Glazes Crystallising

During the long history of ceramics, enamels crystallising have appeared relatively late, since they are the result of a technique particularly difficult to achieve.

The first examples of crystallizing enamel, with a few “random appearances” in Chinese ceramics, appear to be those of the National Porcelain Manufactory of Sevres, in the 1860 period Nuveau Art is the culmination in the development of this technique, we find implemented by various porcelain factories in the countries of the North.

After this period the enamel crystallising not appear until 1960, when a few isolated potter began to take it back in the hands of this technique, too hard and not very profitable to be exploited by big business.

The glazes crystallizing necessitates a check on the conditions of the furnace and a cure so precise in the production of parts such that it is virtually impossible to get two equal pieces.

In fact glazes crystallizing reproduce in the oven the same conditions that we find in nature in the formation of crystals, such as amethyst and topaz or in the ice crystals that form on the windows during the winter.

In our ceramics these crystals are formed, during cooking, inside the thin thickness of the enamel that covers the jar.

These crystals are composed of zinc silicate and developing practically only in two dimensions tend to take on the appearance of flowers that are arranged randomly on the surface of the object.

The best clay on which they develop these glazes is porcelain.

We use these as well as to produce fine enamel vases and decorative plates, also make jewelry in porcelaine
thus giving our original contibution to the interpretation of this beautiful and spectacular technical ceramics.
