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:

    Books of natural history aim commonly to be hasty schedules, or inventories of God’s property, by some clerk. They do not in the least teach the divine view of nature, but the popular view, or rather the popular method of studying nature, and make haste to conduct the persevering pupil only into that dilemma where the professors always dwell.
    Henry David Thoreau (1817–1862)

    We aspire to be something more than stupid and timid chattels, pretending to read history and our Bibles, but desecrating every house and every day we breathe in.
    Henry David Thoreau (1817–1862)

    I am not a literary man.... I am a man of science, and I am interested in that branch of Anthropology which deals with the history of human speech.
    —J.A.H. (James Augustus Henry)
