Is it really that bad? I haven't seen much on the negative side in heating a good grade of wire before using.
metal oxides are very dangerous op. This has to stop, really. Noone is talking about it except me because people like to invent and try things all the time. They realise later what they did but its always too late.
Keep your metals clean, dont burn them, dont oxidise them, dont change their properties and dont inhale the fumes they produce.
To say it better, dont burn your pans on your house (if you do that, throw them away immediately and dont cook on them any more).
Also, not only you never burn the inside of your tubes on an atomizer but you clean it often. So you clean the remaining liquid (inferior issue) but you vape metal oxidation?
