    Rust blacking is basically an oxidation reaction, nitric acid is a very good oxidising agent and a metal salt helps with the reaction and can deposit a small amount of ions on the metal surface to give a better finish. I used a nitric acid and copper sulphate mix for doing shotgun barrels some years ago and it worked nicely. Another chemical I tried that gave excellent results was a very dilute solution of silver nitrate, this is expensive but may still be easy to obtain since it used to be used to develop photographs.

    If you nip over to the Boinger bash this coming weekend you can look at a couple of examples I've fume blued.

    We're only 25 minutes further than Melbourne.

    Thanks anyway.
    No problem, Peter.

    If you're ever out this way just give me a shout though and I'll get the kettle on.



    All the best Mick
