Cadmium-sulfur-selenium pigments are used in the manufacture of signal glasses for air, automobile and train signal lamps. These pigments are required because they produce the spectral transmittance curves in the visible light region which have been specified by the various transportation bureaux or standards committees. Once the color in terms of chromaticity coordinates has been chosen, it is the job of the ceramic engineer to produce the properly colored glass, safely and consistently. Since a very important property of the glasses is chemical durability, the leaching of cadmium and susceptibility to weathering are discussed in detail.
