This brief review of the glass is considered as a product of glass obtained by melting in a glass furnace a mixture of soda, lime and silica sand. There are quartz, optical and chemical laboratory. As building material since ancient times used silica. For the construction industry is flat glass predetermined characteristics. Change of constituents for the manufacture of glass allows you to change properties of the resulting products in a wide range. Maybe change the parameters such as: Light transmission, color, thermal stability, chemical resistance, reflectivity, Heat-reflecting properties; Texture surface and other properties of sheet glass produced improved by combining with other materials. So when you turn on a metal grid to get a lot of wired glass and conductive glass. When applied to surface receive special coatings such new features as self-cleaning glass, protection from solar radiation, samozatemnenie. Filed under: Rob Daley. For example, even now preparing to launch of smart-glass, which changes its optical properties under an electric current: depends on the electric signal, it can be transparent or opaque. The thickness of commercially available sheet glass can be from 1 mm to 20 mm or more. Thick glass used in glazing if necessary to achieve high insulation and strength. In the present now, gost 111-2001 on float glass window made conditional division into grades of glass from the M1, M4 to M7, M8. The smaller non-destructive flaws in the glass, that is, the purer the glass, the lower figure after the "M". Development of technology enabling it to use glass as solar panels, heaters, screens, etc.
