Summary

Microscopic investigations show that enamel coatings have a structure. It is formed by melting of frit grains during firing and consists of enamel particles, refractories, and gas bubbles. The structure of a coating can be influenced in specific ways, including the properties of the frit, the grinding parameters, mill additions and firing conditions. A knowledge of these parameters and their interactions is essential for the best possible choice and preparation of enamels and is the basis of high-quality enameling.
