The making of stained-glass windows has hardly changed since the 12th century. A stained-glass window consists of pieces of colored glass held together in a latticed web of lead. The glass has previously had details of faces, hands and drapery painted and fired on to it in black or brown paint. About the year 1300, yellow stain was discovered.  This had the ability to turn white glass yellow or blue glass green, and was extremely useful in the highlighting of hair, haloes and crowns.

Although colored glass making continued the 17th and 18th centuries, the craft declined and skills were lost. Only in the 19th century was there a serious attempt to rediscover the techniques of the medieval glazier. Men like the antiquarian Charles Winston, and the architect A W N Pugin helped to re-establish the scholarly principles for a Gothic Revival of stained glass. As a result of Winston's technical experiments of the 1850s, the quality of colored glass approached that of the medieval glaziers. Today almost all parish churches and cathedrals contain Victorian windows. Their quality and craftsmanship are now widely recognized.
