Complex Iron Smelting and Prehistoric Culture in Tanzania

Abstract: Western scientists and students of history have long explaind th iron bloomery process by evidence available from European archeology. 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 preheating principles and, as a result, produced carbon steel. This sophisticated technology may have evolved as an adaptation to o… Show more

“…The development of long-distance trade networks did not seem to affect the community's economic or subsistence activities to any great extent. The arrival of iron technology encouraged a rapid adoption of metal production and limited use of agriculture in many areas of Africa (Alexander, 1980;Chami, 1994;Collett, 1985;de Barros, 1997;Onyango-Abuje and Wandibba, 1979;Schmidt, 1996Schmidt, , 1997Schmidt and Avery, 1996;Schmidt and Childs, 1985;Soper, 1967b;Wadley, 1996). In other areas, such as Gogo Falls on the shores of Lake Victoria, replacement of stone with iron technology was gradual (Robertshaw, 1991a).…”

“…First, ethnoarchaeological and archaeological research in northwestern Tanzania in the late 1970s led to major rethinking of historical misrepresentations about the inferiority of African technology (Schmidt and Avery 1978). Following the announcement of these findings, an intense interest developed in official circles for popularising the relevance of science and technology in the present and future.…”

“…One example is work on the intensification of early iron production in Buhaya, Tanzania (Schmidt and Avery 1978;Schmidt 1994Schmidt , 1997. In this research, charcoal species excavated from iron smelting furnaces were used as a proxy for vegetation change through time alongside evidence from a poorly dated pollen core.…”
