Conclusion
Crucible steels remained the world's best, although very expensive, for some time. The introduction of the Bessemer process and other steelmaking processes gradually replaced it, being able to produce steel of similar (or better) quality on a much larger scale more quickly and cheaply. The Bessemer process and more modern methods differ from crucible steel production in that they remove carbon from the pig iron, but stop before all the carbon is removed, whereas the ultimate raw material for traditional crucible steel was wrought iron, to which carbon had been added by cementation.

Famous quotes containing the word conclusion:
“I have come to the conclusion that the closer people are to what may be called the front lines of government ... the easier it is to see the immediate underbrush, the individual tree trunks of the moment, and to forget the nobility the usefulness and the wide extent of the forest itself.... They forget that politics after all is only an instrument through which to achieve Government.”
—Franklin D. Roosevelt (1882–1945)
“I have come to the conclusion that the major part of the work of a President is to increase the gate receipts of expositions and fairs and by tourists into town.”
—William Howard Taft (1857–1930)
“No one can write a best seller by trying to. He must write with complete sincerity; the clichés that make you laugh, the hackneyed characters, the well-worn situations, the commonplace story that excites your derision, seem neither hackneyed, well worn nor commonplace to him.... The conclusion is obvious: you cannot write anything that will convince unless you are yourself convinced. The best seller sells because he writes with his heart’s blood.”
—W. Somerset Maugham (1874–1966)
