Thin foils and beads of gold found at Lothal suggest that sheet-metal was beaten into foils. Casting was also widely practised. The goldsmiths must have possessed adequate skill and knowledge of metallurgy. Joining was done either by sweating or soldering. In the case of beads the midrib concealed the joints. Controlled heating was also applied for joining. The use of copper as an alloy for soldering between the spirals of coiled gold rings clearly suggest the use of an alloy. Conical objects and rings of gold were joined by sweating.
