A type of flat, window glass. Cylinder glass was formed by alternately hand blowing then swinging a globe of glass until a cylinder was formed that was approximately 5 feet long and 1 foot in diameter. The curved ends of the long cylinder were then cut off to form a tube that was split lengthwise, placed on a table and flattened with heat. Cylinder glass has a parallel wavy distortion due to thickness variations. Cylinder glass was made as early as the 17th century in Sunderland, England. It was less expensive than crown glass but, in general, of poorer quality.
