text: The smelting process was often carried out away from the rest of the community. Ironworkers engaged in rituals designed to encourage good production and to ward off bad spirits, including song and prayers, plus the giving of medicines and sacrifices. The latter were usually put in the furnace itself or buried under the base of the furnace. Examples of these date back as far as the early Iron Age in Tanzania and Rwanda (Schmidt 1997 in Childs et al., 2005 p. 293).
  Some cultures associated sexual symbolism with iron production. Smelting was integrated with the fertility of their society, The production of the bloom was compared to human conception and birth. There were sexual taboos surrounding the process. The smelting process was carried out entirely by men and often away from the village. For women to touch any of the materials or be present could jeopardise the success of the production. The furnaces were also often adorned to resemble a woman, the mother of the bloom.
