    If you like the colors cool. The chemists (or alchemists) here will have to tell you what has happened. The blue/greenblue is a reaction with the copper. Make sure the horn is really clean and rinsed inside. I am not sure if what you did could be poisonous. Brass is a combination of copper and zinc.

    Here a bit more:

    Check out the part on "season cracking".

    The photos don't convey the colors exactly so it is hard to tell what was done where. What color is the bell flare? How did you create the nice straight boundary between the bell flare and the bell pipe? Did you just brush on the mixture that you created? How long did you leave it?

    This is a two-piece bell which looks to have been
    made by two different alloys. The boundary is the
    seam where the two parts are welded/solded together.

    Nice effect :cool:

    OH
    I really like it!! But you can already see the green coming in by the valves, I think in the 1st pic. Soon enough the whole horn will be green! Just try to keep it clean!

    how do you keep it clean without losing all the green?
    will it wash off or will it stay on?

    You will need tarnish remover. There are various products that are specifically made for brass tarnish (Tarn-X comes to mind). There are also generic metal polishes (Mothers Billett or Turtle Wax polishing compound) and then there are cleaning wax products. I think the cleaning wax is the best because it leaves a wax surface behind which helps to protect the metal and slow down the tarnishing rate. I picked up a can of Meguiars Cleaner Wax at an auto parts store but I imagine just about any good brand will work ok. But, whatever you do, do it frequently. It sounds like the rate of tarnish may be higher than normal now and you don't want your hands to start turning green.
