Terry Childs and David Killick: The volume of iron circulating through West Africa in the eighteenth century must have greatly exceeded that available three centuries earlier when Euro-African trade got underway. Smelting happened all over the place in many cultures. like the. In Africa as a whole, and in southern Africa specifically, iron smelting Although data presented here do not demonstrate that iron smelting activities caused widespread vegetation change in Central Africa, we argue that intense mining and smelting can have localized and potentially regional impacts on vegetation communities. Items in museum are often not dated either or from more One area of intense debate regarding the African Iron Age is the process in which the technology of iron smelting arrived in sub-Saharan Africa. Electric Smelting in Southern Africa Rodney Jones. topic. The two most predominant are the earth science and engineering approach â investigating the chemical and mineralogical compositions of ironâ¦ technology, long since forgotten in the West, might have been recorded then. The Berbers developed and spread iron-smelting techniques across Africa. Sub-Saharan Africa is often characterized by Europeans as a region that saw no significant technological change from the adoptions of agriculture and ironworking until the European colonization of the entire continent after 1880. "INDIGENOUS AFRICAN METALLURGY: NATURE AND CULTURES", Annu. The origins of African iron production and the nature of its spread have been active topics of debate. Scientific American is the authority on science and technology for a general audience, with coverage that explains how research changes our understanding of the world and shapes our lives. All of the archaeological sites from which these early dates have been obtained are critically examined. Iron smiths reworked the raw bloomery nodules in oxidizing, open forges. For terms and use, please refer to our Terms and Conditions The initial theory was based on an unquestioned belief of the superiority of Ancient Egypt over sub-Saharan Africa (Kense … produce for example a pattern-welded sword, a wootz blade or a Japanese katana. Thus the male smith is often considered the “husband of the forge.” Though women are involved in many aspects of the metallurgic process, they almost never work the forge. The iron smelting varied greatly in design which is now a reason why we can agree that Africa had different ways of making iron and reducing their carbon content. Smelting iron from ore by a smith family in West Africa. The iron smelting varied greatly in design which is now a reason why we can agree that Africa had different ways of making iron and reducing their carbon content. Although iron smelting ceased in Africa after the arrival of the Europeans, smithying and forging continued, thence information on the making of bellows for smithies is published intensively. elongated plates or stringers This gave rise to characteristic compositional softened the iron significantly, while distributing the remaining slag into Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, … just raise a few major points: All the specimen above are in museums Abstract. inhabitants of Germany have definitively not invented iron making and many not. That the iron smelting in the film was occurring as â¦ In the 13th and 14th centuries CE, when it was the principal city of a major state, its population exceeded 10,000 inhabitants. Abstract. For long conventional academic wisdom had it that the iron age started in southwest Asia in 1500 BC and spread to the rest of the world, including Africa, from there. Iron was believed to have been the first metal to appear in the archaeological records (Childs and Killick 1993, 320). In Africa, unlike Europe and Asia, the Iron Age is not prefaced by a Bronze or Copper Age, but rather all the metals were brought together.

The former suggests that European iron imports were on an upward trajectory; the latter points to a substantial growth of indigenous smelting. Now let's look at some particular The region in and around today’s Nigeria contains some of the highest concentrations of ancient iron-smelting in Africa (Gaucher, 1981; Darling, 1986; Okafor, 1993; Quéchon, 2000; Eze-Uzomaka, 2009; Clist 2013; de Barros, 1913).

For more than a century, beginning around 1300, Zimbabwe was the wealthiest, most powerful state in southern Africa. The iron-smelting process was widely referred to as ‘blowing the bellows’ and competent smiths were known as ‘men skilled in bellows’. By the 1920s, the majority of indigenous furnaces across Africa had ceased their output of bloomery iron, and iron production was eventually outlawed by all colonial regimes in favor of Western equivalents. unremarkable; Miller offers no pictures but a lot of drawings. available online.

Introduction The study of traditional iron-smelting practices stems from several important roots. Ethnographic, technological, and archeological research into the technological life of the Haya of northwestern Tanzania show that these people and their forebears 1500 to 2000 years ago practiced a highly advanced iron smelting technology based on … but this is open to doubt, and so are the chemical reaction equations provided. smelting of iron took place there for at least 2500 years. Springer Nature was formed in 2015 through the merger of Nature Publishing Group, Palgrave Macmillan, Macmillan Education and Springer Science+Business Media. *FREE* shipping on qualifying offers. Traditional smelting in Africa depended on the bloomery process, in which the ore must reach temperatures high enough (1100–1300 °C) to separate iron from slag .Ore smelted at such temperatures does not reach the melting point of iron, but produces a solid, spongy iron mass called the bloom. A much wider range of bloomery smelting processes has been recorded on the African continent than elsewhere in the Old World, probably because bloomeries remained in use into the 20th century in many parts of sub-Saharan Africa, whereas in Europe and most parts of Asia they were replaced by the blast furnacebefore most varieties of bloomeries could be recorded. For example, each dated sample is checked The region in and around today’s Nigeria contains some of the highest concentrations of ancient iron-smelting in Africa (Gaucher, 1981; Darling, 1986; Okafor, 1993; Quéchon, 2000; Eze-Uzomaka, 2009; Clist 2013; de Barros, 1913). other important things but nobody today gives a damn about that as far a I can Section through a Mafa iron smelting furnace in the Mandara Mountains, Cameroon, showing the length of the vertical tuyère at the beginning and end of the smelting process.
