Aluminum boiling temp is far above cannabinoids temp and it would not Distill over during processing
That’s a reasonable hypothesis, but you should have it tested. When aluminum is complexed as part of a molecule, it can easily boil at lower temperatures. For example, Aluminum Isopropoxide is easily purified via distillation.
Also, since wiped film has zero fractionating plates, lots of stuff can boil over unexpectedly. Vape carts are also concerning, I’m not sure if anyone has done really solid work measuring metal residues in vapors yet.
