Self-cleaning glass

This is an ordinary float glass with a special photocatalytic coating. It is produced by chemically bonding and integrating a microscopically thin surface layer onto the outside of a clean glass. The integrated coating reacts with solar ultraviolet rays, resulting in a gradual continuous decomposition of organic dirt - this process is called the photocatalytic effect.

Glass hardening speed

the time during which a change in viscosity occurs from liquid flowing (viscosity 102 Pa s) to a solid state. Several factors affect the hardening rate, of which the most important is the nature of the change in viscosity with temperature. Depending on the rate of increase in viscosity with decreasing temperature, “long” (long-hardening) and “short” (quick-hardening) glasses are distinguished. The larger the product and the smaller its surface for a given volume, the slower it cools. The greater the heat capacity and thermal conductivity, the faster it hardens.

Smalt

Smalta - colored glass of small sizes, used for mosaic work. Smalt is made of stained colored glass, gold and silver. The features of muffled smalt are the variety of colors, the special texture of the surface of their fracture, reminiscent of painted colors. Gold and silver smalt are small tiles consisting of two layers of glass pressed in a hot state, between which a piece of gold or silver is laid. In reflected light, thin sheets of gold give the impression of massive pieces of these metals. Gold and silver protected by a layer of glass can not lose their appearance for centuries. Smalt is used to create mosaic paintings of timeless painting. Due to the resistance of glass (smalt) to weathering, mosaic paintings for centuries do not lose the appearance and freshness of colors.
