Float Glass Vs Plate Glass Vs Sheet Glass
At one time most of the glass manufactured in the united states was plate glass.
Float glass vs plate glass vs sheet 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. Other thicknesses are available. There are some differences between float glass and ordinary glass. It is usually about 3 32 for single strength glass.
Plate glass is generally used for large picture windows. No longer made in this country plate glass has been replaced by float glass due to the safety hazard it presents when broken and poor energy efficiency. The glass is rolled up vertically and then as it is cooling turned horizontally for further cooling and processing. However for all practical purposes i think it is fair to say that plate glass and float glass are synonymous.
Float or annealed 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. 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. The glass in liquid form was poured onto the tin causing the lighter glass to float. It provides a clear view without distortion.
Float glass is a term. A process that uses molten tin to create the surface of a glass sheet was developed in the late 1950s. The resulting product float glass had an extraordinarily smooth surface and required much less sanding than products. Sheet glass is made using a series of rollers that draws the molten glass vertically up out of the mixing tank where the glass is still a liquid.
Sheet glass is the most common glass. Float is produced by floating the molten raw material on a bath of molten tin. 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 are more common in people s lives use of float glass is widespread divided into colored glass float silver mirror white float glass windscreen level white float glass all kinds of deep processing stage float white glass scanner class white float glass coating grade white float glass mirror grade.
Oridinary flat glass and float glass are flat glass just difference from production process and quality. Sheet production virtually ended when the new float glass process was introduced in the 1970s. Plate glass was made by a process of grinding and polishing. It is usually 3 16 thick.
