    That’s pretty awesome all the same!
    I definitely think the copper left remnants in the felt. If you use ferric chloride to etch Damascus with a copper wire submerged in the acid the Damascus comes out with an almost copper plated look.

      I did not know that. Interesting! :D

    That's science for you - always generating more questions than answers... 😅
    Nice crash course in etching different metals thought!

    I used to make my own project PCBs from circuits I traced out of hobby magazines... I have done some etching, but I never heard about "marking". But as you describe it, it's just re-deposition by electrolysis. So carbon probably does not deposits back on the damascus steel, but you could be turning some surface metals to oxides. With aluminium, that's exactly why it got brighter - most metal oxides are dark, but Al2O3 is white. Copper oxide is probably just plating copper back onto the etched surface, I think that's just the chemistry of copper electroplating.

    You definitely made more questions for your self. It will be fun to see what people say about this

      I'm genuinely looking forward to some explanations... whether they come or not though. 😅

    Very interesting video. Damascus etch was very clean and perfect.
    Interesting results👍👍🔥🔥🔥

    Try switching polarity for AL and maybe the CU. I know it works on AL, that's how i etch my 80% lowers (makes a really cool effect if it's been anodized, you just have to rough the anodization up a little).

    hi , can you please explain the diffrence between marking and etching and their both respective procedures?
    was confused looking at the video

      Skip to 5:10, should hopefully give you an idea. :)

    Cool stuff. Thanks.

    No nickel? Or did the pattern welded steel have it in the mix?

    • @PJTForging
      @PJTForging  3 роки тому

      Pure nickel is super expensive at the moment, but yes there is 15n20 steel in the pattern welded stuff which has a high nickel content.
      I'd have loved to have tried this with gold/silver/platinum too, but again, I am but a lowly poor youtubie. 😅

    i was so ready to laugh if you had stumbled upon a way to make brass look like copper after all the trouble mike had a couple projects back

      I mean... I may well have done! 😅
