Flat Drawn Sheet Glass

Flat drawn sheet glass drawn glass flat drawn glass flat drawn sheet glass sheet glass fabricated by the continuous drawing of the molten glass from a furnace.

Flat drawn sheet glass.

These are cut lengthways reheated and flattened. Technical sheet glass is fabricated by using advanced float glass processes or it is directly drawn into glass sheets. The glass is then annealed and cut into 7 to 10 foot 2 to 3 m cylinders. The fourcault process is a method of manufacturing flat glass.

Fourcault is an example of a vertical draw process in that the glass is drawn against gravity in an upward direction. Not as smooth or uniform as those of float glass. The belgians invented the original process but it did not reach the uk until 1919. It also allowed for much larger production.

The glass was drawn vertically in a flat sheet until it cooled sufficiently to allow the glass to be cut. 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. The first successful method was invented by emile fourcault in belgium who took a patent in 1904. Horticultural sheet is produced by a later variation of this process.

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. Mcgraw hill dictionary of architecture and construction. This glass is still quite common in american cities. The two surfaces were of lower quality i e.

This allowed larger panes to be cut and sold. The glass is rolled up vertically and then as it is cooling turned horizontally for further cooling and processing. Around the same time two methods for sheet glass drawing were developed in america. First developed in belgium by émile fourcault 1862 1919 fr during the early 1900s the process was used globally.

On this page please find information about our technical grade clear flat glass and microsheet materials. This glass was drawn upward by a machine into sheets which was then cut into panes. Cylinders of glass 40 feet 12 m high are drawn vertically from a circular tank. For modern architectural and automotive applications the flat glass is sometimes bent after production of the plane sheet.

Glass of lower quality drawn glass was made by drawing upwards from a pool of molten glass a thin sheet held at the edges by rollers. Sheet glass has historically been used for thinner flat glass products. Machine drawn cylinder sheet was the first mechanical method for drawing window glass. Has fire finished surfaces not perfectly flat and parallel resulting in some distortion.

It offers a high optical quality that is far beyond what ordinary glass can provide.
