Inlaying is a time-honored decorative process requiring a great number of different operations, entrusted to expert hands. The piece, entirely covered in Jew's pitch, except for the motifs to be engraved, is dipped in an acid bath, then washed with petroleum, brushed, and carefully rinsed.

Two layers of gold or platinum are then applied with a brush on the deep-etched motif; the first, low assay, serves as a base, and the second, applied after firing, is made of fine, high assay gold or platinum.

Burnishing :
When taken out of the kiln after a second firing, the matte gold is sanded, then polished with agate and finally burnished with bloodstone, a semi precious stone which gives the decor great resistance and unique radiance.
