    Quick question, i have a lot of copper wire, is there any good reason why copper wire cant be used to make coils?
    I've heard of somebody using it but i'm a bit nervous about trying it myself.

    Copper is an excellent conducter, which offers no resistance(?) therefore no heat.

    No heat, no clouds.

    I maybe wrong here.

    Search 'copper toxicity'.

    Also, when copper's heated it creates copper oxide. Search 'copper oxide toxicity'.

    Even if you want to test the waters of Alzheimer's or Wilson's disease or cirrhosis of the liver, it's far too conductive - you'd need two meters of 0.2mm wire for a 1ohm coil.

    Does that make it any worse than Nickel?

    It corrodes very quickly which creates copper oxide even without being heated and copper oxide is particularly toxic, so I'd say yes.

    Nickel's not the best in fairness but it's slow to corrode, the quantities measured in vapour are below safety limits, and if I was weighing up the lists of illnesses the inhalation of either metal might cause I'd side with nickel if I had to choose between them.

    I'm still not 100% convinced about nickel. I'd certainly like to see more tests before jumping in to the TC world.

    I've temperature control and i never use it(yet).
    The nickel is completely different from the kanthal

    Nickel can (under the right conditions) give off nickel carbonyl, which is a toxic and carcinogenic gas. My question is whether this can happen in vaping.

    I'd say the right conditions would be something like a long dry burn at 100w.
    Like that test they did in japan that caused the big vaping is bad for you song and dance last year.
