It's fine it wasn't an experiment anyway. Sorry for creating this kind of stress.

Do not use polyfill as a wicking material that will come in contact with a coil, it will just melt into a nasty mess.
Thanks, that doesn't surprise me. I do plan on rolling the sock into a wick and trying that. I'm not sure of the material of it, woven cotton maybe?

There is a easy way to test fibrous materials. Set it on fire. If it burns to a grey ash it is a natural fiber if it balls up into a ball of burning nastiness it is a plastic. If it smells like burning plastic... it is.

Of course, I was selfish in that I didn't know about silk being a problem, and I don't want to give up my RBAs
(But then again, I am not going to try anything as a wick on a whim).
I understood it as expressing an idea that might be worth looking into. You did the right thing by asking here instead of just ordering to try it.
I'm really surprised by everyone who thinks drawn amorphous silica fiber is somehow bad. If someone knows how this misinformation is being passed around I would love to know.
To clarify
1. It is amorphous not cristalline.
2. The fibers we use are too large to inhale past the throat.
3. If you got some in your mouth you would just spit it out or swallow it.

Different studies have used different rules for counting fibers in air samples, but in general, a fiber is a particle that has a length ≥5 µm and a length:diameter ratio (aspect ratio) of ≥3:1 or ≥5:1. The WHO counts fibers as particles with lengths >5 µm, widths <3 µm, and aspect ratios ≥3:1. The National Institute for Occupational Safety and Health (NIOSH) counts fibers as particles with lengths >5 µm and aspect ratios ≥3:1. The levels of synthetic vitreous fibers in air are measured by phase contrast microscopy (PCM), transmission electron microscopy (TEM), or scanning electron microscopy (SEM) (see Chapter 7 for more details). A human respirable fiber (a fiber that can be inhaled and reach the lower air-exchange portion of the respiratory tract) is usually defined as a fiber having a diameter <3 µm.
...key determinants of toxicity including:
• The amount of material deposited in the alveolar region of the lung (fibers with diameters >3 µm do not reach this region; they are deposited in the upper respiratory tract and lung conductive airways, cleared by mucociliary action to the pharynx, swallowed, and eliminated via the feces);
• The rate at which macrophages engulf and clear fibers deposited in the lower lung (human
macrophages cannot fully engulf fibers with lengths longer than about 15–20 µm); and
• The extent of movement of deposited fibers from the alveoli to the lung interstitium and the
pleural cavity (fibers with diameters >0.3–0.4 µm may move less freely into the interstitium and
pleural cavity).
Fibers that can dissolve in physiologic fluids (i.e., that are less durable) develop weak points that can facilitate (1) transverse breakage by physical forces into shorter fibers and (2) faster clearance by macrophages, compared with fibers that do not dissolve, like amphibole asbestos fibers.
Synthetic vitreous fibers differ from asbestos in two ways that may provide at least partial explanations for their lower toxicity. Because most synthetic vitreous fibers are not crystalline like asbestos, they do not split longitudinally to form thinner fibers. They also generally have markedly less biopersistence in biological tissues than asbestos fibers because they can undergo dissolution and transverse breakage
I have never measured a silica fiber used in any ecig product that was smaller diameter than 8 µm, most were between 20 and 35 µm.

You keep changing your avatar. Everytime I read a comment and I think it is from someone I haven't read before, and I think, here is another good ecf member - then I check and it is you with a new avatar.

Bwahahahahaha
Bad choice of words on my part. I just didn't want anyone to try this just because it was mentioned. You never know who may attempt to experiment into the unknown without first investigating. That is why I said what I did.
Of course, I was selfish in that I didn't know about silk being a problem, and I don't want to give up my RBAs
(But then again, I am not going to try anything as a wick on a whim).
I know you can dry burn the nextel with no problem. Unfortunately I have not used it yet so I can't answer your questions. Did you read that entire thread, because the answer may be in there. If not, do a search of "nextel" on this forum and you'll come up with plenty of information.
One of the members said this about the stuff:
Well I have been using this nextel material for two weeks now. One on my large DID with just plain menthol and the AGA-T+ with the glass tank is for my cinnamon red hots liquid. And both seem to gum up equally but not a problem. My second wicks on both devices lasted me a week each. Well actually the wick with the cinnamon red hots is still going pretty good after a week. But the menthol one is already up to 5.5 volts and the flavor is just not there. So I replaced the sleeve on that wick and the difference is night and day. I absolutely love the clean crisp flavor with the new sleeve.
And the best part is no more messing around with having to torch wicks and stuff. It literally took me less than 2 minutes to pull the old sleeve and wire and slap a new one on and recoil it. Boy oh boy I'm in love with this stuff. Just got my order of 10 feet in the mail so I'm good to go. No more messing around with hot spots and all that crap. Just wrap the wire and hit the fire button. I have totally quit using the vivi nova's since I started using the sleeve.
Now I know I lead a sheltered life by only using this forum but I just can not believe that as good as this stuff is and as easy as it is to get a perfect coil each and every time that there is not that much hype about it. I keep searching youtube and don't find anything about the sleeving. So is it just a few of us here that are using it or what is the deal. I would have thought that this would be all over the vaping community by now.
Oh well I'm in love. Now I just have to get those nova's away from the wife and get her converted and we are good to go.
Although I haven't made a sleeved wick with the piece you gave me yet, Paulette, I did try torching it, because I wanted to see how much it stiffened up. It does tighten up a lot. It does still tend to fray on the ends. It has to be handled carefully. But once the coil is wrapped, and the juice keeps the Nextel wet, it should be ok. There are some RBAs where it probably couldn't be used, because of the space, like the DID. It has a 3.5mm wick hole, which leaves very little room between the wick and the positive post, and the large ground screw.
Well, I have finally made me one in my aga-s and it is working wonderfully. I am told it works even better after 1 or 2ml of juice has run through it. No hot spots and I get much better flavor than just with the mesh wick.
Where's the best place to buy some of this? I have an ATA-T2 that I'd like to try it out with.
Paulette, I would use unsized Silica fiber sleeving over Nextel which has a organic sizing applied : http://www.3m.com/market/industrial/ceramics/pdfs/health_safety.pdf
Rule62, The sizing is what makes the Nextel stiffen up when heated to high temperatures with a torch +2500F. With the sizing removed the Nextel should crumble fairly easily.

I didn't get it that hot. I experimented with it by torching a short piece to cherry red. It did stiffen up quite a bit.
Minimum order of 10 feet here (with $8.00 shipping): Nextel Braided Ceramic Very High Temperature Sleeving
or here --12" already pre-torched for $7.00 -- XC-116 Ceramic Wick - 12" Heat Treated
