Measurements of an over‐all heat‐transmission coefficient for several commercial amber glasses were carried out in a pilot‐scale furnace at temperatures of the melting range. The data obtained were used in deciding depth and insulation of tank furnaces. It appears that the transmission of light of amber glasses in the near‐infrared range gives a practical indication of these heat‐transmission properties. The same pilot‐scale furnace was used to investigate the effect of chromium oxide, nickel oxide, and iron oxide on the over‐all heat‐transmission coefficients of green glasses. An empirical equation was derived, relating the heat‐transmission coefficient to the concentration of the coloring oxides. Of the three oxides, the effect of the nickel oxide on heat transmission is the strongest and the effect of the iron oxide is the weakest.
