Make sure that there is no clear finish on flask and degrease it with mineral spirits. Place in large plastic bag and put in a piece of cloth, rag paper towel with household ammonia on it.  Seal bag and leave it for a few hours to a couple days.  Also, Birchwood Casey's Cold Bluing will do the trick.

 A light coat of salt, and vinegar, will give a copper flask a nice green color, that darkens nicely if you oil it. This mixture will damage brass though.

Spritz the heated piece with a solution of ferric nitrate....this gives a very believable dark brown color. I do fireplace tools this way.

Historic Houseparts make a brass darkening solution that works well for both brass and steel.

If you got any sulfur around it will put a nice aged patina on copper and brass. Guess what is one of the components in black powder? Wet it and rub it on and let sit.  It won't work as good as pure sulfur though.

Hard boil 2 eggs.  Crumble the warm yokes in a ziplock with the flask and close it.  In the morning it will have a nice color and it costs about a quarter.

After removing any clear finish, wipe it down with used cleaning patches.

I use Sulfurated Potash from Science Company that J.B. recommended. Works great. If additional coats are required for a darker finish, the additional coats won't wipe of the first like some patina formulas. Jerry
