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.
"...To be peaceful without being stupid, to be interested without being compulsive, to be happy without being hysterical, smoke grass..."
" A wondrous languor... possesses itself of your spirit, and spreads itself across your faculties as a fog spreads itself in a meadow... Hashish spreads itself all over life; as it were, the magic varnish. It colours it with solemn hues and lights up its profundity." - Charles Baudelaire, 'The Poem Of Hashish.
