Iron Ore | HowStuffWorks

In a bloomery, the fire doesn't get hot enough to melt the iron completely. Instead, the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron.Wrought iron is hardy and easy to work, making it perfect for creating tools.
