Thanks for the tip. What would you say to the coil being 'gunked' (that is, mildly burnt taste) no more than 5 minutes after rewicking...every time? Here's what I think happened: Wick was too dense to draw liquid into the coil. Inside the coil, liquid was scorching (the wick is totally unharmed btw). There's definitely a goldilocks amount of wicking to achieve. Other variables to consider are the absorption rate of the wick and the viscosity of the liquid as well as the ingredients in the liquid/wick (simple sugars will burn/caramelize really easily). So I conducted a little, totally unscientific experiment. I placed a drop of 100% VG (no flavors, colors, etc.) onto pieces of Japanese OC, Some wispy organic cotton ball thing (given me by another vaper), and a bit of dental gauze (daughter had an extra tooth extracted [no, really]). Materials were approximately the same size and thickness. Observations made when the drops first touched their respective materials, and again an hour later. Results are as follows:
Wispy ball cotton: Never fully absorbed. Surface tension was broken at the bottom of the drop, but it never spread.
Japanese organic: Absorbed in relatively short order, about 10 seconds. Final diameter of spread about twice the size of original drop.
Dental gauze: Near instantaneous total absorption. Spread after 1 hour was so great, the gauze appeared to have never had the drop of VG.
I am quitting smoking, so even with 24mg WTA unmixed, I'm chain vaping. For me, the Japanese worked alright (better than the cotton ball/bail) but I still had issues. Guess what's in my coil now, and hasn't scorched? Since I'm chain vaping, I NEED the wick to truck the juice in. I don't have time to wait. I need the wick to wick quick! It makes since to me that the gauze works so well, it's used for wicking blood, plasma, etc. What surprised me is how quickly the gauze lets it vaporize. It's also super easy to wick up a coil with it. I'll chime in about longevity after it's kicked the bucket.
