Русский “Melting”. So the concept of “fusing” is translated from English. They started talking about him in the 1990s. The rumor went from Germany, where a stained-glass window made using the fusing technique appeared. Photos of the product can be found on the Internet. The picture shows that the attraction is different from the classic stained-glass windows that were invented in the 1st century BC. We will find out how the works of glass art of the past and present differ.
The fusing technique is characterized by direct fusion of colored glass pieces. In the stained glass windows of the past, they were laid in a metal frame. Reminds cloisonne enamel in jewelry. The mass of remelted silica is attached to the piers of precious or bijouterie alloys. This allows you to work at a temperature of about 800 degrees. Glass for fusing is sintered at almost 1000 degrees. Color fragments should connect directly, become one. For this, the composition of the pieces is laid out on a backing sheet. It is also glass, produced using the technology of “float”. A sheet is formed on a tin melt. The metal floats in a bath with a protective layer of a mixture of hydrogen and nitrogen. There the molten glass enters, spreading over the tin pillow in an even, thin layer. It remains to cool.
Float glass is colorless, colored. Color is added superficially, or in the process of preparing the mass. In the latter case, the substrate is stained throughout its thickness. The glass used for the drawing can be any. Even bottle fragments are used. Only the coefficient of expansion of the material is important. The indicator is indicated by numbers with the letters SOE. Fusing stained-glass windows are made of glass with a mark of 90 and above. The first company specializing in the production of such was Bullseye. This is an American company. Specialization of the company in fusing gave the world a compatible glass. Third-party firms began to echo. They produce “one blood” samples suitable for each other during sintering.
