Further cautioning is necessary in this regard. The ancient smelting process, which is not definitely known at present, would certainly have considerable effect of the trace element profile as proven by smelting experiments (Tylecote et al, 1977). Lead isotope correlation between ore and artifact has been successful in one case (Gale et al, 1982). Reporting failure in another case, Craddock (1985: 59) has rightly questioned that lead in the artifact could come not only from the copper ore (as presumed) but also from the flux and deliberate addition of lead during smelting.
