yeah, i wouldn't worry about using foil on occasion. Just don't smoke every night with it and you will be fine. The toughest thing to get is a bowl if you don't have one. Really the only household alternative to aluminum that I know of is a bolt socket for wrenches (1/4"). They're those things that usually come in sets of all different sizes and you clip the square end to the wrench and use the hex side for the bolt.
