A type of black metal work, often decorated with silver or gold, that originated in India near the town of Bidar in Karnataka. Bidri metal alloy contains zinc (93.3%), copper (3.5%) and lead (3.1%). Decorative gold or silver wires and cut pieces are inlayed into into incised areas of the zinc alloy objects. The exposed alloy is then blackened by coating the piece in mud that contains ammonium chloride, potassium nitrate, and sodium chloride. Heat is sometimes applied. Finally, the object is polished with a charcoal/oil mixture. Many types of bidri objects are made, such as; vases, ashtrays, cups, boxes, and jewelry.
