Pig Iron - History

History

The Chinese were making pig iron by the later Zhou Dynasty (1122–256 BC). In Europe, the process was not invented until the Late Middle Ages (1350–1500). Actually the phase transition of the iron into liquid phase in the furnace was an avoided phenomenon, as decarburizing the pig iron into steel was an extremely tedious process with medieval technology.

Famous quotes containing the word history:

    ... that there is no other way,
    That the history of creation proceeds according to
    Stringent laws, and that things
    Do get done in this way, but never the things
    We set out to accomplish and wanted so desperately
    To see come into being.
    John Ashbery (b. 1927)

    The history of every country begins in the heart of a man or a woman.
    Willa Cather (1876–1947)

    It’s not the sentiments of men which make history but their actions.
    Norman Mailer (b. 1923)
