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:
“History ... is, indeed, little more than the register of the crimes, follies, and misfortunes of mankind.
But what experience and history teach is thisthat peoples and governments have never learned anything from history, or acted on principles deduced from it.”
—Georg Wilhelm Friedrich Hegel (17701831)
“Perhaps universal history is the history of the diverse intonation of some metaphors.”
—Jorge Luis Borges (18991986)
“The custard is setting; meanwhile
I not only have my own history to worry about
But am forced to fret over insufficient details related to large
Unfinished concepts that can never bring themselves to the point
Of being, with or without my help, if any were forthcoming.”
—John Ashbery (b. 1927)
