This is attained levels of great mastery, leading to an artistic called «émaux mixtes» or “mixed enamel”. production of the highest quality. The decorative motifs can also be painted on a white enamel background, similar to the technique of painting on porcelain. This process, the most recent in the history of enameling, has reflected in the course of its brief existence all the discoveries made over the course of a thousand years. Enameling techniques paralleled those of painting, while con- serving their specificity. The soft colors of a face, the hazy light of a sunrise, the intensity of shadow, were all beautifully rendered by enamel, as artists such as Toutin the elder, who worked in Blois around 1625, demonstrated. Toutin, indeed, was the originator of the technique of painting on enamel. Enamel is a vitreous substance made up of sand, silica, and a mixture of potassium salt, lead, and soda, which melts at a fairly low temperature. The proportions of the mixture vary depending on the base to which it is to be applied. Without coloring, enamel is clear and transparent, and is called “flux” (“fondant” in French). Metallic oxides can be added to give it color while preserving its transparency. It can be made opaque by adding pewter oxide. Unlike paint, enamel is inal- terable and eternal. These enamels, transparent or opaque, can be applied to many materials, in- cluding earthenware, stoneware, porcelain, glass, lava, and metal (sil- ver, copper, iron, etc.). Two details of a mirror.

It world, by the Greeks, Etruscans, Phoenicians, and seems clear that the process of enameling goes back the Egyptians, as is proven by pieces found in to Antiquity. This was the opinion of La Riatère and archeological excavations. It has been argued, it is confirmed by the archaeological finds conserved however, that the material used was not enamel but in several museums. The mentions of enameling in either a kind of putty colored by vegetal or mineral literature confirm this. In the “Odyssey”, Homer extracts, or glass paste.
