Question about vg thermal degradation

[Alphazero]

Hello,
I read in one of the posts here that vg in about 210c starts to degrade into toxic chemicals.

But what will happen if i mix vg with 10% distilled water? The 210c will go up or down?

Water will lower the boiling point and produce less of the nastys at a given temperature.

Mike Petro has tested a variety of these mix options and has some very useful information to help. Here's a link to one of his blogs that discusses this. https://www.e-cigarette-forum.com/f...ing-point-and-vaping-temperatures.7857/unread

Thanks.
Mike wrote that he vapes mouth to lung, but how? If he uses subohm vaping?
Plus he says that taking more nicotine per puff is safer, but if if add nicotine the throat hit wont allow me to vape comfortably.
Lets say i vape with pico tc mode, 90% vg 10% dw, how much temp is ideal? How can i add nicotine without burning throat hit? Mike didnt explain how should we scheme the best formula.
Thanks alot.

Resistance of a coil does not equate an inhalation style, especially on a regulated mod, where resistance doesn't even equate with power. Unfortunately, people have conflated the term "sub-ohm" with a DL vaping style. The happened back in the days when if you wanted more than 15-20 watts, you had to use a mech mod to get it, and then power was determined by resistance.

Plus he says that taking more nicotine per puff is safer

I think he means that smaller puffs, drawn less deeply into the lungs is safer, and that requires a higher nic level to be effective.

but if if add nicotine the throat hit wont allow me to vape comfortably.

People are different. The exact way of vaping that suits him best may not be ideal for me or for you.

Up to 450F should be pretty dang safe. The question is whether you really trust an Asian board manufacturer to have done sufficient homework to ensure that their TC numbers accurately reflect reality?

And then there's the question whether it's worth worrying about cabonyls at all, when we're pretty sure the levels are still several times lower in any vapor that doesn't taste burnt, than they are in smoke.

I use DW (10%) in my almost all VG juices (I am PG sensitive). I found that doing so, plus other best "not using TC mods," practices (although I am now using TC in at least some of my vapes, and have also started using PEG400 a PG substitute in my mixes, too) such as rotating setups not chain vaping, etc, to have benefitted my non-TC vapes (I have some drop in tanks I love and am not ready to give up, but don't have TC capable coils) a great deal. My tanks don't heat up at all, and before they certainly did. So, there are things you can do (besides TC) to keep vaping safer.

10% DW actually helped my vapes in general, including flavor which I was not expecting. It's certainly worth a shot if you are concerned. You could start low and slow by adding a few drops of TC to your tank. But, it's useful, and has a much higher boiling point than VG, ,which is how it lowers temps in tanks.

Best of luck,
