Speeding the aging of copper

Is there a simple way to speed the aging oxidation of copper? I am using it for picture frames and want the patina on it asap.

Two possibilities: 1. Go to the book section and buy the book on patinas. 2. bake them in the oven at increasing temperatures and time until you find the one that gives you the oxidation level that you are looking for. I would experiment on scraps.
