Flat Drawn Sheet Glass

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.

Flat drawn sheet glass.

The belgians invented the original process but it did not reach the uk until 1919. 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. The two surfaces were of lower quality i e.

On this page please find information about our technical grade clear flat glass and microsheet materials. The glass is then annealed and cut into 7 to 10 foot 2 to 3 m cylinders. This allowed larger panes to be cut and sold. As it cooled the rising sheet stiffened and could then be cut.

This glass is still quite common in american cities. The glass was drawn vertically in a flat sheet until it cooled sufficiently to allow the glass to be cut. It offers a high optical quality that is far beyond what ordinary glass can provide. Has fire finished surfaces not perfectly flat and parallel resulting in some distortion.

Cylinders of glass 40 feet 12 m high are drawn vertically from a circular tank. This glass was drawn upward by a machine into sheets which was then cut into panes. Sheet glass has historically been used for thinner flat glass products. First developed in belgium by émile fourcault 1862 1919 fr during the early 1900s the process was used globally.

Horticultural sheet is produced by a later variation of this process. The glass is rolled up vertically and then as it is cooling turned horizontally for further cooling and processing. The fourcault process is a method of manufacturing flat glass. Technical sheet glass is fabricated by using advanced float glass processes or it is directly drawn into glass sheets.

There was great demand for glass with an enormous amount of building going in the country. The first successful method was invented by emile fourcault in belgium who took a patent in 1904. Mcgraw hill dictionary of architecture and construction. Not as smooth or uniform as those of float glass.

At the end of the nineteenth century attempts were on to draw a flat sheet of glass directly to avoid the second step of flattening the cylinder. These are cut lengthways reheated and flattened. Fourcault is an example of a vertical draw process in that the glass is drawn against gravity in an upward direction. 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.
