An easy gun bluing formula can be made by mixing copper sulfate, sodium hydroxide, and distilled water in specific proportions. The metal parts are immersed in the solution to create a corrosion-resistant blue-black finish. It's important to follow safety precautions and proper ventilation when working with these chemicals.
Liquid bluing is typically available for purchase at grocery stores, drugstores, or online retailers. It is commonly used as a laundry whitener to improve the brightness of white fabrics during the washing process.
The chemical used for cold bluing is usually Selenium_dioxide.
Bluing agents used in laundry are synthetic compounds designed to counteract the yellow tint caused by some detergents on white fabrics. These agents are typically made in a laboratory using various chemicals and are not naturally occurring.
The approximate operating temperature for bluing with nitre- blue salt is around 290-310°C (550-590°F). At this temperature, the parts are immersed in a bath of the nitre-blue salt for a specific period to achieve the desired bluing effect.
There are several reasons bluing will not take on a gun. One is it stainless steel. Nope. Two is the bluing solution correct. If so, is the temperature correct, Brownells has bluing info for their solutions., follow these almost perfect. Also to be blued, it must be alloy steel. not pot metal, not cast, just steel. Don't get any brass, copper, zinc or lead in the bluing solution. lcjones
To make Mrs. Stewart's Bluing at home, you will need basic ingredients such as water, laundry bluing agent, and a container for mixing and storing the solution. However, it is recommended to purchase Mrs. Stewart's Bluing directly from the manufacturer to ensure the best results and avoid any potential safety hazards.
To grow selenium crystals with bluing charcoal and ammonia, start by dissolving selenium powder in boiling ammonia. Add bluing charcoal to the solution to act as a reducing agent and promote crystal formation. Allow the solution to cool slowly to encourage crystal growth, and then filter and dry the crystals for collection.
Birchwood Casey makes a chemical that removes bluing. In addition, Naval Jelly, a popular rust remover, will also remove gun bluing. (Bluing is a form of rust) Be certain that you are dealing with blued steel, and not anodized aluminum. A magnet will not stick to aluminum, but both the Birchwood Casey product and Naval Jelly will corrode aluminum alloy very quickly.
While guns are treated to "blue" steel, that is not the use of Baby Boy Bluing. It was a laundry product used many years ago. A few drops were added to the rinse water for white clothing. to improve their appearance. As laundry detergent improved, bluing disappeared,
Years ago there was a product called "Blue Away" I used it on my BSA and worked ok
Mrs. Stewart's Bluing was created in 1883.
We do a LOT of bluing, and the answer is going to be "it depends." If you are talking about hot-salt bluing like a professional shop uses then the answer is absolutely not. We do not plug bores in a hot-salt bluing tank because the pressure would cause the plugs to shoot out of the bore and splash 295 degree caustic salts everywhere. If you are talking about a traditional rust-blue where an application of bluing solution is swabbed onto the prepped steel, the part is allowed to oxidize (rust) in a humid cabinet, then boiled off in water and carded, the answer is yes. Bores do need to be plugged when rust-bluing simply to avoid any of the solution getting into the bore. We make plugs out of wooden dowel when we set up for this process - I know of no commercial reusable bore plugs for this purpose. Finally, if you are referring to swab-on "cold blues" - I would imagine you could plug bores similarly to the rust blue process. sales@countrygunsmith.net
Bluing, as it relates to firearms or metal in general, is a permanent surface treatment under ideal conditions. Poorly maintained bluing will fade or flake off. Bluing is a "form of rust", an oxide layer on the outside of the metal. You can remove it using various abrasives, but yes it is permanent.
Gun Bluing is a chemical that is brushed or rubbed on the metal of the gun. It acts like a die. It can be purchased at most gun stores. The metal has to be stripped and cleaned first then the bluing is applied in even layers to make it darker.
If not a refinish, 500 or so.
