectly smooth glossy surface on both sides with an even thickness. As the glass flows along the tin bath, the temperature is gradually reduced from 1100°C until the sheet can be lifted from the tin onto rollers at approximately 600°C. It then passes through the lehr where it is further cooled gradually so that it anneals without strain and does not crack from the change in temperature.

All Clear Float Glass can be tempered, laminated, bent, machined and decorated.
