Enamels on Metal. The art of enamelling on metal has been practised from very early times. In its earlier forms it was chiefly an art applied to jewellery and the ornamentation of ecclesiastical metal work. In time, however, it was applied as a convenient method of decorating utilitarian household articles such as fire-dogs and candlesticks. Those who frequent the more important museums often associate enamels with the costly and rare enamels of Limoges, and the choice bits of Italian enamels seen in the cases of metals where the most valuable curios are gathered together. Such vessels as those marvellous effects produced by the enamellers of Limoges are indeed rarely found among household curios; it is well, however, to note that the processes by which those effects were produced changed as time went on. The earlier translucent enamel of the Italian artists was laid over an incised metal ground, the design previously prepared showing through. In the later Limoges enamels the surface with which the copper base was overlaid was painted, very much in the same way as the miniature painters on enamels operated in after-years. The process of covering metal with enamels made of a species of glass is very ancient, but the basis of all enamels is the application of fusible colourless silicate or glass in pattern or design, mixed with metallic oxides, the prepared surface being afterwards fired until the enamel adheres firmly to the copper or other metal. The processes varied, but the firing or fusing was the same throughout. The name "enamel" is traceable to the French word _enail_ and the Italian _smalto_, both having the same root as the Anglo-Saxon word "smelt." The enamels of China and Japan so extensively imported into this country of late years are chiefly made by filling cloisons or cells formed of fine metal wires or plates with coloured enamels and then firing them. As the collector advances in his appreciation of the old craftsmen, he soon recognizes the difference between the antiques sent over by Oriental merchants and the modern works made on present-day commercial lines, and not the work of men whose time was deemed of small account if they acquired notoriety for the beauty of their work. The household enamels of English make consist chiefly of those beautiful little boxes, trinkets, and domestic objects made at Battersea and Bilston in the eighteenth century. The enamels used for the ground were tinted rose, blue, and other shades, and ornamented with painted pictures and mottoes. A very fine group of Battersea patch boxes is shown in Fig. 63.
