Most of the copper and bronze objects examined were evidently made of casting; shaping and finishing by hammering would also appear to have been practised. The mirror which is made of a low-tin bronze was probably heated and hammered after casting until it reached the atmospheric temperature; the same can be said of the celts, axes and chisels. The technique of forging was thus practised by the metal workers of Lothal.
