- Blown plate
Blown plate is one of many types of hand-blown
glass. It is made from broad sheetglass by laboriously hand grinding and polishing both surfaces. Blown plate is of a sufficient quality and size for mirrors and coach glasses.
Other methods for making hand-blown glass included:
broad sheet, crown glass, polished plateand cylinder blown sheet. These methods of manufacture lasted at least until the end of the 19th century. The early 20th century marked the move away from hand-blown to machine manufactured glass such as rolled plate, machine drawn cylinder sheet, flat drawn sheet, single and twin ground polished plateand float glass.
There is a record of blown plate being produced in
