We have considered the influence of the structure of the bath lining on the thermal uniformity index of the colored glass melt in the feeder channel. It was found that with a thermal resistance of the bottom of 3.12 (m•K)/W and walls of 3.49 (m•K)/W of the bath, the homogeneity of the melt reaches 95.91 %. This level of uniformity meets the technological requirements for the operation of the feeder channel.
