Color setting in the tint glass

A technique has been developed for stabilizing the optical characteristics of float glass by adding specially selected dyes to the charge, the amount of which is determined by the difference in light transmission of two samples. The difference in transmittance of the samples for each wavelength ("delta") is detected and a graph is plotted according to the wavelength. Differences in the transmission of glass samples of different thicknesses can be determined from the peaks of the "delta" curve. Il. 1, bibliography: 3 titles.
