Colour And Spectral Transmittance Of Amber Bottle Glass

Because of increased interest in colour uniformity among iron-sulphur amber bottle glasses, a study was undertaken of their colour, their spectral transmittance, and the relationship of these properties. It was found that the psychophysical attributes of colour (CIE system) as computed from complete light-transmittance spectra can actually be estimated for iron-sulphur amber glasses with good accuracy from transmittance at only two suitable wave lengths, 550 and 650 mu.
