The formation of the equilibrium Cu(I)↔Cu(II) in colored optical glasses under the combined action of several factors is examined. It is shown that the oxidation of copper intensifies with increasing total copper content by weight, increasing content of carbonates in the mix, and increasing basicity of the matrix and depends primarily on the ratio of chromium, arsenic, and copper oxides. Afactor is proposed for making a quantitative assessment of the combined effect of the chromium and arsenic oxides on the copper equilibrium.
