Beginning with simple compositions containing only those constituents necessary to make a glass, additions were systematically made in the development and study of acid‐resisting enamels. It was found that the acid resistance depends on the proper combination of constituents rather than the presence or absence of any particular material. It was shown that all fluorine compounds are detrimental to acid resistance but experience shows that some form of fluorine is necessary to obtain good quality opacity. Smelting, if properly done, milling, and firing have practically no effect on the acid resistance.
