    Important tip!! Don't do this in a workshop you care about - it releases caustic vapors and you will find anything made of steel or cast iron forming a red surface rust almost immediately. I do this outside now for that very reason, the first time I performed hot caustic bluing in my shop I found my lathe, drill press, and other tooling had a red rust on the bare metal surfaces the next day. It cleaned off fine but lesson learned. Also be careful on the acid step, if you want a bright polished finish you need to start with bright polished steel, but too long in the acid or too strong acid will take the polish back to a matte finish and the blued steel will be matte also.

      Yes indeed.
      It is an exceptionally dangerous process as caustic DOES NOT stop corroding the skin and flesh like acid.
      One drop on unprotected skin will eat through and make it bleed.
      I was a gunsmith.

      You're overreacting. We had a 10,000 gallon caustic tank at 970+F (melting pure caustic) and it was an open air tank. It's at most going to eat paint. As long as you have decent airflow though and not condensating the tankvapors you'll be fine.

      The first time I tried this, the parts came out perfect. Beautiful black and shiny. It was a knife made from leaf spring steel and other parts made from mild steel. My next attempt, same metal, same solution, same methods…one knife came out a gorgeous coppery color, two came out black. I have no idea what I did different. One poster here says you can get chemical skin burns just from the air. That’s a real thing…I could feel my exposed skin mildly stinging, and I had the garage door open.

    • @jaredrattray
      @jaredrattray 4 หลายเดือนก่อน +2

      @@6Sally5 The red coppery colour is most likely red iron oxide which means the temperature of the bath went too high. I have resolved this by taking the reddish parts and washing them of caustic salts and then boiling in a pot of distilled water. This converts the red iron oxide to black iron oxide. Once it turns black again you can return it to your bluing salts and it will take an even darker blue.

    hi, I'm from Russia. I really like your videos on restoration. It's really an interesting activity. I've learned a lot about how to do it thanks to you and your recipes that you share with us. I also want to share with you my recipe for hot oxidation without caustic based on ammonium nitrate 10-25 g /l, carbamide 5-10 g / l. and it works just as well as caustic, but at times safer. There are also more complex compositions of ammonium nitrate with chlorates, persulfates, and amines, and they all work well. you can find many different patents for these compounds.

    • @beyond.ballistics
      @beyond.ballistics  ปีที่แล้ว +3

      Take my words with a pinch of salt, since I'm not an environment expert, but Sodium Hydroxide is widely used as a drain opener. Actually most drain cleaners nowadays are mostly sodium hydroxide, so if you can use drain cleaner in your house, you should also be able to dispose of the caustic bluing solution in the drain, once it cooled down to room temperature. Potassium nitrate is a naturally occuring salt, and massively used as a fertilizer, so that shouldn't be an issue as well.
      Industrial amounts of said wastes would instead certainly have to follow specific disposal guidelines.

No steel mechanical property is affected at or below those temperatures. The rule of thumb is to start worrying about messing with the heat treatment when you go above 200°C.

      10% citric should remove the existing bluing in a few hours. If it doesn't, either the surface is still oily, some form of coating was applied to it, or the black you see is not bluing or some other coating.
      Try scrubbing with acetone and redoing the citric test, adding a bit of dish soap into the solution. If this doesn't work, it's definitely not a normal bluing.
      A quicker acting, but still safe to use acid is oxalic acid, 5%.

      This is a proper black oxide conversion coating, so it has the same wear resistance of regular bluing. Actually most black oxide finishes, including gun bluing, are made with this process.
      Cold bluing is instead chemically different (coating of copper selenide) and much less wear resistant.

      Coming in late, I can't see any reason to use a buffing wheel on a blued/black oxide surface. All polishing is supposed to be done before bluing. Only oil and a cotton cloth should be used after bluing and then not a polishing action; just to apply oil to prevent rust. I've been a teacher for community college gunsmithing classes and taught hot bluing as part of the curriculum.

    So, is the HcL just a degreaser? Or is it chemically critical to the process?

    • @Ju379an
      @Ju379an 3 หลายเดือนก่อน

      Its just a degreaser, paint thinner or acetone its enough for degrease the metal

    In your formulation could sodium nitrate(NaNO3) be substituted for potassium nitrate (KNO3)?

    • @beyond.ballistics
      @beyond.ballistics  ปีที่แล้ว

      Yes it can. Actually most commercial solutions use sodium nitrate instead of the potassium one.
      I only used potassium nitrate in the tutorial because it's usually more common. You may need to adjust the amounts slightly.

    I used to do this in a gun factory and mixing the solution and boiling it is very dangerous it can erupt like a volcano if you do it wrong, i cant remember the correct proceedure but you must find out before trying it.

    Do you need to wear masks with these techniques if so what level of protection? 👍

    • @beyond.ballistics
      @beyond.ballistics  ปีที่แล้ว +5

      The only time when there are airborns is when handling dry caustic soda. Once it's dissolved there is no breathing hazard. What you need to be protected from is the liquid accidentally ending on your body.
