Mines in ancient Rome gathered unprocessed metal and would then proceed to smelt it. Metal was one of the most important materials. It was used for crafts, construction, weapons, tools, and currency. Only low-status individuals or slaves worked in ancient Roman mines due to the high amounts of danger involved in their job. [36]

Natural iron ore contains various impurities in solid solution, which harden the reduced metal by producing irregular-shaped metallic crystals. The gladius was generally made out of steel. In Roman times, workers reduced ore in a bloomery furnace.
