Wootz Steel Smelting

Timeline

1. c. 300–1200South India · IndiaArtisans long-carburized local iron ore with plant-based carbon sources in clay crucibles, producing high-carbon steel ingots and forming a reproducible workshop tradition.
2. 1401–1410Malabar and Cochin ports · KeralaBetween 1401 and 1410, Wootz steel was shipped in large quantities along monsoon routes to Persian Gulf and Red Sea ports, ranking alongside spices and cotton cloth as a high-value Indian Ocean trade good.
3. 1795–1820South India and Britain · IndiaBritish scientists and engineers conducted field investigations and analyzed the composition and process of Wootz steel, advancing modern metallurgical research into the mechanisms of crucible steel.
4. 1850–1900South India · IndiaIndustrialized steelmaking and changes in trade patterns caused output of traditional Wootz steel workshops to plummet, with the craft nearly lost; only small-scale revival attempts emerged in the 21st century.
