Cylinder blown sheet glass has been manufactured in France and Germany since the 18th Century. It began to be manufactured in the UK in the mid 19th Century, although only one small company continues manufacturing.
Machine drawn cylinder sheet was the first mechanical method for "drawing" window glass. Cylinders of glass 12 m (40 feet) high are drawn vertically from a circular tank. The glass is then annealed and cut into 2 to 3 m (7 to 10 foot) cylinders. These are cut lengthways, reheated, and flattened. This process was invented in the USA in 1903. This type of glass was manufactured in the early 20th century (it was manufactured in the UK by Pilkington from 1910 to 1933).
