Can you’re blue a gun barrel?
Bluing is a thin protective shell of black iron oxide that protects gunmetal from rusting. If most of the shell has worn away, you’ll want to get it reblued by a professional, since the process is fairly complex. However, if it just needs a touch-up, you can reblue your gun at home.
What is hot bluing?
The bluing process involves treating a gun with a solution that turns red iron oxide or rust (Fe2O3) into black iron oxide (Fe3O4). Bluing also creates a thin protective layer that protects guns from damaging pollutants. The process turns a gun barrel blue because black iron oxide has a blue-black color.
What does bluing liquid do to metal?
Bluing is a process used to improve the condition and aesthetic qualities of damaged metal surfaces on a wide range of hobbyist equipment. Bluing earns its name from the resultant blue/black finish which forms following the chemical reaction after applying the gel to a steel surface.
Which is better hot or cold bluing?
The cold blue is more of a coating on the steel using chemicals that color the metal. Hot bluing uses harsh caustic salts at closely regulated temperatures and ph levels to actually get into the metal. The mineral content of the water used can also affect the color and quality of the bluing job.
What is the difference between Perma Blue and Super Blue?
The “Super Blue” has more of the selenium. Which is why on their website, Birchwood Casey advertises the Super Blue as, “For blueing highly polished steel parts and hardened steels containing nickel and chrome alloys” where the Perma-blue seems to be promoted more for “touch up” and regular firearm bluing.
What is browning a barrel?
The barrel is left exposed in the air for about 24 hours, after which a thin layer of reddish brown rust is formed on the surface. After this, the barrel is “carded” by rubbing it with a hard brush or steel wool, which removes the acid from the surface.
Should you Reblue a gun?
The short answer is no. If it’s your intent to maintain a firearm’s collectibility and value, the answer is usually “no”; don’t re-blue your gun. Firearms with an original finish, even if they have visible wear and discoloration are generally more valuable than those that have been refinished (re-blued or parkerized).
Does Naval Jelly remove gun bluing?

Does refinishing a gun affect its value?
The stock and fore end wood would be refinished, again, using the original Winchester methods. This is a costly process, at least $2000.00; however, it could increase the gun’s value to about $12,000.00. A worthwhile return on investment. There are times when even cleaning a gun can destroy its value.

Does hot bluing prevent rust?
Hot bluing does not stop rust. I have found that if you do the process right it makes for a great finish and look.
Is Parkerized better than blued?
A quick Google search seems to confirm parkerizing is a superior protectant vs bluing. Like others have suggested though, I wouldn’t go with either if I had the option. There are much better, more durable, and not very expensive modern finishes that both offers much better corrosion AND wear protection.
Does bluing harden steel?
Bluing or tempering a steel screw is usually the last part of the heat treatment procedure; remember the same process and technique can be applied to any other steel component. The first step is hardening the surface of the screw, with the temperature depending on the composition of the steel.
Can you blue galvanized steel?
This is why: I’m bluing some galvanized steel washers to use as accents on a leather coat. I wanted to age the metal and darken it, and bluing is definitely the way to do this. I’ve done a few test pieces, and they’ve turned out wonderfully.
How can you change the color of metal?

How do you blacken steel with heat?
Steel is heated to 400°F, then covered in a mixture of beeswax and linseed oil, then the metal is reheated to set. This process is sometimes done with oil only.
How durable is cold blue?
Cold bluing is not particularly resistant to holster wear, nor does it provide a large degree of rust resistance. However, rust bluing small areas often match, blend, and wear better than any cold bluing process.

Is bluing rust resistant?
This isn’t the only method to obtain the oxide layer, it’s but one of many. Some sources have stated that bluing provides rust resistance while others are skeptical since most oxide layers as a result of the process are merely 2.5 micrometres (0.0001 inches) in thickness.
What is parkerizing a gun?
Parkerizing is the process of protecting ferrous metals from corrosion and wear by applying a chemical phosphate coating. Parkerizing is an excellent gun coating in its own right and it also makes a perfect base for our DuraCoat® Firearm Finish!
