However, the striking color of this glass, coupled with its rarity and distinctive physical characteristics means that it is a distinct sub-type of architectural glass and a character-defining feature for many historic buildings.
Blenko Glass Company began producing flat glass in 1922, but did not produce glassware until 1930. The company was founded by William John Blenko, who learned glassmaking in England.

[7] Glass was not pressed in the United States until the 1820s. [8] Until the 20th century, window glass production involved blowing a cylinder and flattening it. [9]

Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.
Cutter removing ends of cylinder and slicing the tube lengthwise Sliced tube of glass is flattened in an oven. 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.
