Iron metallurgy in Africa

All indigenous African iron smelting processes are variants of the bloomery process. A much wider range of bloomery smelting processes has been recorded on the African continent than elsewhere in the Old World, probably because bloomeries remained in use into the 20th century in many parts of sub Saharan Africa, whereas in Europe and most parts of Asia they were replaced by the blast furnace
