I have a friend who engraves scenes, names, etc on aluminum commemorative hard hats and was asking me about solutions to patina aluminum much like liver of sulfur does to silver. I had no idea, so thought I would ask here Check out some of his work here silverhighlights.com/

Aluminum is usually anodized for color. I'm not aware that it can take a patina in the traditional sense. I worked in the letter department of an aluminum sign making company once upon a time, welded quite a lot of aluminum and made lots of walgreens signs. Aluminum never went dark. the stuff was always powder coated or painted.

I am thinking that aluminum is porous so wood stain might work. I am guessing here. Jim

The aluminum panel at the bottom of our side screen door gets visited/sprayed by cats from time to time, definitely has left a patina...

Thanks for the replies. I had told him I was only aware of anodizing, but would ask around

Yeah, you wouldn't patina it. Here's some info on the anodizing process - link.
And on their (finishing.com) forum, someone also asked about coloring aluminum for jewelry - link 2. Specifically, look at the third answer.
But always remember - Anodizing is dangerous, because of the introduction of acid and electricity. Unless you know what you are doing, and take precautions, DO NOT TRY THIS AT HOME.
