Machine drawn cylinder sheet glass
A type of flat glass developed with a new technology, which was invented at the beginning of 1900s. The technology made it possible to draw molten glass directly from the melting tank. Cylinders of glass (12 m) were drawn vertically from a circular tank. The glass was then annealed and cut into 2 to 3 m cylinders. These were cut lengthways, reheated, and flattened. More or less visually disturbing ‘draw stripes’ would appear in the glass.
