    Top notch stuff!

    Hope the info I sent you helped... I have more on brass finishing coming as well. I also have some really interesting solder tricks...

    Yes it did. It caused me to dig out a book that I bought awhile back called The Colouring, Bronzing and Patination of Metals. I found a recipe I want to experiment with but not sure where to source the chemicals. eBay? I need copper nitrate and acetic acid. I've got a block of sal ammoniac on the way. Everything else I can source or sub locally. I can sub vinegar for the acetic acid but the recipe calls for 6% solution concentration but vinegar is 5%.

    Def interested in your solder tricks

    Depending on how much you need, here's a source for the copper nitrate:

    (Awesome site. Take a while to look around while you're there.)

    They don't carry acetic acid, but you could always improve the concentration in the vinegar through distillation. The only hard part would be making sure you have exactly a 6% concentration.

    Thanks for the link! Looks like what I need. After reading some more, looks like they make vinegar in 6% concentrations. I'll chase one of those brands.

    Makes me wonder, would hydrometer readings be able to get you to the 6% after distilling it? You'd have to cut it with distilled water to essentially weaken the ABV.

    Now I've got something to research.

    Edit: I see you're looking to source out 6% vinegar of the shelf. Regardless, you've piqued my interest.

    I ordered some 10% vinegar that's used as weed killer. DT keep me posted on your research. Its been way too long since my chemistry courses. I'd be curious to know what you find.

    What patina are you using? I might have a simpler alternative.

    BTW, posting my black patina results soon.

    From page 295 of The Colouring, Bronzing and Patination of Metals
    Blue-green patina on pink ground (semi-matt) produces variegated coloring with some yellow / yellow green coloration

    Copper nitrate
    Water
    Ammonia
    Acetic Acid
    Ammonium Chloride

    Repeat application for 5 days

    Sea salt, tap water and methylene chloride.

    That may not give the exact color you want, though. BTW, methylene chloride hurts like an *Elder Swear* if you get it on your bare skin, and plain water won't get it off. Soap and water will, though.

    If I can get the satellite to cooperate, I'll post more pics and formulas.
