Cylinder blown sheet glass

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.

[1] The standard (non-Blenko) cylinder method caused surface damages on the glass due to the flattening and moving, and the sheet therefore had to be ground and polished.

The early 20th century marks the move away from hand-blown to machine manufactured glass such as rolled plate, machine drawn cylinder sheet, the Fourcault process of flat drawn sheet, single and twin ground polished plate and most common, float glass.

Cylinder blown sheet glass was manufactured in the UK in the mid 19th century.
