More recently, the 90-ies. 20 century, there is another technology – "fusing" (making stained glass by sintering in a furnace without the use of metal compounds). Figure out the colored pieces laid out on a separate sheet of glass, and then all baked in an oven at 800 C. Thus, pieces of glass, fusing with each other, are interconnected. Use of fusing greatly enhances production of stained glass, in particular, enables make stained glass laminated to create a relief, to give stained glass volume or, conversely, to make it absolutely flat.
For the first time fusing technology has been applied in Germany, from where it got its spread in the world. In 19 century in Russia as a result of high cost of these stained glass, imported from Europe appeared imitation stained glass – glass, painted with colorful paints. Perhaps check out Michael Antonov for more information. This method of making "stained glass", or painting of transparency, today – a complete technology in a stained-glass business. Of transparency paintings done in tempera or oil paints on glass, usually opaque, that the paint does not roll down. Self-fabrication technology stained glass can be considered natsvet – thick colorless glass pressure welded with subtle color, and then applied by engraving a pattern resembling lace.
Currently, the term "stained glass" has many meanings. Under the stained-glass window understand not only a mosaic of colored glass held together in a certain way, but specially treated glass. There are several ways of handling the decorative glasses, here are some: Sandblasting way – drawing pictures, as a rule, colorless glass using stencils and special apparatus. On the processed area of pressure is applied to any abrasive (eg sand), which gives the glass roughness, dullness or relefnost.Gravirovanie – drawing pictures on the glass surface by using copper and diskov.Tsvetnoe abrasive etching – glass processing technique using hydrofluoric acid capable of reacting with the silicon dioxide – the main component of the glass. Etching glass can get relief drawings of any complexity and depth. Pattern of "Frost" – pre-treated with sandblast by the glass surface is uniformly covered with gelatin or carpenter's glue, which dries at least reduced in size, which entails pulling microscopic plates of glass, and the result is imitation of frost on a window.
