Any of several black metallic alloys of sulfur with copper, silver or lead, used to fill an incised design on the surface of another metal.
Decorative technique on metal, often silver; an engraved design is filled with a black compound of sulphur and powdered copper, silver or lead and is fixed by heating.
an inlay technique whereby the design is indented into metal and filled with a black alloy of silver, copper, lead and sulfur. After polishing, the black surface contrasts with the background.
A black alloy of silver, copper, lead and sulphur used to fill in engraving, giving an inlaid effect after being fired and polished. Used from early times, especially with Russian vessels.
A black decoration for silver objects made of copper, silver and sulfur, inlaid into engraved designs.

incised designs filled with a black enamel-like alloy
Firing an applied compound of lead, sulphur, silver and copper to produce a black shiny decoration.
A decorative black inlay used to best effect on a surface of silver or gold. A compound of sulphur combined with silver, lead and a small quantity of copper. It is fixed in place by heat.
Powdered black amalgam (silver, lead, copper, sulfur and ammonium chloride).
A form of semi-hard black decoration use on watch cases, usually silver. The design is deeply engraved and filled with a lead-oxide compound which provides a black pattern similar to inlay.
Niello is ancient technique in which an engraved design in metal is filled with powdered niello alloy (a black/dark gray metal alloy composed of silver, copper, lead, and sulphur). The niello alloy is melted (the entire metal piece is heated in a kiln) and it fuses with the underlying metal. The object is then polished - the result is an enamel-like effect. Niello has been made at least since the time of ancient Rome. In older pieces, the niello alloy fills an engraved design in metal. In newer pieces, the nilello forms the backround - the niello alloy is simply "painted" onto the metal (this process is simpler, cheaper, and less durable).
A black alloy used as a decorative inlay in metal surfaces. Made from silver, lead, copper, and sulfur.
A black metallic alloy of sulfur, copper, silver, or lead, used as inlay for an incised design on the surface of another metal. Niello refers to both the substance and the process.
Niello is a black metallic alloy of sulphur, copper, silver, and usually lead, used as an inlay on engraved metal. It can be used for filling in designs cut from metal. The Egyptians are credited with originating niello decoration, which spread throughout Europe during the Middle Ages.
