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 tine  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.
