Question

in what way did iron develop the art and craft in the later vedic period

Answer 1

In the prehistory of the Indian subcontinent, an "Iron Age" is recognized as succeeding the Late Harappan (Cemetery H) culture.[1] The main Iron Age archaeological cultures of present-day northern India are the Painted Grey Ware culture (1300 to 300 BCE)[2] and the Northern Black Polished Ware (700 to 200 BCE). This corresponds to the transition of the Janapadas or principalities of the Vedic period to the sixteen Mahajanapadas or region-states of the early historic period, culminating in the emergence of the Maurya Empire towards the end of the period.

The earliest evidence of iron smelting predates the emergence of the Iron Age proper by several centuries. [3]
