Cathedral Glass

Surface structure of a Cathedral Glass The Cathedral Glass from SCHOTT is manufactured using a traditional casting process. To start with, fluid glass is removed from the kiln with an iron ladle, poured onto a steel plate and then shaped into a panel between two rollers. When the panel that is still soft leaves the rollers, it is laid onto an iron table where it is allowed to cool down until it can be shoved into an annealing furnace without losing its shape. Due to the contact it has with metal for an extended period of time, Cathedral Glass takes on its typical hammered structure on the underside, while it basically smoothes out its own upper side under the influence of surface tension. Here, squeezed areas, wrinkles and bubbles that have been rolled flat can be considered to be signs of the genuineness of this handmade glass. These glasses are mainly used for true to original restoration of church and Jugendstil windows. During the Jugendstil period, Cathedral Glass was usually the first choice for designing glass domes and windows, as well as doors or an orangery.
