Nitre bluing a few gun parts

[satan31337]

i have totally had a tub uf salts ex plode on me from a hot air bubble

[jeremystube100]

Thanks for the Tips

[wootwoot409]

sire i want my hole barrel of that blue peacock color how will i go about that

[backyardsounds]

I have seen home made formulas that are mostly composed of Potassium Nitrate (KN03) or sodium nitrate (NaN03). If you drop some carbon of any sort (even sugar) while the solution is molten, it could erupt into a non extinguishable fire. You can see this effect in a small test tube with molten KNO3 and dropping in a gummy bear....quite the light show.

[mrnitro30103]

great job! what about bluing a barrel with the salts? is it possible without compromising the inside part? should it be sealed? thanks!

[wasanoix]

hello im new on this , but would like to try , where can i get the salts? thanks in advance!!!!!

[sclogse1]

Try a black sharpy.

[sclogse1]

I tell you what works super fast. A black wide tip sharpy pen. Let it dry, touch up a couple of times, buff down. Looks pretty damn good. really. I just did it on my Tagheur replica monaco watch that should have come in a graphite black metal finish...but come super shiny like chrome. (It's a steel case). It's my error, as the ad lighting gave the metal a gray black look. Anyway, I stayed off the back, but even did the knobs. Dries in five minutes. You can choose the type of buff to give it.

Will doing this affect the toughness of the steel parts?

[DavidRWymore]

Will stump remover work? I've read it will. It's potassium nitrate

[ArtistBlade1972]

What is the difference between this and normal heat coloring in say an oven?

[voltagedrop]

Thank you for this video. Will you be doing one on rust-bluing?

[serioede]

Hi coltgravel,

Great video !!!!

where can I find nitrate blueing saltzs ? Who sells thems?

Thanks,

Hello dear i want to color my damascus steel knife what should i do

I want blowing blue color

Viki

[CrashQuick7]

Looking forward to your rust bluing video. Thank you for this one!

[therealbeaker]

thank you for posting such an informative post - total contrast to the majority of youtube drivel.

[SuperFuely]

Hello, Great video. Question, my parts are factory blued now, would I need to polish off the factory blue in order to nitre blue them? Thanks

[tedcrum]

Thanks for the excellent video! I would certainly adopt your safety measure of keeping the quench tank distant to avoid spattering. Is the nitre also hot enough, being a strong oxidizer, to cause rapid burning of small combustibles that might fall in, or does the commercial admixture reduce the melting point enough to eliminate that hazard?

[dozzy000]

i've seen another recipe that uses water, caustic soda, and potassium nitrate..................will that work too?

[coltgraver]

That recipe is for hot caustic bluing which produces a black color. It is what most factories use on guns. It has it's own safety hazards as well.

[dozzy000]

hi!,thanks for the tip,can i sumerge my revolver in this recipe, but i mean, my whole revolver? only with the cylinder out the rest of the revolver wouldnt be disassembled, cant that be done?

[coltgraver]

I wouldn't reccomend it. First, the gun would need to be polished before going into the salts. It would be impossible to clean it without disassembling it. Second, the process offers very little protection against wear and corrossion. It is only decorative. Third, I wouldn't do a whole gun in nitre blue, only small parts to be used as accents.

[dozzy000]

thanks for the tip man!u are helping me a lot!really,i will try to disassemble the whole thing,but i just dont have the tools,but a saw a link that had a recipe on how to clean it....it said that if it was very dirty and rusted it could be sumerged in caustic soda and water and boiled for a little while and that would take away all the rust and grease and would clean the gun,so i was planning on doing that?would u recommend it?the caustic soda would "eat away"all the little springs?

[JJLN1988]

@dozzy000....no men, is a totallly lie, i used that method and doesn't work.

[gunsmithjones]

A much better setup than CST.

[tallsaultube]

Hi, fantastic clip.

I want to try this technique for clock hands bluing. I bought some Potassium Nitrate (KNO3) and I wasn't sure if that's the salt you are using.

The other issue is how would the temperature effect the color?

Thanks, Saul.

[april231953]

I want to try this on some blued (oxynate, I think) screws. I can easily polish the face of the screws, but what effect will it have on the parts still blued? Must I bead blast the blueing off?

[coltgraver]

It won't affect the existing bluing.

[1stMarineCapt]

@coltgraver Will this sort of bluing process affect on steel's toughness? I know this type of protection wouldn't last long, but between cold and hot bluing, which one last longer?

[huaste07]

NICE , SUPER  VIDEO, TANK YOU!!!

[kowades]

thank you so much for this video :D

cheers

[DannyK426]

What brand salts are you using? And do you have any experience using Potassium Nitrate for nitre bluing? Thanks for the video!

