Sagot :
During the Iron Age the people of Africa used iron ores to
create weapons and various tools for irrigation. They put the iron ores in
blast furnaces to remove any oxygen that was present in the ore. They also used
the blast furnace to remove as much impurities as possible. The tools were also
fabricated to improve the longevity of the weapons and tools manufactured. The
iron workers were so skilled in their work that they used to travel with the
armies for creating any kind of iron weapons whenever required.
