This causes the dissolved impurities (such as silicon) to be thoroughly oxidized. In these processes, pig iron is melted and a strong current of air is directed over it while it is being stirred or agitated. Traditionally pig iron would be worked into wrought iron in finery forges, and later puddling furnaces, more recently into steel. 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. In Europe, the process was not invented until the Late Middle Ages (1350-1500). For steel production, flux stones are used to make pig iron bars and smelt. The Chinese were making pig iron by the later Zhou Dynasty (1122–256 BC). Dwarf Fortress (officially called Slaves to Armok: God of Blood Chapter II. As pig iron is intended for remelting, the uneven size of the ingots and inclusion of small amounts of sand was insignificant compared to the ease of casting and of handling. When the metal had cooled and hardened, the smaller ingots (the pigs) were simply broken from the much thinner runner (the sow), hence the name pig iron. Such a configuration is similar in appearance to a litter of piglets suckling on a sow. The traditional shape of the molds used for these ingots was a branching structure formed in sand, with many individual ingots at right angles to a central channel or runner. The recipe for pig iron is: one iron bar, one flux material and one fuel create one pig iron bar. Pig iron has a very high carbon content, typically 3.5–4.5%, which makes it very brittle and not useful directly as a material except for limited applications. Pig iron bars can be created at a smelter by a dwarf with the furnace operating labor activated. Charcoal and anthracite have also been used as fuel. Wiki says: Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux.
