The earliest artefacts noted so far containing zinc is from India. Lothal (2200-1500 BC) showed one highly oxidized antiquity (No. 4189) which assayed: 70.7 per cent copper 6.04 zinc, 0.9 Fe, 6.04 acid-soluble component (probably carbonate, a product of atmospheric corrosion). The material could have been prepared through smelting of zinc-bearing copper ore or the cementation route described earlier. The raw materials might have come from the Ahar-Zawar area.
