Hello everyone! This is my first post – I started making candles a few months ago and have learned so much on the forums on this site, however, I've run into an issue that has completely stumped me. I'm currently making coconut wax candles (Coconut 83 from California Candle Supply) with two different custom-blended fragrances. One fragrance is 100% essential oils and I've had no issues wicking it (at least after A LOT of testing). I use a CD 6 wick in a glass tumbler that's about a 3" diameter.
The other fragrance is a blend of essential oils and fragrance oils (sandalwood fragrance oil, patchouli essential oil, campfire fragrance oil, and neroli fragrance oil). For some reason nearly every wick I've tested in this candle clogs after 1.5 - 3 hours. I've tried LX, ECO, and CD wicks. An ECO 4 wick works without clogging in a 4 oz metal tin, but all of the ECO wicks I tried in the glass tumbler clogged. I finally got a CD 10 wick to work without clogging, however, I got a full melt pool within 2 hours (which seems to fast) so I tried a CD 8, but this clogged. So I made another candle with a CD10 wick to make sure I could replicate my results and it clogged. Oy! Does anyone have any idea what's happening here? I only let the candles cure for 2 days before testing so perhaps that could be the issue? I thought 2 days would be enough just to test the wick (I cure for 2 weeks to test fragrance throw). The other candle with 100% essentials oils has never had any issues with wick clogging and I tested almost every kind of wick in that one and only let the candle cure overnight before testing. FYI, I use 7% fragrance in both candles and I heat the wax to 200 degrees, cool down to 150 before adding my fragrance, stir for a full 2 minutes, and then pour.
Any tips and advice would be greatly appreciated as I'm out of ideas here!
