but i must be fair about the aluminum thing, the aluminum itself has to become very hot to begin to emit anything, i think well above the element temp in the volcano... but if i owned one, i probably would check into it... as soon as i found out my vapir one had a brush motor in it, i didnt want to use it anymore after checking into things like carbon in the lungs, but as far as the aluminum thing, i cant say that i have any proof of that either, and i figure that sinse u have a volcano, maybe u have motivation to prove incorrect the aluminum thing? ah? and hurry up will ya, im curious... VAPE ON DOOOOOOOOD!
