champleve

The altar-frontal at Pistoja belongs to about the same period, and a little later comes the reliquary made by the brothers Arezzo, while during the whole of the fourteenth and fifteenth centuries the enamellers were kept hard at work in Italy producing objects intended for Church work in two or three distinct processes, either that called champleve, or another method, that of floating transparent enamels, known by the name of bassetaille, or still another process called encrusting.

The champleve enamel differs from the cloisonné by the small cells intended to receive the enamel not being made in the Byzantine fashion by means of strips of flat gold wire soldered to the gold plate, but by being dug out of the plate with a burin.

As we entered, I could not help being impressed by the wealth of articles in beautiful cloisonne enamel, in mother-of-pearl, lacquer, and champleve.
