Instead, theiron heatsup into a spongy mass containingironand silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into theiron metalto create wroughtiron.Wrought ironis hardy and easy to work, making it perfect for creating tools.

A development of thisprocessinvolves a rather more sophisticated furnace fed with forced air which both reduces the ore and diffuses carbon into the metal, creating castironwhich has a significant carbon content (around 3-5%) and consequently a low enough melting point (around 1200C) to be cast.

Through this process,ferrous oxidealso oxidizes to ferric oxide. The blast furnace reduces iron from the iron oxide, but the complete reduction reaction requires the addition of coke and limestone to the roasted ore. After the completion of different processes in the blast furnace, molten iron flows from the bottom of the blast furnace.
