· In India, ironworkers developed that combined the perfect ratio of iron to carbon. Using crucibles, or clay containers, the ironworkers would blend iron and charcoal pieces together in a high-temperature furnace. While cooking, the iron would melt and absorb carbon atoms from the charcoal.

Malleable iron starts as a white iron casting that is then heat treated for a day or two at about 950 °C 1,740 °F and then cooled over a day or two. As a result, the carbon in iron carbide transforms into graphite and ferrite plus carbon austenite.

Wrought is manufactured from forge pig by the following processes.. Refining, or exposure when fused to a strong current of air which removes part of the carbon. Puddling, by which the molten metal is still further exposed to a blast of air and oxidising substances in a reverberatory furnace. The remainder of the carbon is thus removed, and clotty lumps or "puddle halls " of pure appear.
