essential depot pg/vg ejc labs nic?

Curious, what were the circumstances when your coil ignited? how long did you fire the coil before it ignited? did it ignite after one firing or after multiple firings? what wire gauge and at what resistance and wattage? what wick material and was there adequate amount of it. was it primed properly? was there adequate airflow and eliquid? What flavoring and does it have alcohol as a solvent? did it ignite while you were taking a hit from it or were you watching the coil?

All good questions. First off, it happened on three different coils neither of which had hot legs. Therefore the possibility of a bad coil is out. One coil was 30 gauge Kenthal 6/5 (or 5/4)wraps on 2mm. Another was 28 gauge 6/5 also on 2 mm. Resistance between .9 and 1.3 ohms. Cotton wick fully saturated with unflavored Nic, 80%vg, 5% distilled water, 15% Pg. I was pulsating the coils to get rid of the fresh cotton taste. In all cases ignition occurred on third or fourth pulse, each pulse approx 3-4 seconds at a modest 10 watts. I did feel some intense heat a couple of times while vaping - pretty sure it was fire, but not certain.

One possible factor might be the possibility that my cotton was not quite touching the coil - a sure recipe I am told for spontaneous combustion. I did an experiment by heating 1 ml of VG in a tea spoon on top of the stove, and it ignited in 10 seconds on high heat and 30 seconds on low/moderate heat. BTW, this has nothing to do with Essential Depot. All VG behave the same.

Of course, why should they enlighten the consumer?

I suppose they do not want openly admit they cater to vapers also.

If your coils dont have legs, then how the heck are they mounted to the posts? and how does this eliminate the possibility of a bad coil? You could have a hot spot in the coil still even with your legless coils... Basically you seem to be on a Ejuice is bad and dangerous and flammable kick here. Enjoy that. I think you just unintentionally had a bad coil.

..... Sorry, that was an omission on my part. Should have said NO hot legs. The rest of my coil was fine as well - no hot spots.
As for the rest of your comments, you show clear signs of being unwilling to listen to any other view than yours. I see that all the time with people who have a vested interest in things - vaping establishment for one. The minute they hear something remotely considered against their interests, they start a propaganda campaign. "We take many risks in lives, so adding one more, should not hurt." Nonsense; I have a legitimate issue with flammability, and if you are hooked on vaping to such an extent that you do not want to hear the facts, then that is NOT my problem. It's yours.

dafuq??

dafuq??

I am not on any sort of a "kick" as you seem to imply.

 

[EverPresentNoob]

ok. My bad. reading through the thread that was simply the impression that I got. Lighten up, this is only the internet.

Try it without the distilled water in the mix. Replace with .9 saline if you want to dilute. I found the one juice I put dw in provided a really hot vape.

FWIW I exclusively use essential depot max vg mixes with NN vg nic at 75-80 watts on a fused Clapton coil and have never experienced it flaming up on me. FUD is FUD.

Judging from comments I have received in this and other threads, fire is caused by the tinniest gap between the coil and the wick. Cotton tends to settle down when wet, allowing liquid to accumulate inside the gap. I will just have to use more cotton in the future. Thanks guys.

 

[satchvai]

Ahh. The old wicking issue. I agree that can be tricky. Glad you found an answer.

Yeah, "we" were always tought to use only the slightest amount of cotton, since it sweels up when wet... However, that juiced up cotton and airflow are the only things that cools down so that we don't burn the wick(or juice) and with heat, I believe cotton retracts as pressure builds up, and we need to account for that when wicking...

I had for a long time gotten a bad taste from many of my builds in the beginning, and when searching for a solution, then it always seemed to be too much cotton, so I used less and less and it just seemed to get worse... Then I saw some more youtube videos where they wicked it way tighter than i've ever did and when I tried that(not tight, just some more resistance than before), then the issue went away. Of course there's a balance with this and too much is just as bad as too little!

Also, the juiced up cotton acts as a heatsink in the coil, so if you have trouble with too hot coils, then up the id... For rta's i'm going back and foreward between 2.5mm and 3mm. In the subtank mini, 3mm is nice since it is a really hot running atty with that tiny reduced chamber, and with all the water i'm using, then it helps very much to use e.g. 3mm coils...

Thanks mehrtz, It was your post in the other thread that alerted me to the the fire's cause. And you are right, cotton does subside, retract or shrink with heat.
