AMD, sorry, I've been having computer problems and have been away.

I dunno if you ever got the Squape R thing straightened out, but that sucker likes to be wicked TIGHT! For some reason, that particular atty seems to be more sensitive to coil burn than all my other atties. So when you get that burnt taste that won't go away no matter what, try packing it a little tighter - unless it smells like burning paper, it's probably coil burn. Also, when you tighten your tank after filling, back it off a little bit. There's about a quarter turn's worth where it turns freely - I think that's your juice flow control. You can play with that, and also, if you need to get a lot of liquid on your wick quickly, try turning it back and forth - it's like pumping liquid in.

Okay, as my tank got low, and my Fogger is my nightstand atty, it is tilted constantly and I got some leakage. So I think I need to increase the density of the tails a bit. Ruined my coil trying to remove the wick, so I have to rebuild it today.

I should really just retire the darn thing, but it still works and is just a PITA to work with.

I hear you there. I had one with very little liquid laid on its side for a while, that definitely was laying in a pile of juice when I finally picked it up. It does fine vertically for me, but if even one of those juice holes aren't completely submerged for more than a few minutes, all bets seem to be off.

That's one of the things I like about my Foggers: they vape great with wick in the channels, and with wick in the channels, they don't flood!

I don't put much wick in them, but with Rayon, it doesn't take much. I leave my iStick/Fogger on its side to charge overnight, and it's never flooded in that amount of time. Of course, I turn them upside down for long term storage.

22g kanthal wrapped with flat ribbon, reverse wrapped with 32g nichrome. Dual coil .18ohm surprisingly it heats up instantly, just holds on to that heat lol.

All of these with safe 100% rayon wick

I did a total of 3 re-wicks tonight. My coils seem to gunk faster than the actual rayon wicks :) Nasty looking coils, but the flavor wasn't tainted like on cotton -- it was more the color of the liquid in the tank. There was a slight drop off in flavor only in the Orchid dual coil build. I did manage to get an extra refill out of the KFL clone, at least before the coil went black, so that's good. And man-o-man, it was charred to a briquette. But the flavor was true, which was amazing.

I went back to a smaller diameter coil in the Fogger this time, just because a 2mm ID is easier to work with than a 2.45 mm ID. Didn't have any issues with the installation.

I think I see a 3lb box in my future :)

I've been using an RM3/A6 dual coil the past couple of months. Very intense flavor. I've settled on 28gauge Kanthal, 2mm ID, .3-.4 ohms. I use 6mg.

Well, last month I purchased a CLT bottm feed. First build, even with tightening the air way down, not much flavor. So, I built down a bit, trying to get there with some improvement. But, still going back to the A6 as my daily driver. Yesterday, I thought I'd try my first "fancy" coil. I wrapped two strands of .6mmx.1mm flat around 26 gauge kanthal by hand then rolled 2mm ID, .2 ohm:

Much better flavor, but still not quite where I'm happy. But, oh my, the nic hit and throat rape. The only way for me to run something like this is to step down to 3mg.

Yep! 99% of the time it is coil burn not wick burn. Coil will get hot and burn the juice in it. You get a burnt taste that doesn't go away for a while with out intervention. I'm going on two weeks on my current build in the flashi. Switched to dripper mode for the last week and a number of times I didn't drip when I should have and ran the coil dry. Got the burnt hit and coil was fouled...

98% of the time I can redrip to get the coil wet and take a thin folded paper towel or a qtip and wipe the outside Diameter of the whole coil, removing the carbon burnt juice. Drip more and its clear and ready to keep going and going.

The rayon is always fine its the overheat of the coil that Fry's the juice to the coil.

In that situation I would have just added a little tuft at the channels. Either right in the channel or under or over the existing tail. I mean a very small light tuft of rayon wick. When the rayon is wet it will stay in position .

Really don't have to do an entire rewick. You can mold it like clay. Ad, remove, layer, trim when needed.

My coils have never actually gunked with a proper wick like they did with cotton. It turns black at 6v but thats normal at high power on a vv. You may be wicking too loose or too tight... Have you ever wicked tight enough to taste the rayon? You want to be just shy of tasting rayon on the first few hits.

