  • Early iron production in the Levant : smelting and smithing at .

    The use of iron in the Near East is first attested by the sporadic occurrence of iron artefacts during the Bronze Age. By the end of the Late Bronze Age, however, use of iron metal gradually increases to such a level that one can assume a reasonably regular production of iron metal from terrestrial ores by smelting. However, very few iron metallurgical workshops or installations .

  • Smelting

    Around 1540, a new type of smelting hearth, blown by a footoperated bellows, was developed on the Mendip, in Somerset. This had evolved into the orehearth, with its characteristic workstone, by 1571 or 72, when the first of them reached Derbyshire. The orehearth could be built inside a mill, alongside a stream which turned a waterwheel to ...
