Once the desired form is obtained, glass is usually annealed for the removal of stresses and to increase the glass's hardness and durability. [116] Surface treatments, coatings or lamination may follow to improve the chemical durability ( glass container coatings, glass container internal treatment), strength ( toughened glass, bulletproof glass, windshields [117]), or optical properties ( insulated glazing, anti-reflective coating).

Following the glass batch preparation and mixing, the raw materials are transported to the furnace. Soda–lime glass for mass production is melted in glass melting furnaces. Smaller scale furnaces for specialty glasses include electric melters, pot furnaces, and day tanks. [76] In a world filled with the buff, brown and sand hues of more utilitarian Late Bronze Age materials, glass — saturated with blue, purple, turquoise, yellow, red and white — would have afforded the most striking colors other than gemstones, says Andrew Shortland, an archaeological scientist at Cranfield University in Shrivenham, England. In a hierarchy of materials, glass would have sat slightly beneath silver and gold and would have been valued as much as precious stones were.

Though much is still mysterious, in the last few decades materials science techniques and a reanalysis of artifacts excavated in the past have begun to fill in details.Glass Online: The History of Glass".

Today, glass is ordinary, on-the-kitchen-shelf stuff. But early in its history, glass was bling for kings. Klement, W. Jr.; Willens, R.H.; Duwez, Pol (1960). "Non-crystalline Structure in Solidified Gold-Silicon Alloys". Nature. 187 (4740): 869. Bibcode: 1960Natur.187..869K. doi: 10.1038/187869b0. S2CID 4203025. Unlike today, glass of those times was often opaque and saturated with color, and the source of the silica was crushed quartz pebbles, not sand. Clever ancients figured out how to lower the melting temperature of the crushed quartz to what could be reached in Bronze Age furnaces: They used the ash of desert plants, which contain high levels of salts such as sodium carbonate or bicarbonates. The plants also contain lime — calcium oxide — that made the glass more stable. Ancient glassmakers also added materials that impart color to glass, such as cobalt for dark blue, or lead antimonate for yellow. The ingredients melded in the melt, contributing chemical clues that researchers look for today.

Late in the 17th century Bohemia became an important glass-producing area, and it remained important until early in the 20th century. By the 17th century England was making glass in the Venetian tradition that was notable for its simplicity. The glassmaker George Ravenscroft discovered about 1675 that the addition of lead oxide to Venetian-type glass produced a solid, heavier glass. Lead crystal, as it was known, thereafter became a favourite type of glass for fine tableware.On the positive side, programmes allow you to “Play from start” if you come in halfway through and you also get some, albeit not all, of the fancier features from Sky Q’s sports channels, including the ability to catch up with highlights while you’re watching.
