focused on here. This period is well-represented by a number of archaeological sites in Sri Lanka, particularly at Anuradhapura, in the island's north where excavations have found some of the earliest examples of ancient iron working, and at Tissamaharama, in the south (Fig. 1.1).

Sep 11, 2020· Evidence suggests Paleolithic people arrived in Sri Lanka about 300,000 BP, and some claim it maybe occurred as early as 500,000 BP, and in ancient times this island was a rich hunting zone for Mesolithic and early Iron Age inhabitants, right up to the Pre Anuradhapura period in 543 BC.

This technology sustained a major industry in this area during the first millennium AD, and may have contributed to South Asia's early pre-eminence in steel production. BEFORE the development of the blast furnace, iron smelting was achieved by ore reduction at temperatures below the melting point of the metal, forming an agglomerated 'bloom' of low-carbon iron and slag.

Ferrous metallurgy is the metallurgy of iron and alloys.It began far back in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from at least Greece to India, and more ...
