The effect of the method of concentrating quartz feedstock on the purity of colored glass was investigated. It was shown that concentration of Kozlovskoe quartz sand by flotation and chemical methods allowed reducing the total FexOy by 3 times and obtaining glass with spectral light transmission in the visible region of up to 84%. The color tone of the experimental glasses made from initial and concentrated sand was within the yellow region according to calculations of the chromaticity coordinates and corresponding structures in the color triangle.
