According to Wikipedia (the know-it-all web source):

"Bluing is a passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish. True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (Fe3O4), the black oxide of iron. Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic action. A distinction can be made between traditional bluing and some other more modern black oxide coatings, although bluing is a subset of black oxide coatings."




We believe that you don't have to know how to crack hydrocarbons to put gas in your truck. Likewise, all you need to know here is that we have the equipment, knowledge, and skill to put a very nice blue/black finish on the steel of your firearm. It's a finish that will stand up to years of hard use and protect your firearm from the wet. And we can do it without Mr. Wizard and the chemistry lesson. Come in and let's talk about your needs.
