What is different between ordinary flat glass and float glass?
A:Both of ordinary flat glass and float glass are flat glass. Just different of production process and quality.
Raw material of ordinary flat glass is powder, quartz sand, silica sand, potassium fossils, soda, Glauber's salt,.according to a certain proportion of preparation, the high-temperature furnace melting, by vertical pulling method or a horizontal drawing method, rolling method to produce of transparent and colorless flat glass. Ordinary flat glass is divided into super rate, first-rate, second rate according to the appearance quality of flat glass. According to the thickness it is divided into 2mm, 3mm, 4mm, 5mm, 6mm.
B: Raw material of float glass is sand, quartz sand powder, sodium carbonate, dolomite. According to a certain proportion of preparation, the high-temperature furnace melting, glass liquid from the tank furnace continuous flow to and floating on the metal surface, spread into the thickness is uniform and smooth, with a fire polished glass with, cooling after hardening off from the metal liquid and then annealed cutting and colorless transparent flat glass. The glass surface is specially smooth and the thickness is very uniform, and the optical distortion is very small.. Float glass according to the appearance of quality is divided into top grade, first grade goods, qualified goods three categories. According to the thickness of 4, 5, 6, 8, 10, 12, 15, 3, 19mm nine.
C: ordinary flat glass appearance quality grade is according to the wave band, bubbles, scratch, sand, bumps, wire and other defects and determination. The grade of the appearance of float glass is based on the optical distortion, air bubble, inclusion, scratch, line, and fog spots, etc..
D: ordinary flat glass, emerald green, fragile, low transparency, the rain exposure aging deformation
Float glass, clear float glass is glass paste into the tin groove through the control gate, due to the gravity and surface tension effects floating molten tin surface, and then enter the cold trough, make both sides of the glass smooth and uniform, corrugated disappeared and finished. It is dark green, smooth surface, no ripple, good perspective, and has a certain toughness.
E: float glass and ordinary glass has different production technology.float glass has the advantages of hard surface, smooth.It has different colour with ordinary glass by side. Float glass through reflection objects without distortion, but the ordinary flat glass have watered deformation.

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 specialty borosilicate and flat panel display glass are also produced using the float glass process.
