Mouth-Blown Sheet Glass

Flat glass used in windows and mosaics

Since 1893 Blenko has produced sheet glass in the ancient and traditional way. Skilled craftsmen mouth blow cylinders of glass, which have the ends removed, are scored, and then heated again. The final heating opens the cylinders into rectangular flat sheets of approximately 18 x 25 inches. To see this age-old and impressive process, visit us in Milton or see our Sheet Glass video.

Because of the non-mechanized and mouth-blown process, the sheets will exhibit artisanal features such as surface undulations, small marks and bubbles. These attributes are considered desirable aspects to the handmade nature and tradition. As an intended part of the handmade process these features do not detract from the glass’ safety or quality and are not considered defects but indications of individual craftsmanship and beauty.

Clear Sheet Glass

Clear sheets of glass are often used for window restoration and furniture replacement projects, as well as new projects referencing the historical process. These mouth blown glass sheets are handmade in the same historic process as century old originals. Any slight and subtle distortions found in the sheets mimic original glass windows as found before mechanization entered the glass industry.

Maximum size 18″x25″ (untrimmed)

Dalle De Verre

A technique developed in the early 1900’s, dalle de verre uses slabs of colored glass, broken into pieces using a hammer, then assembled – puzzle like- into patterns that are set in resin or concrete.
