It's difficult to 'blue' but you can turn it a shiny deep black by using Birchwood-Casey Brass Black.

A large sports shop might have it or they can probably order it in. A small bottle (about 3 oz) will last forever. Easy to apply.........but I can't speak to how well it will last.

This IS one method that the pros use. I did a bell this way for my brother enlaw .Worked exellent as a fast ageing process. Works on copper brass bronze.
An old traditional method of colouring new brass or bronze was to immerse the item in warm urine, producing a fine aged appearance in ½ to 1 hour. The reaction can be controlled to some extent by the temperature of the urine. Horse urine was commonly used, as their hay and oats diet produced a much greater ammonia content. After immersion wash in clean water and finish as previously described. This is one of the best methods of producing a realistic patination of age on these metals, simple, controllable and effective.

Didn't have a horse handy so had to do it myself.

I was experimenting with this sort of thing a while back, using a combination of heat, acids, salts and a galvanized steel bucket I accidentally created a wicked jet black finish on copper that is extremely durable. I was using the bucket to catch drippings from my patination experments and left it over night with a piece of pipe standing in it. The next morning some combination of acid, salt and galvantic action left this wicked finish on the pipe. Unfortunately I had no clue what happened in that pail overnight and despite a couple weeks of further trying could never reproduce the effect. I found that copper in contact with zinc immersed in a vinegar and salt solution produced a black coating but I couldn't make it durable, it would just wipe right off. Some contaminant in the bucket must have made this black coating durable, but I don't know what.
