"Some pieces of pig iron on one side of the bath attracted my attention by remaining unmelted in the great heat of the furnace,

and I turned on a little more air through the fire-bridge with the intention of increasing the combustion...Thus a new direction was given to my thoughts, and after due deliberation I became convinced that if air could be brought into contact with a sufficiently extensive surface of molten crude iron, it would rapidly convert it into malleable iron."
