Carburization is a heat treatment process, in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. Unlike modern steel making, the process increased the amount of carbon in the iron.

The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

This causes the iron in the ore to fuse chemically with the carbon from the charcoal. The more carbon dissolved in the iron, the lower its melting point. The amount of ore to fuel, and the supply of combustion air determine whether cast iron, steel, wrought iron, or a useless lump of metal will form (Alpern 82).

Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
