Cathedral glass

Cathedral Glass is a glass window with a rough surface that breaks through the radiant light and provides a partial view of protection while the illumination function is preserved. Earlier, it was often thick, colored and poured and was often used for church windows .. During the Art Nouveau period, it was the preferred glass for glass domes, windows, furniture and room doors as well as orangeries. Even today, finely crafted cathedral glass an artistic material used for windows in representative environments.

The Kathedralglasscheiben now available in the glass trade have two different sides: one is fairly smooth, the other has an irregular pattern that is reminiscent of flat waves. Such discs are used in windows, although they are to let light through, but not precisely the actual view from a distance - for example in the bathroom windows or doors. Objects directly behind the glass are still quite clearly seen, the farther away they are from the glass, the more indistinct and shadowy they are.

Production

Traditionally, molten glass was poured onto a flat surface (wood or stone) and rolled flat, it took on the texture of the substrate. Cathedral glass, which is now produced using traditional methods, is known under the name Tischkathedralglas. It can be seen in its irregular structure, and small air bubbles, which can hardly be avoided in this method of preparation. The size of such discs produced is limited. The structure of the glass can be taken from the substrate or transferred from the rollers to the glass; they can also self by the temperature gradient between glass composition and substrate and the consistency of the glass caused ..

Like other ornamental glass - - Today cathedral glass is produced industrially on a rolling road: The pattern is transferred from one or more rolls on the glass. At the end of the rolling mill discs in standard sizes are truncated.
