The forced-draught (bellows-operated) shaft furnace known from\narchaeological studies is usually regarded as the pinnacle of this early smelting\ntechnology<sup>1\u20133<\/sup>. Examples of\nnatural-draught furnaces, in which gas buoyancy in a shaft of sufficient height\ninduces a draught adequate to drive the smelting process<sup>4<\/sup>, are also known, but are generally regarded as\ndisappointingly inefficient by comparison<sup>5<\/sup>. Here I report the\ndiscovery and excavation at Samanalawewa, Sri Lanka, of a previously unknown\nfurnace type. The furnaces are all situated on the western margins of hills and\nridges, where they are exposed to the strong monsoon winds. Field trials using\nreplica furnaces confirm that this furnace type uses a wind-based air-supply\nprinciple that is distinct from either forced or natural draught, and show also\nthat it is capable of producing high-carbon steel. This technology sustained a\nmajor industry in this area during the first millennium AD, and may have\ncontributed to South Asia&#8217;s early pre-eminence in steel production. <a href=\"https:\/\/www.nature.com\/articles\/379060a0\">https:\/\/www.nature.com\/articles\/379060a0<\/a><\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Ravana | Episode 01 25th November 2018\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/Ty4Bp5WUhdU?list=PLcwO5OebB2Ekp2w4ovOwVpbgVLMq01EbP\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>References<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Simulation of ancient wind-driven iron smelting furnaces of Sri Lanka<\/h4>\n\n\n\n<p><a href=\"https:\/\/www.researchgate.net\/publication\/274195582_Simulation_of_ancient_wind-driven_iron_smelting_furnaces_of_Sri_Lanka\">https:\/\/www.researchgate.net\/publication\/274195582_Simulation_of_ancient_wind-driven_iron_smelting_furnaces_of_Sri_Lanka<\/a><\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Balangoda WIND POWER early iron production SERENDIB STEEL - Dr. Jill Julef\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/SSniwMB6qkc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption> <br><strong>Balangoda WIND POWER early iron production SERENDIB STEEL <\/strong><br>(Note the wind speed)<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"headline\">Ancient Smelter Used Wind To Make High-Grade Steel<\/h4>\n\n\n\n<p>SWORDS of super-hard Damascus steel helped Islamic armies sweep west to the doorstep of Christian Europe and fight the Crusaders to a standstill nearly a thousand years ago. While researchers have long known where the steel for these weapons came from, they weren&#8217;t sure of all the techniques used in making it.<\/p>\n\n\n\n<p>Now evidence unearthed in Sri Lanka has shed new light on this early manufacturing process &#8211; and overturned some long-held assumptions. In particular, the findings indicate that the ancient metalworkers used unique furnaces that harnessed the mighty monsoon winds to produce high-quality steel on an industrial scale. Until now, experts have assumed that the steel would need to be refined through several steps. They had dismissed such wind-driven technology as impractical.<\/p>\n\n\n\n<p>Moreover, these unique devices produced in one step steel that took competing technologies several steps to refine, according to archaeologist Gill Juleff, who made the discoveries and successfully tested full-scale reconstructions. The furnaces formed the basis for an iron and steel industry on the island that reached its zenith during the first millennium AD.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.csmonitor.com\/1996\/0116\/16032.html\">https:\/\/www.csmonitor.com\/1996\/0116\/16032.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sri Lanka Raavana, the ancient Lankan monarch who is known to have excelled in technology, aviation, medicine, state craft and music.
