Meenakari, also called enamelling, is the art of decorating a metal surface by fusing mineral substances on it. Meenakari was introduced into India by the Mughals. The process is often applied to kundan—articles of jewellery studded with gemstones set with a layer of gold foil between the stone and the mount on one side, while the reverse is lavishly enamelled using the meena technique. A wide variety of metals is used for Meenakari designing, including brass, copper, silver and gold.