[april231953]

@DannyK426

Danny, did you ever get an answer about Potassium Nitrate?

Do you yourself have any experiece with it?

Rgds,

Mike

[DannyK426]

I ran into the poster of this video on a message board (cant remember where now), but he mentioned using the nitre bluing salts available from brownells. I have no experience with them any type of bluing. I have read that the commercially available nitre bluing salts are mostly KNO3 (potassium nitrate), but include some other salts to lower the melting point to a more manageable temp.

[coltgraver]

Sorry for taking so long to respond.

I'm using Brownell's salts which have the added ingredients to lower the melting point. I haven't used straight Potassium Nitrate.

[dozzy000]

hi man!, can i sumerge my whole revolver in that liquid? i mean my whole revolver without the cylinder and the wood handle of course...........can i do that?

[JasRobe]

Great video! How well would this hold up on a knife blade (damascus steel, 1095+15N20)

[coltgraver]

It will wear off quickly if the knife is used but it could look pretty good.

[ArtistBlade1972]

@JasRobe It will ruin the temper of your knife...

[schecteromen666]

Your videos are great! Well done.

[calebib]

Nice video David. I've had good luck using a Lee electric lead melter for heating nitre salts for bluing small parts. It heats quickly and holds temp really well. I watched Pete Mazur's video on nitre bluing and got a lot of great tips from it. By the way, I'm back in Denver now and working with Bart again.

[coltgraver]

I'll be stopping by at some point. Shoot me an email.

[kdiver58]

What salts would you recommend using? I saw a Larry Potterfield video of this and he used a pinkish colored salts.

[calebib]

Nitre bluing salts come pink and when they are heated for the first time the pink turns into a foam on the surface that must be skimmed off. The salts that Larry used were Brownell's salts.

[LLCranford3]

Coltgraver, Great Video! I am a new gunsmith, would you recomend nitre bluing for refinishing the frame and action of a circa 1925 Luger Pistol? Could a whole luger be blued this way?

Thanks!

[Southern661]

does this treat the metal to prevent rusting? will this scratch off?

[coltgraver]

No, it's only decorative. It will wear off much quicker than regular bluing. It's normally used on parts that don't get handled that much. Screws, pins, etc.

[shadowblack1987]

And yet you did the trigger and safety? O.o

[coltgraver]

Yes I did. The pistol is getting full coverage engraving and I doubt that it will see much use. I wouldn't nitre the safety on "my" carry gun but I'll happily do it on someone elses gun as long as they are paying for it.

[shadowblack1987]

haha :P

[blueyddevil5]

Is there anyway to blue stainless steel?

[coltgraver]

There is a chemical that will blacken stainless that is used like regular hot bluing salts. A gunsmith that I work with uses it on his custom rifles.

[GrandeEscuadra45]

thanks coltgraver for the comments i will just hardchrome my handgun much cheaper then brownells thanks

[GrandeEscuadra45]

hey coltgraver what brand and chemicals would you recommend for hardchrome or stainless steel or nickle plating and is it the same as nitre bluing where can i find it thanks

[coltgraver]

There is no way to apply stainless steel to a gun, it has to be made of stainless. Hard chrome will need to be done by a plating shop. Brownell's and Midway both sell kits for e-nickel but you could have it done by a pro for about the same price. It is not the same as nitre bluing. Brownell's has complete instructions that you can download.

[Grande1911]

nice video i have a question  instead of cold blue my handgun can i stainless steel or hard chrome my handgun hope to here from you guys thanks

[coltgraver]

You could hard chrome or e-nickel it and have a look similar to stainless steel.

[rnmc]

Nice video, I enjoyed it. Just a question, how does this type of bluing hold up against the cold blue products?

[coltgraver]

It holds up a bit better but is really only a decorative finish. Rather than forming an oxide on the surface of the part, like hot or rust bluing, the heat just colors the metal without leaving any protective coating.

[rnmc]

ok, Thanks!

[lukaaxali]

i cant understend what kined of salt is it? i need to fix my gun. can you tell me pls

[coltgraver]

It's "Nitre Bluing Salts" from Brownell's. It's a mixture of potassium nitrate and a couple other compounds.

Send me an email or private message describing what you need done and I'll see if I can help.

[Kyocera234]

great video, I reall have no idea why I watched it, guess it's a "guy" thing. I like the engraving too.

[1desertsunrise]

Excellent video. I think that I'll try nitre blueing since you showed how easy it is.

[5OclockCharlie]

Beautiful work ! And the video was excellent, better than AGI's :)

[coltgraver]

Thanks guys, glad you like it.

[8MADJACK]

Excellent vid, thanks for sharing.

[machinedcreations]

Great show! Thanks for sharing.
