Bidriware - Hyderabad
Bidriware is an eight-stage process. These are moulding, smoothening by file and the process of designing by chisels. It is then followed by engraving using chisel and hammer where pure silver inlaying is done. It is subjected to smoothening again, followed by buffing and finally oxidising by making use of soil and ammonium chloride. Bidriware is therefore manufactured from an alloy of copper and zinc metals, in the ratio 1:16 by means of casting.
