Currently, production stained-glass windows – one of the most popular areas of interior design. Stained-glass business continues to evolve, there are new manufacturing techniques of stained glass. The most common technique – classical applied in calculation manufacture of stained glass in the Middle Ages. Pieces of glass are fastened together metal broaches made of lead, copper or brass. Places pressure welded joints, the diffusion of glass and frames (glass and frame are becoming single entity).
These stained glass can be found in public places, as it is suitable for filling large spaces. If the Middle Ages served as material for lead frames, now the brass is used: as the metal it is harder and less prone to deformation than lead, particularly if large stained glass or for its manufacture uses thick glass. In the second half of the 19 th century began making stained-glass technology "Tiffany": each of the pieces wrapped in copper foil, then they are arranged in accordance with a sketch of stained glass and pressure welded together, and the location of adhesions obtained very discreet, in contrast to the classical bond fragments with a metal broach. This technique of manufacture of stained glass also allows you to use at least some arbitrarily small glass. In addition, the technique of "Tiffany" enables to produce not only flat, but the bulk stained glass, such as shades for lamps (actually, it has successfully used an American artist and designer Louis Comfort Tiffany – the creator of the same name of equipment).
