Linds

I am experiencing the same! I am still new/inexperienced, but these are the things I've tried: Pouring cooler or warmer (have tried pouring at 110, 130, 135, 140, 150) Warming containers Not warming containers Putting poured candles in a turned-off oven to set overnight (tried this with latest batch, bad sink holes). Wrapping poured candles with a towel and letting them set in a roasting pan Of course I started out just letting them set at room temp, so I've done that too. Locking wicks in place tightly Leaving wicks more loose (to try to let them release air) Some details: My kitchen (where I'm working) is usually 70-72 degrees without the oven on. When I turn the oven on to warm containers, the kitchen warms to about 75. On a previous batch, I had poured at 135 and only had one sink hole in the last container I poured. Assuming the wax had cooled a bit by then, I decided to try pouring just a bit warmer. So, last night this is what I tried: 9oz. straight sided jars, 2.5" diameter, 464 melted and heated to 185, poured at 138-139, into warmed containers, various wicks - brands and sizes - for testing, no fragrance or dye added. BAD sink holes! I noticed a few small bubbles on the bottom of the container around the wick tab. I have been using glue dots to secure wicks, and I'm wondering if the space they leave between the container and the tab isn't trapping air. I pour slowly but always, always notice bubbles as the wax cools.
