Until the 16th century, window glass or other flat glass was generally cut from large discs (or rondels) of crown glass. Larger sheets of glass were made by blowing large cylinders which were cut open and flattened, then cut into panes. Most window glass in the early 19th century was made using the cylinder method. The 'cylinders' were 6 to 8 ...

Cylinder blown sheet is a type of hand-blown window glass. It is created with a similar process to broad sheet, but with the use of larger cylinders. In this manufacturing process glass is blown into a cylindrical shape by a glass blower. The ends of the cylinder are cut off and a cut is made down the side of the cylinder.
Flat glass making at Blenko utilized the hand–blown cylinder glass method that was common in the 1880s. [23] During the first quarter of the 20th century, many other flat glass makers replaced well-paid human glassblowers with the Lubbers glassblowing machine. A few years later, the entire process was changed and became more automated. [24]

Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.

The early 20th century marks the move away from hand-blown to machine manufactured glass such as rolled plate glass, machine drawn cylinder sheet glass, flat drawn sheet glass, single and twin ground polished plate glass and float glass. Broad sheet glass was first made in the UK in [3] Chiddingfold, Surrey on the border with Sussex in 1226.
