The disadvantage of the known glass is that it has a high surface tension of 515.53 erg / cm, which does not accelerate penetration and clarification of the glass mass. The known glass should be at a maximum temperature of at least 5-6 hours. full clarification. When this occurs, some of the oxide is removed from the top layer of glass mass, which leads to a displacement of the composition. When compiling the charge, volatilization must be taken into account and a known amount of components must be introduced, since a large loss of some dye oxides leads to a decrease in the lighting characteristics of glassware.

Said glass is distinguished by a high chemical resistance and is intended for the manufacture of facing tiles by rolling. Due to the rapid increase in viscosity in the range of production, it is not suitable for the manufacture of lighting and decorative items in sensory and press-blowing methods.

The purpose of the invention is to reduce viscosity in the working temperature range.

The chain is achieved by the fact that colored glass, including SiOj, AlgO, VLO, PgOy CaO, ZbO, NagO, dye — at least one oxide and the groups:, CoO, CuO, FejO-j, additionally contains Mpb in the following ratio of components, wt.%:

The introduction of MPO in an amount of 0.1-4% contributes to the rate of decrease. viscosity in the working temperature range. This property makes the glass longer and allows it to be made of it by hand or by press-blow molding.

The proposed does not require additional heat treatment (in comparison with the prototype, where the pick-up temperature is indicated), since the layers are stratified in the process of making and the product is turned out to be jammed. An electron microscopic study showed an amorphous glass droplet structure, the droplet size varying from 0.1 to 0.3 µm, and the amount of droplet phase is 30-60%.

The compositions of glasses and their properties are shown in the table.

Raw materials are used to melt glass: sand, soda, alumina, boric acid, or borax. 3 potash or saltpeter, superphosphate ,. zinc white, pyrolusite, chrome crocus, colorants CoO, CuO, NiO, Glass is processable and boiled with lAAO-tASO C depending on the composition. Cooking is carried out in a sectional fiery furnace with a periodic effect with the capacity of AOO kg glass mass. The temperature-10 of the production cycle is 1240-1270 s, the annealing temperature of the products is 550580 ° C. The proposed colored glass can be used for the manufacture of lighting, decorative, as well as artistic products. From this structure, you can make products of any size and configuration, for example, caps, by pressing and blowing in blows. ceiling lamps and stands for lamp ng, lighting fixtures and electric glass, vases, household items and decorative glassware for interiors of housing and public buildings. Only one wall of products can vary from 1.5 to 7 mm. ; The expected economic effect is 48 thousand rubles. in year.
