Smoke aluminium?

[iknewmroctopus]

Does anyone know if the foil used to cover a hookah bowl burn off and
go into the smoke? I heard that aluminium in the system causes
alzheimer's. I've thought about it before but never too deeply. Any
thoughts?

it kno it can happen, but doesnt happen often, ive experienced 2 kinds
of harsh smoke, 1 when the tobacoc burns, it just tastes bad and is
slvagable by blowing the valve, but when the burning get hot enough to
melt the foil you know the flavor is awful and you should just stop
there, ive only had it happen 2 or 3 times in my 4 years but i kno it
is possible for the foil to melt

Tin foil, from what I understand,  will burn-off and go into the
system.  Don't use metal screens for smoking because they
SUCK!!! 

You should be safe with aluminum foil,  but make sure you get the
thin foil,  not the heavy-duty stuff.  Everybody uses
aluminum foil.  If I were you,  I'd order a bunch of Hookah
foil packs from a company like Hookah-Shisha.com,  because they're
convenient and thin.  I'm using store bought aluminum foil, 
and it's a pain in the neck to always have to cut-off pieces for my
smoke.  The reason being because I smoke several bowls a day and I
find myself constantly cutting pieces of foil.

hookah foils have no additives like store bought aluminium foil and are the safest alternative.

Stainless steel screens are OK, but your bowl won't last as long.
With a new steel screen, braize it with a blow torch to burn off any surface impurities.
I have an attachment for small propane cannisters.

Someone on a forum earlier this year works in a shop and can make
stainless steel screens. I want to sell them now but can't find
him......

Hookah foils are THINNER than household foil as well, so less
carcinogens are burned off from THAT foil, simply because there's less
present!
Only use foils made for hookahs if you're gonna use foil at all!
