Mill scale is a mixture of iron oxides and other impurities formed in high temperatures. Rust is also a mixture of iron oxides but is created in the presence of moisture in everyday temperatures. For the same thickness, rust is far easier to remove than fresh scale. If scale is old, dry, and rusty, it is almost as easy to remove.

The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely superseded bloomeries.
