v1.c25.s5.17

It may be noted that many Harappan and Post-Harappan artefacts contained arsenic, antimony, nickel, etc. the sources of which are not known. Specimens of löllingite (iron arsenide) were found; these were evidently used for arsenic alloying of the Harappan copper artefacts. Antimony- and nickel-bearing copper ores or ingot might have been brought from cutside the sub-continent, although the possibility of indigenous resources cannot be altogether ruled out.
