Abstract
The variations of the color of iron glasses are due to the fluctuations in (a) concentration, and (b) oxidation-reduction equilibrium. In an experimental series, changes of these to variables were exaggerated. An increase in concentration caused a decrease in transmission and a shift to higher dominant wave-lengths (yellow), while reduction caused a decrease in transmission and a shift to lower dominant wave-lengths (blue). The changes in chromaticity were evaluated and applied to problems of control and specification. The Nickerson-Balinkin small color difference formula indicated a modification of existing specifications in transmission and dominant wavelength with tolerances equal in three color dimensions.Keywords
