The third step is applying color, which is known as enamel filling. The color is like the glaze on ceramics and is called "enamel". Its basic elements are boric acid, saltpeter and alkaline. Due to the differences in the added minerals, the colors differ accordingly. Usually, iron will turn gray; uranium, yellow; chromium, green; zinc, white; bronze, blue; and gold or iodine, red. The colors are ground into powder and deposited into the cells separated by filigree.

The fourth step is enamel firing, which is achieved by putting the article with its enamel filling into a kiln. Soon after, the copper body turns red, but after firing, the enamel in the little compartments will sag slightly, which will require re-filling. This process will go on repeatedly until the little cells are full.

The fifth step is polishing, which begins with emery. Polishing aims to even out the filigree and the filled compartments. The whole piece is again put into the fire and then polished once more with a whet-stone. Finally, a piece of hard carbon is used to polish the article a final time to obtain some luster on the surface.

The sixth step is gilding, which is done by placing the article in gold or silver fluid, charged with an electric current. The exposed parts of the filigree and the metal fringes of the article will again undergo another electroplating and a slight polishing.
