Macroscopic and Microscopic Variation of Ironworking in the Southern Highlands of Tanzania
Generally, there is more information and over-concentration on the macroscopic variation of African ironworking (e.g. in furnaces design), but we do not know how would this relate to microscopic data, and hence the need for this research. To examine and achieve this goal, my research focuses on the following key and specific objectives: (1) examines the nature of the raw materials especially refractoriness nature of the technical ceramics, (2) investigates how the smelting and refining furnaces were operated especially in terms of air supply, (3) finds out macroscopic as well as microscopic data on how slag was handled out during metal production process, (4) examines the reduction efficiency of the metal production processes, and (5) investigates the presence and the function of the bloom refining process as opposed to both smelting and (primary) smithing processes. With the latter, the ultimate goal is devise a method to verify whether parts of Africa really followed a three-stage ironworking process (smelting, refining, and smithing (primary and secondary)) as opposed to the well-known two-stage European ironworking process (smelting and smithing).
