My test candles KEEP cracking in a circle around the wicks. The very first batch of candles I ever made about 6 weeks ago were BEAUTIFUL. But EVERY candle I've made since then (for wick testing) gets that damned crack around the wick. I'm pulling my hair out. Everything I've found during research says air bubbles in the melted wax or cooling too fast or both. If there are air bubbles in my melted wax, they're microscopic, cuz I see NOTHING. I stir gently. I tap the pitcher before pouring to release any invisible bubbles, then I tap the vessel after pouring for the same invisible bubbles. I pour slooooowly so as not to create bubbles.
I've tried heated containers, unheated containers, foil around the vessel, no foil. I've poured at 170 degrees (CandleScience recommendation), 165, 160, 155, 150. (Tomorrow I'm gonna try 145 and 140, a Flaming Candle recommendation.) I've cooled them on a wire rack (which CS recommended on their troubleshooting page). I've cooled them on a wooden cutting board. I've cooled them in my kitchen where there *might* be a draft or two just from people walking past, but I've also cooled them in the spare bedroom with the door closed and a Sterilite container inverted overtop of them. I've used a heat gun to melt the top 1/8" or so. The temperature in my house is a constant 73 degrees while I'm doing all this. And STILL cracks.
That first flawless batch was 100% GW 454 soy coconut wax. The second batch, when the crack started to appear, was also 454, and one of those candles cured with a fugly top. Since I also didn't like the fugly tops after soy candles burn, I decided to add a bit of parasoy. So now, my personal wax blend is 80% GW 454 and 20% parasoy (Blended Waxes brand BW 910). No more fugly tops now, just, ya know, that fucking crack. ðĪŽ
So, if anyone has any advice at all, I'd welcome it. Cuz I'm fresh out of ideas beyond just continuing to try cooler and cooler pour temps--and eventually, I'm gonna reach a temp that's not pourable. LOL I can't be a chandler if I can't get decent candles. How can I be so deficient at this? I've made nearly a dozen candles (one at a time) over the last week, trying one thing and another, and they crack every single time. Thanks in advance for any help you guys can offer. âĪïļ
