Abstract
The chemical measurement of the iron oxide present in the enamel was not in agreement with the iron oxide content calculated from diffusion profiles. This discrepancy could only be explained by assuming that a layer of iron oxide about 1 μm thick was present at the interface. An examination of the phenomena associated with this type of enamelling, the constant rate of oxidation and the saturation of the enamel at the glass/steel interface, has led to the conclusion that such an oxide layer must be present.
