Sheet glass has historically been used for thinner flat glass products.
Flat drawn sheet glass.
For modern architectural and automotive applications the flat glass is sometimes bent after production of the plane sheet.
The glass is then annealed and cut into 7 to 10 foot 2 to 3 m cylinders.
On this page please find information about our technical grade clear flat glass and microsheet materials.
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.
Fourcault is an example of a vertical draw process in that the glass is drawn against gravity in an upward direction.
Has fire finished surfaces not perfectly flat and parallel resulting in some distortion.
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.
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.
This glass was drawn upward by a machine into sheets which was then cut into panes.
It offers a high optical quality that is far beyond what ordinary glass can provide.
Mcgraw hill dictionary of architecture and construction.
As it cooled the rising sheet stiffened and could then be cut.
Around the same time two methods for sheet glass drawing were developed in america.
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.
This allowed larger panes to be cut and sold.
It also allowed for much larger production.
Not as smooth or uniform as those of float glass.
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.
This glass is still quite common in american cities.
Horticultural sheet is produced by a later variation of this process.
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.
Cylinders of glass 40 feet 12 m high are drawn vertically from a circular tank.
The glass is rolled up vertically and then as it is cooling turned horizontally for further cooling and processing.
Machine drawn cylinder sheet was the first mechanical method for drawing window glass.
The fourcault process is a method of manufacturing flat glass.
The two surfaces were of lower quality i e.
The belgians invented the original process but it did not reach the uk until 1919.
