Chemical bonding, a requirement for adherence, is developed at glass‐metal interfaces by achieving and maintaining equilibrium compositions at the interfaces. Reactions between iron and glasses with and without “adherence oxides” were studied by thermogravimetry, optical microscopy, and electron probe microanalysis. Adherence oxides result in the formation of alloys at the interface that tend to maintain equilibrium with the adjoining glass over an extended time and enhance atmospheric oxidation of the metal. The occurrence of dendrites in the bulk glass and the function of a “nickel flash” in porcelain enameling are discussed in terms of these reactions.
