Sorry for the late reply, I ran mine straight out the top hole on my ZAP, no folding. Stuck a blunt tip in it and wrapped a 4-5 coil. The Silica did good for about a week, but today I noticed it was getting dark and torching it didn't help make it white again. The flavor was starting to mute a little too, so I swapped it out with a 7x19 SS rope and it's performing like a champ. I think next time I place an order, i'll try the XC-18 ceramic wick (which is what I thought I was getting). Anyway, hope your ceramic is doing good, I had to many hotspots on my FC2000Z ceramic wicks.
