Description
A black metallic alloy of sulfur with copper, silver or lead used to produce dark inlay designs on the surface of gold or silver. Niello is prepared by mixing a molten metal (silver, copper or lead) with powdered sulfur. The fused compound is cooled, ground to a fine powder, then mixed with water and a flux (ammonium chloride or borax) to form a paste. An incised pattern in either a gold or silver object is filled with the paste then the object is heated to produce an enamel-like black metal in the incised lines. Niello was used by the ancient Egyptians, Greeks, Romans and Persian and is still widely practiced in the Far East (Untracht 1968).
