A study of the BaChulu furnaces in Malawi suggests that 2 to Cmeter-tall furnaces were built to smelt low-quality ores (van der Merwe and Avery 1985). These natural draft furnaces depended on wind and the draw of the tall chimneys to slowly process a large volume of low-grade ore into an adequate yield of bloom.
