they do not. Even hair dryer coils don't generally glow, and the old vapes used the same wires, at sub-1% of the wattage. 5-8W instead of 800-1500W. That wire was called "Kanthal", and for a while vapes went to nichrome and titanium and various other things. I am unsure what the "gold standard" is now, but i doubt it's still kanthal unless it's a cheap chinese vape "bar".

anyhow, as other people and myself said already, the metal never gets hot enough to incandesce, not even remotely close!
