Art Nouveau White Lotus design. Niello is a black mixture, usually of sulphur, copper, silver, and lead, used as an inlay on engraved or etched metal, especially silver. It is added as a powder or paste, then fired until it melts or at least softens, and flows or is pushed into the engraved lines in the metal. It hardens and blackens when cool, and the niello on the flat surface is polished off to show the filled lines in black, contrasting with the polished metal around it. The contrast of the black niello against the bright silver surface produces an attractive decorative effect. Niello was used on a variety of objects over the ages, including sword hilts, chalices, plates, horns, adornment for horses, jewellery such as bracelets, rings, pendants, and small fittings such as strap-ends, buttons, belt buckles and especially on antique Pocket watch cases.
