    Conservation of Cast & Wrought Iron

    In 1856 Henry Bessemer developed a method of blowing air through, rather than over, molten pig iron to oxidise away its carbon in a tilting converter. This reduced the conversion time to minutes from the hours required for Cort’s puddling process, and produced steel which was stronger than wrought iron.
