We are making a copper vent hood for our cooktop. We want to use the baking soda method to age it to a brown color. Is this safe to use over a cook top? Do we need to put some kind of finish after aging it?

Baking soda is food safe. The patina from the baking soda should act as a finish and protect it from oxidization.
