K..that was one I missed.
It 36ga is 27ohms per ft.
Srry.......if you send me the link I'll correct it............
I hate bad info

got ya. never did see a temp rating...
I hear that. I tested some fiberglass mat I had, with a ligter, and I had to hold the lighter in place for a long time. even then, it just melted...using a micro torch lighter, well over a bic temperature .

Glad you have that all figured out.
If you look at the McMaster Carr page McMaster-Carr
You'll see that the fiberglass is rated 1000* and then 1400*(option 2).
The silica is 2300*.
Ok, when nichrome wire just starts to glow red, its right at 1900* but we do hit it with a cooler blast of directed air, mist at the coil. Some do a "bright red" burn off. There isnt enough active thermal mass, the nichrome wire, to heat everything you listed, but trust me it will make that glass rope it contacts taste like crap. It does create enough heat to melt the plastic disk under the atty in a 510's air hole shut resulting in a lower draw and more contained heat. I have pics posted of it.
Butane & air burn at 192 ºC = 377.6 ºF.
WikiAnswers - What temperature does butane gas burn
A bic lighter produces what is known as a "diffusion" flame, where the flame front is where the air and fuel first come into contact and "diffuse" into the flame and then combust. These flames are much cooler than pre-mixed flames, as this need for 'diffusion' slows the reaction rate down.
If you are going to post "possible facts" causing someone to make poor decisions that may be detrimental to their health, pls do it somewhere else.
However, if an atty did ever see that temp, EVERYTHING around it would outgas and/or melt. Including the plastic bit under the atty it's self. I'm not so sure if that high a temp requirement is necessary, as much as it is desired , just to be sure.
I'm not going to try to correct everyones "ideas" continually. It just isn't possible. Sorry.
LowThudd, we are talking 3.7v and a total heat output of 4 watts on a standard atty (3.2ohms). You aren't taking the volume, airflow, mist spray and dead mass thats pulling that 4 watts away. Ok, my "guess" is I can lay my penstyle PV on a 40watt light bulb (10x the heat) and it won't disintegrate.
Yes, if the "loop & hook' or crimp method isn't used, the heat from the nichrome wire can and will usually fail at the solder joint. Its normal melting temp is abt 450*. Depends on the silver content. Much of the heat is conducted in the lead wire to it along with the liquid in the wick. The point of short circuit is the middle of the coil. It gets hot 1st, stays the hottest longest. The duration of use averages abt 5-7 sec on for most and much longer off. So less than a 50% duty cycle enters too.
I have threads that have the calculators posted.
Online Conversion - Ohm's Law Calculator
If you enter 2.5ohms @3.7v you'll see it will produce 5.47watts of heat while drawing 1.48A.
The "base" material? If you are referring to the nichrome wire, the resistance of the wire is in reaction with the electrons of the voltage applied. Just put any 2 values in the calculator and you can soon see the resulting pattern. Lower resistance or higher voltage results in more heat due to a higher current draw.
I did what I often do and neglected to read carefully enough. I looked for the loose knit not realizing that there were 3 different types of rope seals on that one page. When I was reviewing my invoice I saw fiberglass in the description and thats when I went back and figured out the error of my ways. I certainly don't blame anyone but myself for that bad, and was just passing the information back to the thread to hopefully help others avoid making the same mistake.HexKrak, if your order states Silica, I'd ask to return it for a refund as it does not meet the 2300* spec. It may cost $2 to return it, better than 5' of glass rope you don't want.
Great post! However, I hate to disagree with you, but the wicking material(hopefully) soaked in e-juice plays a segnificant rate of btu absorbtion. It doesn't seem to me to be as simple as you have pointed out, or there would be more health problems w/ vaping in general.
