A method involving induction heating was devised whereby porcelain enameled specimens were fired in gastight glass tubes in which the atmosphere could be controlled and the gases and vapors collected. The progress of the processes of oxidation of the metal and volatilization of the coating were followed by carefully weighing specimens heated under varied conditions. The results confirmed the general conceptions with regard to the effects of oxidation on enamel adherence and structure. Volatilization of the enamel was evidenced by the deposition of an extremely fine powdery material on the walls of the firing chamber which was studied by spectrographic and X‐ray diffraction techniques.
