ONE:"But the artists do not confine themselves to porcelain; they do a great deal of enamelling on metal, and some of their productions in this way are quite as interesting as their enamelling on porcelain. They did not invent the art, so it is said, but borrowed it from the Chinese, who had in their turn borrowed it from Persia or some other of the Central Asiatic countries. Some of the Japanese artists claim that the art was borrowed from their country, but the most of those who have studied the subject say that this claim is incorrect. But no matter who invented the process,[Pg 246] it is very beautiful and is of great antiquity; it is capable of a great many variations, and, although it has been in use for centuries, hardly a year passes without some improvements in it. In making the metal enamels the strips of brass are soldered to the surface and the cavities are filled up with the liquid coloring. The whole is then baked as in the porcelain process, and the surface of the work is carefully polished until all the lines are fully developed and the completed article shines like glass.
