One of the most common arguments I see on ECR used against users who advocate or inquire about coil temperatures produced at high wattages is,
"well, when your wicks and coils are wet you don't see them glow red like it does when you dry burn therefore its cooler,"
there may be several physical properties the coil has at high temps that are being overlooked.

- Just because it doesn't glow red hot doesn't mean its at a lower temperature. Coils that are glowing red hot are producing radiation with wavelengths that fall within our visible spectrum. A red hot coil is producing wavelengths at about 600nm (yellow end of the spectra). This same red hot coil may also be producing wavelengths at a higher frequency, say for example 830nm, which I found Kanthal to produce with a 2 ohm coil @9.5 watts. 830 nm falls within the IR radiation spectrum. We can't see IR radiation but take my word for it, @ 830nm that coil was damn hot. I used Spectroscopy in an unconventional manner today with some surprising results.
- Have you ever made a micro-coil and noticed the two ends of the coil are red but the center is still grey/dark? Next time this happens pay close attention; not only is this coil shorting but the center of the coil is hotter-n-hades yet we don't see it glow. This is because the center is radiating heat at a wavelength who's frequency it too high for us to see and thats falls in the Infra Red spectra, similarly the ends are cool enough to emit a wavelength long enough for us to see. Remember, our coils heat up from the center outwards.
- I am just beginning to explore and understand the real physics behind thermodynamics, heating elements and radiation. What I am saying is by no means final or gospel. I am no more than a curious scientific brain who loves vaping as a hobby, has access to some great instrumental/analytical machines and wants to keep "we the people" as informed as possible. I'm not funded by anyone or any entity. All of the money that goes into my research comes directly from my own pocket. I have kept it this way to keep from having to bend to the will of those with hidden agendas.
- If you have questions feel free to ask; I will answer them the best I know how. If I can't I will find someone who will.
- PHYSICS EXPERTS CHIME IN I would love your input. Feel free to rip my hypothesis apart.
