Do you mean you use a bowl as tinfoil? I dont think is good if your burning the tinfoil.

To have an awsome bowl, and ive asked this question many times before i found one, juts get a socket head wrench. Pop a screen down in it and theres your bowl.

You can attache different sizes to different thing. I use one for my gravity bong. One for this pipe i made. And one fore my bong. If you find some plastic or metal tubing around the house or hardware store you'll be set.

I hope this helped, if you didnt understand just tell me and ill try to explain it better.
