A good green colour is obtained on malleable castings by blackleading the castings, and then lacquering them, when heated, with a green lacquer. Or they may be painted over with bronze powder, which may be obtained of various colours and tints, rubbed up in best varnish, and heated in a hot japanning stove. But the best way is to have them bronzed by electro-deposit of copper, brass, or other metal; or they may be tinned in the ordinary way, and then lacquered with yellow or gold lacquer when heated in a stove or on a hot plate.
