using high temperature and a large air flow, the blast furnace is the perfect addition to an industrial settlement.
large and grandiose, it is able to process high quantities of iron ore into iron with the aid of a refined fuel (coke or charcoal).
(…thus sidestepping the primitive and longer ore-bloom-iron making process)
optionally, lime can also be added to the furnace to produce a higher yield.
