Rust bluing was developed between hot and cold bluing processes, and was originally used by gunsmiths in the 19th century to blue firearms prior to the development of hot bluing processes. The process was to coat the gun parts in an acid solution, let the parts rust uniformly, then immerse the parts in boiling water to convert the red oxide Fe 2 O

Hot bluing is extremely sensitive to certain impurities, and to properly cleaning the metal of all oil residue prior to attempting to blue it. If some specific impurities are present, or if all oil is not carefully removed, then the hot bluing always fails. If an adequate amount of water is not present, then the bluing fails, too.
The NaOH (caustic soda) and elevated temperature cause Fe 3 O 4 (black oxide) to form on the surface of the metal instead of Fe 2 O 3 (red oxide; rust). While it is physically denser than red oxide, the fresh black oxide is porous, so oil is then applied as post treatment to the heated part, which seals it by "sinking" into it.
