By this method he hoped to cause the new process to gain in standing and market share. Bessemer claimed that it “was the spark which kindled one of the greatest revolutions that the present century had to record, for during my solitary ride in a cab that night from Vincennes to Paris, I made up my mind to try what I could to improve the quality of iron in the manufacture of guns. Bessemer’s company became one of the largest in the world and changed the face of steel making.
He writes, “They have, among others, particular invention for the melting of iron, without the using of fire, casting it into a tun done about on the inside without about half a foot of earth, where they keep it with continual blowing, take it out by ladles full, to give it what form they please.

It was replaced by processes such as the basic oxygen Linz—Donawitz processwhich offered better control of final chemistry.
