Sorry, i don't want folks to think i'm trying to hijack this thread,but after reading
"dunno if I can take the taste of burnt cotton anymore" I have to share some advice i learned awhile back about organic fiber wicks.
I don't exactly remember where/who i learned it from, (one of the super senior ECF members) but cotton (and i am assuming any kiln dried organic fibers well) is dried to an extremely low moisture content. Meaning the cells themselves are completely void free water, and are 94% void of bound water (assuming they dry cotton down to 6%MC). I'm sure you've read here and elsewhere that organic fibers swell a lot, that's why. Where am i going with this? Well, with cotton use a lot less than you think is necessary (l took 1/2 away from what i thought looked right from my first build, and it helped a lot.) the second part to the equation: saturate the cotton with liquid, and let it sit long enough for the cells themselves to drink up. (usually an hour minimum for me, but overnight is better). When the wick is initially saturated it looks like it's ready for immediate use, it's not though. Within the first few seconds of heat all the surface moisture will evaporate and all that's left are completely dry and very scorchable fibers. Allowing the fibers to adsorb liquid to the point where free water is back in the cells creates in essence a heat sink, and scorching becomes pretty hard to accomplish. It's kind of like throwing a freshly cut green log onto a campfire (lots of sizzle and very little burn) vs. throwing on a piece of seasoned firewood that was just rained on (burns great after the surface moisture has evaporated).
I hope that helps out a bit, please don't give up on the organic fiber wicks quite yet.
That all being said, if i can get this wickless option working well, I would be really happy, and it would save a ton of time in DIY R&D
