Oh dear. When this thread first started, I thought I had some rudimentary knowledge about TC. Somewhere, halfway through the thread, I thought I was beginning to understand the technology better. Now I'm totally lost...
But thank you all for your contributions. This is a great thread, no matter where it leads us.
Am I ready for TC? I guess I'm still on the fence.
I just think 100 or so degrees is kind of low but couldn't say for sure. Either way 100 or so or 200 or so, way below the 400 or so in the tests. I do believe over 400 is obtainable but not in the set ups we were talking about

Those temperature will result in chard cotton so you might as well roll it up and smoke it. Sure in the tests they might me achieving those temperatures to make the study prove what they want.
Again what I did shows the external temperature of the coil where the vapor is actually coming from that I am inhaling.
I dont know if this is helpful or makes it more confusing.
VG and PG vs Temperature
Just to show that water inside eliquids is very important for the behaviour in temperature. So, eliquid with different water percentage has different evaporation temperature.
So, my opinion is that eliquids with different water percentage has different evaporation temperature.
When we compare VG eliquid with PG eliquid for the behaviour in temperature they get evaporated, we have to take note for the water concentration inside. All the VG or PG eliquids do not have the same concentration of water and/or flavour inside. If a PG eliquid does not have water at all (only flavour e.g.5% inside) then it is very different to another eliquid of VG having 10-15% water and 5% flavour dissolved.
If you take a close look in boiling points' differentation you will see that 5% difference in concentration give even 30 degrees difference in boiling point (VG 90% or 95% concentrated).
Just to be more accurate and realistic.
I would think that it would be Helpful and Useful.
Because if the Vaporization point of an e-Liquid can be Lowered by adding a Realistic amount of Water, doesn't that mean the Same amount of Vapor can be Produced at a Lower Temperature?
I wasn't sure I was ready, but because of the information presented in this thread, I gave it a go and found it rather pleasant. So much so I purchased another Pico, as that's the only TC device I have that will do SS. I don't see myself using anything other than SS, but then again, I didn't think I'd jump on the TC bandwagon either.
Tap water comes out of our faucets at around 110f-115f.
It's a Board of health requirement for all public kitchen and bathrooms.
I just calibrated a thermometer and my tap water is 123f.
I stuck my finger under it and it was not that hot to burn or blister..
Do you trust your readings enough on your IR device to touch your coil during that experiment????
I would not do it..
I have done it by accident...was not fun and it blistered to a 2nd degree burn.
Right now, I'm trying to learn about Arctic Fox. If I ever figure out how to download and use it, I may start there. Thanks, @sofarsogood
This was a Russian 91%, built up like a carto on steroids. It was vertical NI200 coil, and back in those days many of us (credit to @DJ ) were using Hemp as a filler. I know it was fully saturated, and I know it wasnt a dry hit situation. You can see the vapor trailing off to the right as I had a fan blowing on it.
Now after snapping these pics, I put the tank back on and vaped it, as is without changing anything. That build was a very satisfying hit.

The temperature reading the the vaporized e-Liquid coming off the coils and not the temperature of the metal itself. You can't breath vapor that hot or you would get seriously hurt.
Burns in the trachea from inhaling hot gases are a common occurrence and threaten the
recovery of fire victims. Inhalation injury is also one of the most common causes of death,
especially among children and the elderly.
The last 83 pages of posts were not about the temperature of the vapor produced, but about the temperature of with metal wire in the coil. That is where thermal breakdown products can occur, not in the vapor after it leaves the drip tip. 116F is a moderately warm vapor and does not reflect coil temperature. It is the coil temperature that's the issue here.
95W and 500°F in TC mode
I don't have a Gadget that can Accurately do Non-Contact Temp Measurement on Coils.
So I put a SS Spoon in Boiling Water for about 5 Minutes. Then Pulled it out, using Tongs, and dropped a Drop of my Day2Day e-Liquid on it.
Didn't see much Vapor coming off it.
Just Say'n.
Going to be lots of vape devices available for me when you all give up vaping believing these made for the result they wanted studies.
I'm not giving up Vaping....but if studies really find out it's safer to use TC, I'm going Stainless... the only thing I will really miss is my Nautilus Mini unless they come out with SS coils.
Without opening another can of worms I've noticed in your posts you use Nickel wire. Why that over SS. Isn't SS safer?This was a Russian 91%, built up like a carto on steroids. It was vertical NI200 coil, and back in those days many of us (credit to @DJ ) were using Hemp as a filler. I know it was fully saturated, and I know it wasnt a dry hit situation. You can see the vapor trailing off to the right as I had a fan blowing on it.

Idk but Ni kinda scares me a bit...The Nautilus mini TC coils are only Ni, that's why I'm asking. I'm sure others are wondering which way to go in TC wires..
Those photos were all back in the beginning, DNA40 days. NI200 was the only known wire at the time. TI came next, SS came later. I have been using TI for the last year or so myself, but after building a SS coil for a friend today, I may give it a go once I find some SS430.
Are we to assume from the studies that the vapor hits higher than 470f and is instantly cooled by the air flow before it hits our lips and in our mouth? If I use my Narda RDA (clone, could not find the original, dont hate plz) my mouth and tougue remain cool. The distance between my mouth and the coil is less than 1cm. At 31watts 4.2 volts .57 ohms. My vapor is cool.
So either it has hit the higher 470fand has been instantly cooled due to the tiny air flow it has or its not hitting high temps. Which is it and why is it so hard for scientist to accuratly test these things with all the equipment they have?? Are they really looking for the truth? It seems like the only people that are looking for the truth are people in this thread with a serious lack of equipment and a lab.... (and me personally, a Science degree)
Has anyone ever opened a commercial convection oven at 425f? Your whole face feels that blast of heat from over foot away!??
Just another observation.
Don't forget about evaporative cooling in your sciencing.
I'd give Plain Old SS316/316L a go if you have Never Tried it.
Clean Taste. Fast Ramp Ups/Downs. Inexpensive. And you can get it about Anywhere you can buy Vape Wire.
