What is the difference between Salt Bluing and Rust Bluing?
The difference is extensive. Salt bluing is a conventional emersion bluing method in which bluing salts are used in a high temperature liquid solution to produce the blued finish. Rust bluing is a much more time intensive, low temperature process in which the bluing is “applied” to the metal. Rust or Belgian bluing as some refer to it, is only required on double guns that feature soft soldered barrels such as the Browning Superposed, the Winchester 101, 21 & 23, L.C. Smith, Perazzi, Krieghoff, and Beretta. Our bluing products are used exclusively by Midwest Gun Works and are not for sale to the general public.
