The interaction of two elements of variable valence (As + Fe and As + Cr) has been studied in their joint presence in glasses of the four-component system K 2 O- B 2 O 3 - SiO 2 -Al 2 O 3 . It is shown that with an increase in the basicity of the glass, the element located to the left in the redox series passes into the highest valence state. Recommendations are given for adjusting the concentrations of alternating valence elements in order to optimize the color (color) of colored and colorless glasses. Tab. 5, ill. 2, bibliography: 4 titles.
