Not all aluminum is anodized. That's an expensive process and Al foil is NOT treated like that!!!
Tea-light candle tins as far as I am aware are also aluminum and should be avoided.
stinkyattic Reviewed by stinkyattic on . FOIL! i'm quite concerned that people are being advised to use foil when making bongs and pipes. DON'T! it is a major contributor in giving you altzhiehmers and it makes white spots on your lungs :eek: . try using the metal casing from those small 'tea light' candles instead. it's more solid, and doesn't give off carcenogenic fumes.
