The effect of the redox potentials of the glass batch and cullet on the dye of commercial glass containing iron oxides

The influence of the redox potentials (ORP) of charges and glass breakage on the color of glasses of industrial compositions containing up to 0.5% iron oxides has been investigated. The boundaries of the ORP values ??of the charge have been established, which make it possible to obtain glasses of green, blue-green, yellow-green and brown colors. The results obtained make it possible to predict the color and shades of glass at the stage of batch preparation. Tab. 1, ill. 2, bibliography: 4 titles.
