The great demand for glass for furnaces is due to its unique combination of chemical and physical properties that are not inherent in any other substance. There is no other material found for the bulb of an electric lamp that would have similar transparency, resistance to heat, mechanical strength, low cost and excellent weldability with metal products. We would not be able to invent telescopes, microscopes, cameras, video cameras, televisions and much more without glass. All of the above properties are due to the fact that furnace glass is an amorphous material and not crystalline. At standard room temperature and even at 750°F, this material does not change its physical properties. But with further heating, the glass begins to soften and becomes a viscous liquid. The charge that is used for furnace glass production consists of the following main components: quartz sand, sodium oxide and lime. Also, lead oxide, boric anhydride and many other things are added. Everything depends on what kind of final product you need to get at the output. All ingredients are mixed with strict adherence to proportions, based on a specific technological process. Nowadays, glass is no longer as fragile as it was before. There are such types of glass whose strength is not compromised in any way by steel, as well as frost-resistant and armored ones. What types of glass are used for wood stove and furnaces? Quartz glass. This material consists exclusively of silica. This furnace glass has the simplest properties. It does not deform even at a temperature of 1800 degrees. The coefficient of thermal expansion of this material is very low, and therefore it is heat-resistant. The volume and surface resistance of glass for furnace is quite large. It is capable of transmitting not only visible, but also ultraviolet rays. This type of glass is very difficult to melt and form other glass products from it. Lime glass. This glass contains additional ing... Read more
