What Caused The Evod Silicone Insulator To Scorch?

I have been using an evod for two years now. Yeah, I know, minor leagues, but it gets the job done just fine for me.

For the first 18 months I was constantly buying new coils. I work from home so I can basically vape all I want and I vape A LOT. I use Swagger as my ADV and it will destroy a coil in just a couple days. It was becoming difficult to even find coils to buy and it was getting expensive, so I did some research on rebuilding my own coils. At first I tried to build them with silica wick, but I could never get them to work right. Using 1mm silica wick wrapping around a stick pin the wraps would always be too big and there was lots of leak/gurgling. So I went the cotton route and would wrap around a 1/32 drill bit and then slide the cotton through the coil. Works great, perfect ohms, great flavor. I've been doing this for the past six months. In the first 18 months of vaping I never got sick once. Since I've been using the cotton wicks I've been SEVERELY sick twice (probably a respiratory infection but never went to the Doc), and now I feel like I'm getting sick AGAIN.

I've noticed that I can see little flecks of what looks like cotton building up on the mouthpiece, and I'm assuming, going into my lungs. I think this is what is making me sick--the buildup over time. Anyone else had issues with this? I think I may have reached the end of my rope with vaping and now maybe I'll do what my original intention was (quitting altogether after vaping for a short period of time).

Anyone have any tips on rebuilding coils with silica? I've watched a million Youtube videos and replicate the process perfectly, but the wraps end up being twice the size they should be and I've been unable to slide silica wicks into the coil like I do with cotton because even at 1mm it's too big to fit through the hole. Thanks for any help.  

Hi,
I'm posting because I just encountered some silica wick on ebay while looking for pre-built coils and different kinds of pre-built wire.
I've only used cotton so far- gonna get some rayon eventually but I think I'll order some from USA, people here in UK buy the rayon in bulk from US and resell it by meter for ridiculous price. And whatever material Smok supplies with their RBA heads for TFV12 tank (I must say this material was pretty good, used it both in smok tfv12 rta and berserker mini rta, wicked well, tasted fine and lasted slightly longer than my normal muji cotton. It's gone now so I can't post a picture.).

Anyway- I tried to research here about silica wick but the latest posts were from 2013. Same on youtube- bunch of old videos. Found a thread with a few posts on reddit from like 3 years ago with some folks saying they still use silica wick, claiming the taste is cleaner, you can't physically burn it, you can dry burn it, lasts longer etc.
Why is it not popular anymore, why has it disappeared? Is it worth giving a shot? What are the disadvantages, as clearly there were some advantages I found, but there must have been a reason for folks to abandon this material (other than the one mention below)?

Wicking the coil itself is not a big concern for me, I've read about trouble to get it through a coil and I think I know how to deal with it.

Thanks  

I haven't seen this discussed yet, so I figured I'd announce my discovery:

I use a Kanger EVOD single coil tank, and a non variable voltage eGo style Kanger battery.

When I vape PG, it tastes like a grandma ultra light if I don't use a 1.8ohm coil.

But these 1.8ohm coils burn out instantaneously if I put VG in.

To vape the thicker VG, the 2.5ohm coils work wonderfully.  

So a juice im using is gunking up coils quick. I hate dry burning (it leaves a bad taste no matter how careful I am) and I've read you can re wick it with 1mm wick.

I heard ekowool is good, will that work? if so, what kind do I get hollow,cotton core or silica core?
And would I have to boil/clean the wick before I use it?

thx  

GS Air coils/GS 3ml tanks.
I Googlefied this and Did see One place that said A worn out tank could make coils not last as long. (Sounds near fetched to me...)

Can an old tank start Causing premade coils to show Low ohms, like. 05 ohm?

I am pretty sure these are factory coils not FT copycats.

I have an Evod with a rebuilt coil (japanese organic cotton) and was wondering if I could vape high VG juices in it. I use a VV twist battery. Possibly?  

Hey guys, I bought the Subtank Nano and loved it with the packaged coils.

I bought back-up coils that had a white insulator instead of the red, and the first one I popped in gave me such a severe sore on my tongue that I can barely talk. Both of them I've bought have really made it so bad and the flavor isn't good either.

I think they're clones that really have some bad coil material or something, but I can't tell... do the authentic ones have the red insulator?

Thank you!  

I've got one that has me puzzled. I went through two fills of my Aerotank V2 with Cosmic Fog's Milk and Honey when it started to taste burnt. I figured no big deal, let me change the coil and clean the tank and all will be well. Well, new coil and cleaned tank and about 4 drags in it tastes burnt again. Thinking maybe I have a bum coil I try another one. Same deal.
I'm at a loss. It's the same bottle of liquid, same tank (cleaned each time), same battery (iStick 50w), same wattage (8.9), same resistance (1.2 ohm). Anyone have any clue what's could be causing this? It's getting expensive in coils and liquid!

Thanks  

Okay so I bought a pack of 5 coils from FastTech as I needed some coils, they arrived today and well.. they don't really look too good. there like barely any wick on them! and the rubber seal thing on it is tiny.. all I need to do is just look at it and know it's going to just leak and gurgle and ew.
Here's a pic;

Should I put a bigger rubber seal on it? There's barely any silica wick on these things I'm quite disappointed really.. Don't know what I expected ordering from fasttech but not that!

Any ideas on what I should do with these? :/  

I change my coil infrequently,I notice sometimes when I rewick or change flavour on my rta,my coil looked black and gunk.After I rebuilt it and used it,the favour is ok and no dry hit, just a little less flavour.Recently,there is people contracting Vape related illnesses and a few died.I just don’t have too much time recoil and built,as usually rebuilding my rta which is relatively new released would take around 20min and I don’t have the time.Is dry hitting dangerous for the health because of Formaldehyde of dry hit or is the risk low?
What’s actually risky vaping nicotine,PG/VG only?
