Our church has also been provided with new cathedral glasses in the process of its renovation.
Cathedral glass is the name given commercially to monochromatic sheet glass. It is thin by comparison with slab glass, may be colored, and is textured on one side.
The name draws from the fact that windows of stained glass were a feature of medieval European cathedrals from the 10th century on-wards.
The term cathedral glass is sometimes applied erroneously to the windows of cathedrals as an alternative to the term stained glass. Stained glass is the material and the art form of making colored windows of elaborate or pictorial design.
