The lead binding is a technique used for centuries for large windows of churches and cathedrals and for the composition of large stained glass windows. The pieces of glass are edged with lead cames made in order to form the desired patterns on the glass. Also present in the most elegant buildings, the technique of leaded still has an antique flavor that seems to not want to ever go down. With the Art Nouveau and Liberty, the stained glass window has its great revival , developing new shapes and colors. Louis Comfort Tiffany deeply renews the stained glass window from the point of view that technical illustrations , introducing the use of opaque glass, products made by himself, and by replacing the section lead with a ribbon of copper.
Currently after a partial decay of the stained glass windows during the second postwar (in which there is primarily concern with restoration), there was a rebirth, with innovations that concern both the formal and the technical, just remember Chagall, Le Corbusier and Anzolo Fuga. After decades of bare and minimalist decor the use of stained glass to decorate houses is rapidly expanding.
The individual pieces of glass cut into the required shape for the composition, may contain various processes, such as sandblasting and painting. Special colors are designed to make fade effects and chiaroscuro in addition to the natural transparency of the glass. The more modern interpretation of the leaded glass windows wants the mixed technique as a contemporary interpretation of an ancient art. Often in leaded stain glass windows fit fused glass, engraved decorations in sand, fire and glaze painted details.
