In this process iron or steel of the required size is heated, and slightly hammered into flat surfaces on which grooves are made. A Lac base is then fixed, on which designs are drawn with a chisel. Minute bits of gold or silver threads are then hammered into them. It is rubbed again with black paint to give it a glossy effect. Wide ranges of ornamental objects are produced through this process.
Ivory is used in architectural decoration.
The wooden doors of the Bikaner palace are ornamented with ivory work. The doors of the Amber palace in Jaipur, the exquisite work of the Mysore palace doors and the doors of the Golden Temple at Amritsar, are breath- taking examples of this work. Miniature carving works of idols for worship too are done.
