EFFECT OF FURNACE GASES UPON GLASS ENAMELS1

Abstract
The effect of various fuel gases of products of combustion, and pressures on bonding of ground coat, physical condition and gloss of the enamel were studied under laboratory controlled conditions to determine the comparative results of firing in open and muffle furnaces and with fuel of different sorts. The benefits of recuperation are shown to he in complete combustion rather than in excess oxygen. Very hot diluted air would increase the efficiency of either oil or gas burners and produce better enamels.
