This allows the cylinder on reheating to flap open.
Cylinder blown sheet glass.
By the 18th century quality was often very good with an almost unmarked fire finished surface.
They supply the following glasses cylinder blown type nr no ream for late 17th century to early twentieth century and baltic type lr low ream for 16th century or earlier and vauxhall glass slightly curved to give the appearance of crown glass.
Period style window glass.
Glass can be supplied in stock sheet sizes to be cut by the glazier or cut by us to the final size.
Crown was the preferred choice for window glass together with some imported cylinder glass until the mid 19th century.
From the mid 1800 s until the early 1900 s the preferred method was mouth blown cylinder glass.
Crown glass is one of many types of hand blown glass.
Georgian and victorian sheet is a lower cost alternative where no original glass remains.
This is then rolled to give a flat piece of glass which is cooled slowly to toughen it and remove internal stresses.
This is similar to cylinder blown sheet type nr but during the final process the glass is slightly curved to give the bulging appearance of crown glass.
This process was known as crown glass and it resulted in glass that was heavily distorted and very small in size.
Stock sheet sizes of cylinder blown sheet do vary due to to the method of manufacture.
Cylinder glass is handmade using traditional mouth blowing methods.
The glass was mouth blown into cylinders and then flattened into sheets by hand.
This is similar to cylinder blown sheet type nr but during the final process the glass is slightly curved to give the bulging appearance of crown glass.
Because crown glass is no longer made we have produced a variant of cylinder blown glass called vauxhall glass.
This is a lower cost alternative for complete glazing of windows or a facade where no original glass remains and the fine quality of a handblown glass is not required.
A similar process to broad sheet except that larger cylinders are produced by swinging the cylinder in a trench.
Cylinder blown sheet is a type of hand blown window glass it is created with a similar process to broad sheet but larger cylinders are produced by swinging the cylinder in a trench the glass is then allowed to cool before the cylinder is cut.
Produced from broad sheet each sheet of glass was laboriously hand ground and polished on both surfaces.
All prices are in british pounds.
Prices may be increased if subject to abnormal currency fluctuation.
Vat charged extra to the above prices.
These glasses are designed to re create the gently wavy.
The early 20th century marks the move away from hand blown to machine manufactured glass such as rolled plate.
These methods of manufacture lasted at least until the end of the 19th century.
First a cylinder of glass is blown and then scored.
The glass is then re heated and flattened.
