Floating glass is a sheet of glass made by floating molten glass on a bed of molten metal (usually tin), although in the past metals such as lead and alloys with low melting points were used. With this method, the produced sheet has a very smooth surface and uniform thickness along its length. Today, new windows are made of floating glass, the raw material of the majority of floating glass is made of useful lime glass, but relatively small amounts are allocated to borosilicate.For information Float Glass Visit our website.
Best Float Glass Properties
In the past, glass windows were made by blowing glass bottles or lengthening glass disks. The bottles were first divided into smaller pieces, then flattened and cut from these large flat windows. Elster Pilkington is known in many credible sources as the inventor of the floating glass process.
However, this process was first recorded in 1848 by Henry Bessemer, an English engineer. For information float glass for sale Visit our website.
Float Glass Production history
After leaving the furnace, the molten glass enters a part called the tin bath and in this bath it is spread on a bed of molten tin and is stretched by the rollers at the end of the bath. This tin bath is 4 to 6 meters wide and 30 meters long to prevent the surface.
Oxygen is oxidized by oxygen in the air. A protective gas is placed on the tin bath. This gas space must be carefully controlled because its compounds can affect the contact properties of glass and tin, and this directly affects the thickness of the glass sheet.The glass floats on the tin in the form of long strips.

Since floating glass has different types, the process of producing floating glass can be divided into five general stages.
1- Raw material compounds The main components of the glass are profitable lime, 73% silica sand, 9% calcium oxide, 13% sodium carbonate, 4.% magnesium, which are carefully weighed and mixed, then added to the recycled glass (colt). The use of recycled glass reduces the consumption of natural gas, the materials are tested and stored, and they are computer controlled for the mixing process.
2- Melting of raw materials in the furnace Some of the raw materials from the mixed silos enter a five-walled furnace and melt at 1,500. C.
It can be used in precision mechanics, especially when very high surface smoothness is required, for example for visual display.
