Make Window Glass
This invention revolutionized the glass industry, since until then all the glass in the window had been produced using the old glass blowing method. The glass industry in Belgium flourished as the country was the largest glass producer in the world in 1945. Founded in 1961, Glaverbel continued this pioneering role by gradually installing and expanding the first floating glass factory in continental Europe to Central Europe and Russia. Traditional window glass is not energy efficient and offers just a little more thermal insulation than anything.
To make colored window glass, powdered metals are added to molten glass, which is then formed into sheets, cut and assembled like a puzzle. Houses in the Middle Ages had windows, but for most people these windows were just a small opening to let in some light. The glass window is said to be made up of smaller pieces of glass and held together with lead pieces, similar to what was used to make stained glass in cathedrals.
One of the most common coatings results in low or low emission glass. Emissivity is the measure of how much a thermal radiation surface emits. Lowe coatings are microscopic and minimize the amount of infrared and ultraviolet light transmitted through glass. In summer, low coatings keep the refrigerator inside by protecting heat from the outside of the glass. And because low coatings also reflect ultraviolet light, furniture fades less than conventional glass.
There are several methods to make window glass, but almost all flat glass is currently manufactured using the floating glass method. Window glass is manufactured in a commercial process that uses large amounts of materials. In order to load glass and windows, the domestic demand for small thin crown glass panels was moved to large sheet metal glass. Glass plate makers were Chance Brothers from Birmingham, James Hartley and Co from Sunderland, Cooksons from Newcastle and Pilkington Brothers from St Helens. At the time of the boom in 1845, there was “a famine of sheets and glass sheets” in London because production was not kept up to date with demand.
At this point, use something called a shiny lehr to remove tension in the glass while carefully cooling it. The quality of the glass is then inspected and still cut to the correct shape so that it can be sent to the customer. Sodium carbonate (Na2CO3, “soft drink”) is a common additive and reduces the glass transition temperature. However, sodium silicate is soluble in water, so lime, a little magnesium oxide, and alumina are other common added components to improve chemical durability.
In 1989, an “invisible” tin oxide coating applied by CVD was developed that makes floating glass more energy efficient by showing visible and infrared wavelengths. Once the glass load was abolished, cylindrical glass replaced crown glass in 1845 as the preferred option for blowing most windows in the second half of the 19th century. Larger windows eliminated the need for many glazing bars and the very Victorian window cover late contained only one window. A molten glass “collection” was blown up in a balloon with a blowing pipe.
The ancient Romans made flat glass by displaying hot glass on a smooth surface. The resulting glass was not transparent or even, but was good enough to use in day windows. At that time, glass was even a great luxury and only the nobility could afford it.

The window glass can also be coated to make it more energy efficient.
