Our cylinder glass is imported from Poland and it is manufactured using a traditional method of flat glass-making.
Cylinder glass is also known as broad or sheet glass.
The actual technique varies from country to country. It is still manufactured in three factories in Europe – Jaslo in Poland, Lamberts in Germany and St Just in France. A small amount of cylinder glass is also still being made in Blenko in the USA.
This process of making cylinder glass has survived because there is still great demand. The colour range is limitless; the glass is used in churches and cathedrals, in commercial and domestic applications, and for restoration.
Crown glass is no longer made anywhere in the world, but our Polish Cylinder glass displays similar features and is a suitable alternative.
The only traditional method of flat glass making left is the cylinder process (known as broad or sheet glass). This is now used in restoration projects that would originally have utilised crown glass.
The glass is gathered on the end of a pipe and placed on a block of hollowed-out wood. The glass is blown and then reheated. The blower swings the glass “pipe” in a vertical plane until it is elongated into a cylinder. The cylinder is then split down lengthways.
The split glass is then reheated and flattened on a smooth stone and then annealed.
This process allows the colour range to be limitless; the glass is used ecclesiastically, commercially, domestically and for restoration purposes. It is also easier to make in comparison to any of the other processes.
Heritage Double Glazed Units
All our restoration glass can be made into double glazed units. We can also provide an installation service for these units using our skilled and experienced glaziers. Please contact us to discuss your requirements.
Machine drawn heritage glass
We also stock two types of machine drawn glass made by Schott in Germany. These are produced using the Fourcault method.
Goethe – 4.5mm thick – Sheet size approx. 1500 x 2400 – colourless drawn sheet with characteristic irregular surface distortion. This glass can be toughened or laminated to meet safety regulations.
De-Rest – 3mm thick – Sheet size approx. 1000 x 1500 – colourless drawn sheet with slight irregular surface distortion. This glass can be laminated to meet safety regulations.
Tatra Glass (UK) distributes stained glass throughout the UK. We also send stained glass to customers across Europe.

The origin of glassmaking is unknown, although earliest evidence discovered by archaeologists suggests Syria as the seat of origin.
Glassmaking specifically for use in windows was widely used by the Romans who were casting glass onto a plate.
Specialisation in window glass developed in the Seine and Rhine areas of France and Germany, due to reasons of climate and increase of window space in the buildings of medieval society. Two methods were used – the cylinder method and the crown method. Eventually, other methods were discovered such as cast glass, rolled glass and sheet glass. These labour intensive methods gradually disappeared as machinery took over the role of humans, and we are left with the float process, producing perfect glass.
The only traditional method of flat glassmaking left is the cylinder process, also known as broad or sheet glass. Basically, the glass is gathered on the end of the pipe and placed on a block of wood hollowed out to the diameter required and is then blown to the required dimensions. The glass is then re-heated. When ready, the blower swings the pipe in a vertical plane and inflates the glass until it is elongated into a cylinder of the required size.
Next, a lump of molten glass is attached, and the cylinder is blown until the heated part yields it open. The cylinder is then re-heated and opened out by rotation. It is next laid on a wooden horse and detached from the pipe by the application of cold iron. It is then split down the length by cutting or the use of a hot iron.
The split cylinder is then passed into the flattening chamber re-heated and flattened on a smooth stone with the use of a “polissoir” or block of wood on the end of a rod. It is then passed into the annealing chamber.
This method of making glass may vary slightly from country to country. At present, there are three factories left in Europe – Jaslo in Poland, Lamberts in Germany and St Just in France. There is also Blenko in the USA making a small amount of cylinder glass.
This process has survived because there is still a demand for this type of glass. The colour range is limitless; the glass is used ecclesiastically, commercially, domestically and for restoration purposes. It is also easier to make in comparison to any of the other processes.
