Auxiliary flux additives to milled enamels for aluminum must serve ( a ) as an inhibitor or alkali “buffer” in enamel‐metal reactions and (b) as a flux to aid rapid enamel fusion during the early stages of firing. Raw and fritted mixtures were varied in two milled aluminum enamels. The effects of these mixtures on the physical properties, drying and firing characteristics, and water spalling resistance are tabulated. Results indicate that the proper balance between alkali, B 2 O 3 , and SiO 2 functions best to meet these requirements.
