i was trying to get at the point that aluminum would not be able to vaporize at such a low temperature. So it would stay solid, if it gets sucked through the bowl before you dump out the ash, it would probably get stuck in the resin before it entered your mouth. Even if it entered your lungs, these visible flakes are probably big enough that your cilia will eventually brush them out.
that's my logic at least.