Jeremy, wondering if you could edit the first post to include some of the more recent info? It's the reason I ordered tencel because I didn't read far enough to find out it wasn't as good as regular rayon. And it might curtail some of the repetitive questions. Just a thought

Others have asked the same.. My blog will quickly take you through 1200 posts with only important info.

http://www.e-cigarette-forum.com/forum/blogs/jeremyr/6502-rayon-research-posts-up-post-400.html

Here's part of one-

Unless you're educated in organic chemistry, you're not going to comprehend the manufacturing process and the solvents used. If you research on how every chemical you put in your body is synthesized, then you wouldn't take medication, only drink water, and only eat fruits, vegetables, and meat you kill. If you're sincerely worried about the solvents used in the manufacturing process of rayon then I suggest you don't do the research because I gerentee you ingest products that uses chemicals in the process manufacturing that are much more volatile to the human body.

Tencel *Top - is like ramie *top to work with, if you've tried that. There are guys that have success with it.

I still stand behind rayon being safe to use. Also I've been doing a lot of research to see if I can find tencel in that same cut.

Here's some comparison pics so you can see the difference...
Rayon coil on the left* - tencel top on the right.*

Tencel 'top'
null_zps2b4486d0.jpg


...

The caution has nothing to do with the lyocell itself. Only the dyes & such it takes to make garments out of it.

Just adding clearification.

It's the cleanest non tasting wick ever.... And traditional rayon is geotex certified free of harmful chemicals and tencel/lyocell is made with an evironmentally friendly non toxic process.

When I get time I will put the chemistry together on it. Planning to show the chemical reactions that take place completely remove the chemicals from the rayon fibers and all that's left is the cellulose in an atom chain. These processes and reactions are at the atomic level. Pure to the atomic level. That's why it tastes so pure. That's what I'm looking to prove.....

Here is a description of the chemical process.

Treehead - have a look....

Rayon Fiber - Rayon Staple Fiber, Rayon Textile Filament Fiber, Rayon Industrial Filament Fiber


An In depth research paper - go to page 33/18

https://smartech.gatech.edu/bitstre...1E60C1DBEC10D5F555BD2E93D11.smart1?sequence=1

"In this process, cellulose will be regenerated into cellulose II, and carbon disulfide and H2S will be released."

Lol as you know rayon doesn't melt.. that's nothing but Mis-information.... That keeps people from trying this incredible wick. I'm glad you all came on this journey with me, were laying the ground work for our fellow vapers.

It's weird the coil dry burns before the wick scorches.. Yeah I wouldn't recommend dry burning the coil by letting it dry.. Coil dry burn hurts your throat no matter the wick. So if every thing is chugging along great and you don't run it dry, you'll never have a dry hit.

All it takes is a burn test side by side with cotton.. Almost identical burn pattern...

@kiwi
Yes excellent, the straight fine tencel is great in straight wick devices like tiafuns, kangers, ect.

Doesn't matter, I read that a long time ago. Hemp and ramie and many others are degummed with strong acids including sulfuric.

Note - H2SO4 - Sulfuric acid, Formula

http://www.fibrafp7.net/Portals/0/Chongwen_Yu_Day_1.pdf

Hemp
• immersed in acid(H2SO4): 2g/L ,50°C, 1h
• Boiling: H2O2 :10%,NaOH:6%,Na2CO3:4%,
Na2SiO3:2%, urea 2%,JFC1%,85°C,2h,
or: Boiling only with alkali:Sodium hydroxide:10%,

That's what I finally figured out, don't trash the wick just because you get a burnt hit. For many months I was tearing down, cleaning and replacing the wick if I got a burnt hit because that's what I had to do with cotton. :facepalm:

What is that contraption? Is that a home made sqonker with a home made mechanical switch? If so kudos lol. Im getting ready to put a few builds together

No, haven't tasted the rayon on any of the builds. I'll try packing it a bit tighter then.

I was looking at that too, I like it! What that says to me is a big FU to anyone who would want to try and keep us from vaping. All that will happen is people will go underground to share ideas & resources and become very creative. Good job Verb! :)
