Distribution of Temperature in Molten Masses of Coloured and Colourless Glasses

JSGT 1939 V23 T171-T196

Preliminary measurements of the cooling rates of, the different glasses showed that the coloured glasses examined had a higher radiation power than a colourless glass of similar composition. The emissivity of these glasses depends not only on their colour, but also on the concentration of the colouring agent present in the glass.
