Dalle-de-verre

Historic England 2020 Stained Glass Windows: Managing Environmental Deterioration, Swindon, Historic England, published in 2020 defines dalle-de-verre, or prismatic glass (sometimes referred to as dalle glass) comprises: “Thick slabs of cast glass, moulded or chipped into shape with facets to refract the light, and set in concrete or resin; popular for 20th-century architecture. Also known as prismatic glass.”

It suggests that “This technique was used to form some of the most dramatic and important stained glass in the periods before and immediately after World War II, but as with all innovative systems, it can sometimes present serious conservation challenges.”

Short Guide, Scottish traditional shopfronts, published, on 18 April 2017 by Historic Environment Scotland, defines prismatic glass as: ‘Glass blocks with horizontal, triangular ribbed detail which refract light so that it is directed into a room in a predictable way. Developed by the Luxfer Prism Company, it was used in buildings before the wide availability of electricity.’
