The effect of quartz raw dressing on the optical properties of stained glass

The influence of the method of enrichment of quartz raw materials on the purity of colored glasses has been studied. It is shown that the enrichment of quartz sand from the Kozlovskoye deposit by flotation and chemical methods made it possible to reduce the total content of Fe _x O _y by 3 times and obtain glasses with spectral light transmission in the visible region up to 84%. In this case, the color tone of the experimental glasses obtained on the basis of the initial and enriched sand, according to the calculations of the chromaticity coordinates and the corresponding constructions in the color triangle, was within the yellow region.
