финифть(portrait on a small opaque, usually white, enamel surface annealed to gold or copper plate and painted with metallic oxides. Since the pigments used are not vitreous enamels, this is not a true enamelling process. The metallic paints are slightly fused to the enamel surface through heating. After cooling, the completed picture is covered with a transparent vitreous enamel and heated again to give the image a glazed appearance. Britannica Alexander Demidov)
