Because 450 is a completely random number. That's why. And it implies hat you need temp control to be safe. Which may not be true.
I don't understand why you are continuing to argue for 450 when it's an arbitrary number.
No I wasn't implying you think vaping is evil. I was suggesting that if you're bother enough byfkawed science to set an arbitrary number your mind may be more at easy if you don't inhale or stop vaping all together.
There's no information that nasties are present in an ecig as it's vaped by members here. There is flawed science showing if you vape how their chamber is setup with that flawed heating and flawed airflow nasties far lower than those of smoking may be produced.
There is no information showing you using a vape at 450 with stainless wire is less harmful than using an ecig which wicks properly with kanthal and no temp control.
You've got it in our head nOw though it seems. That 450 is a magic number to be safe. It's not. It's the temp they observed if their liquid in their chamber and holds no bearing on vaping whatsoever. I really don't know how else to communicate it so I'll Stop here to
Avoid your frustration and mine.
The bottom line is the comparison is like this.
If I heat pickles in a pot to 500 degrees over the course of an hour they emit toxic chemicals. So don't eat cucumbers.
Yes. It's that relevant. Which is to say not at all.
And that's before we discuss how inaccurate temp control is or what point the measurement is taken.

Given the right circumstances you can make anything toxic. That doesn't relate to my vaping style. If I heat a coil with no liquid carcinogens are expelled from burning cotton. I don't vape empty tanks. Same thing.
Either you live in a world of science and scientific method must apply or you base things on anecdotal evidence which likely holds no correlation. I choose the former.
Yes, I am a proponent for temp control. However, if you look at what I have done is this thread, I have spent a lot of time and money doing technically sound testing for those who dont have Temp Control, and presented ways for them to keep their temps down. Maybe I should just stick my head in the sand and say to hell with everybody.
I am using 450 as what I "personally" would consider a reasonable limit, and that is pushing it past the point where VG starts to degrade into nasties.
The study actually started to detect nasties at 410f, and that is not an arbitrary number, that was a repeatable measurement by scientific grade instrumentation, but the ROR didnt escalate dramatically until 450f. The 410f number is science. Heat VG to 410 and it starts to degrade and formaldehyde is a by-product, or at least that what Wang said. I dont care whether it was in a reactor, a tin cup, or a pot on the stove, heat vg to 410f and it gives off nasties.
Previous to this study it was a known and accepted fact that Glycerol decomposes into acrolein at ~535, now I agree that you can start tasting it at about 505F so vapors are not likely getting that high.
But vapors are going above 410f.....
