Ancient iron production

It reacted with oxygen, and generated carbon monoxide, which reduced the iron ore to iron metal. The liquefied slag separated from the ore, and was removed through the tapping arch of the furnace wall. In addition, the flux (purifying agent), the charcoal ash and the furnace lining contributed to the composition of the slag.
