It is shown that colored art enamels for copper can be produced using a single low-melting glass matrix in the R2O−PbO−B2O5−SiO2 system, and that such enamels can be fired at 680–700°C. Optimum percentages of pigments and oxides are determined for coatings to have various stable colors. The synthesized enamels were tested in the manufacture of household pieces of art.
