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:
“So this
Is man; so—what better conclusion is there—
The day will not follow night, and the heart
Of man has a little dignity, but less patience
Than a wolf’s,”
—Allen Tate (1899–1979)
“of making many books there is no end; and much study is a weariness
of the flesh.
Let us hear the conclusion of the whole matter: Fear God, and keep
his commandments: for this is the whole duty of man.”
—Bible: Hebrew Ecclesiastes (l. XII, 13)
“The conclusion suggested by these arguments might be called the paradox of theorizing. It asserts that if the terms and the general principles of a scientific theory serve their purpose, i. e., if they establish the definite connections among observable phenomena, then they can be dispensed with since any chain of laws and interpretive statements establishing such a connection should then be replaceable by a law which directly links observational antecedents to observational consequents.”
—C.G. (Carl Gustav)
