When I was doing research into vaporizers, may sites were saying don't buy one with an aluminum heating element, get a ceramic heating element instead. Now I read that the Silver Surfer Vaporizer has an "alumina ceramic" element. Does that mean other vaporizers had pure aluminum heating elements (a really dumb idea)? I am still concerned about the safety of vaporizers with aluminum ceramic: a) There might be some aluminum that hasn't formed a compound in the ceramic, and thus have some of the effect that hot aluminum could have. b) The high temperature of the element could undo the chemical bond in the compound. Even if these were both the case it would still be much better than a pure aluminum element, of course. I should add that other the vaporizer sites like the volcano don't go into as much detail about the heating element, and will just state that it is "ceramic," if anything at all. The SSV site claims that there are no toxins or metal ions given off by the element. Does anyone know if anyone has put a vaporizer's output through a mass spectrometer, or done similar testing?
