Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and various low melting point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces. Modern windows are made from float glass. Most float glass is soda–lime glass, but relatively minor quantities of special borosilicate and flat panel display glass

2017年11月19日 20. Main constituent of practically all commercial glass is sand. Sand by itself can be fused to produce glass but the temperature at which this can be achieved is about 1700°C. Adding other minerals and chemicals to sand can considerably reduce the melting temperature. The addition of sodium carbonate (Na2CO3), known as soda ash, to produce a mixture of 75%

Glass’s properties can also change based on how it’s manufactured and the processes by which it’s shaped afterward. To strengthen glass, manufacturers can use thermal tempering to heat and cool it rapidly. Glass can also be strengthened chemically through an ion exchange process that makes the surface of the glass tougher.
