Pig iron : definition of Pig iron and synonyms of Pig

The Chinese were making pig iron by the later Zhou Dynasty (1122–256 BC). [2] In Europe, the process was not invented until the Late Middle Ages (1350–1500). [3] 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.
