Confessions of ignorance: Pig iron
02/02/2012 · Pig iron is the result of an intermediary process in the smelting of iron. I don't know that I want to dig into the whole iron smelting process just now, but basically when you first smelt iron ore, you are left with pig iron, which, before further refining, has a lot of carbon in it. This makes it brittle and largely unusable.
