Float Vs Sheet Glass

Float glass is a term.

Float vs sheet glass.

Oridinary flat glass and float glass are flat glass just difference from production process and quality. Plate glass was made by a process of grinding and polishing. Float glass is a sheet of glass made by floating molten glass on a bed of molten metal typically tin although lead and other various low melting point alloys were used in the past. Modern windows are made from float glass.

Sheet production virtually ended when the new float glass process was introduced in the 1970s. Most float glass is soda lime glass although relatively minor quantities of specialty borosilicate. Flat glass is a broad term that covers everything from float glass sheet glass and patterned glass rolled glasses to plate glass.

A process that uses molten tin to create the surface of a glass sheet was developed in the late 1950s. Although the plate glass process was replaced by the float glass method in the 1960s people still tend to refer to a large flat pane of unstained glass as plate glass. Float glass also called as flat glass is annealed glass not tempered or heat strengthened and is produced by controlled cooling to prevent residual stress in the glass. No longer made in this country plate glass has been replaced by float glass due to the safety hazard it presents when broken and poor energy efficiency.

Flat glass stands in contrast to container glass used for bottles jars cups and glass fibre used. Plate glass flat glass or sheet glass is a type of glass initially produced in plane form commonly used for windows glass doors transparent walls and windscreens for modern architectural and automotive applications the flat glass is sometimes bent after production of the plane sheet. Float is produced by floating the molten raw material on a bath of molten tin. Then it was left to cool.

Float glass is high quality like sheet glass with good optical clarity like plate glass and can be cut drilled machined edged bent and polished. At one time most of the glass manufactured in the united states was plate glass. Large sheets of glass for storefronts and shop windows were made this way and the same technology was used to make mirrors. Ordinary flat glass is made of quartz sandstone powder silica sand potassium fossil soda ash glauber s salt and other raw materials according to a certain proportion of preparation melting through the melting furnace through vertical drawing method or flat pull method calendering.

The resulting product float glass had an extraordinarily smooth surface and required much less sanding than products.
