Float Vs Sheet Glass

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

Float vs sheet glass.

Most float glass is soda lime glass although relatively minor quantities of specialty borosilicate. Float is produced by floating the molten raw material on a bath of molten tin. At one time most of the glass manufactured in the united states was plate glass. 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.

Then it was left to cool. No longer made in this country plate glass has been replaced by float glass due to the safety hazard it presents when broken and poor energy efficiency. Large sheets of glass for storefronts and shop windows were made this way and the same technology was used to make mirrors. Flat glass is a broad term that covers everything from float glass sheet glass and patterned glass rolled glasses to plate glass.

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. This method gives the sheet uniform thickness and very flat surfaces. Sheet production virtually ended when the new float glass process was introduced in the 1970s. The glass in liquid form was poured onto the tin causing the lighter glass to float.

A process that uses molten tin to create the surface of a glass sheet was developed in the late 1950s. Modern windows are made from float glass. 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. 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.

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. Oridinary flat glass and float glass are flat glass just difference from production process and quality. Flat glass stands in contrast to container glass used for bottles jars cups and glass fibre used.

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.
