The traditional mbaula, or charcoal brazier, used in Zambia, has been upgraded with the inclusion of an insulating lining made of clay. A factory just outside Lusaka manufactures them, and they retail at a small premium over the regular mbaula. I first saw one of them in 2003. Because of the insulation, all the heat from the burning charcoal is directed at the pot of food, making them far more efficient for cooking; however, as the mbaula is also, for many Zambians, a source of heat in the winter, they aree not very popular.
