Hi Jenn. I have only been experimenting with palm wax for only a couple of weeks but I'll share what I found so far. Your right, info on this wax is scarce! My biggest problem is the same as yours... a wick that will work with this wax. I've tried the cotton, the zinc core in different sizes and now I'm on a medium wood wick which I've had the best result out of all of them. The wood wick gave me the best wax pool so far. Like any other wick you must keep it trimmed to about 1/8" or you will have what I call a wild fire. My first burn on this candle lasted just over 4 hours. Last night I lit it for the second time and the wick looked short enough but i got that wild fire look again. I blew it out and this time trimmed the wood wick down to 1/8" and also cut it into the shape of a TP or upside down V. I did get the wax pool again but not as well as with the first burn as you can see on the side of the glass in the one picture. This container is 3" at its widest point.
Since patience is not my middle name I only waited a couple of days to light this candle after pouring. Plus I was so curious to how the wood wick would do. I actually poured two of these so I will wait another week or two to light the other.
I added Fresh Mango FO scent and the throw was not there at all unless I stuck my nose into the candle
It's probably because I didn't give it time to cure though. I have read online that with palm wax you only need to wait 4 days for it to be cured due to the hardness of this wax. Also, I have read comments that with the palm wax it's okay if they burn a tunnel down the center of the candle because that show's the beauty of this wax - the snowflake or crystal look and the wax will glow. During my testing, I have found this to be true. It's actually beautiful, at least in the yellow color. It makes me wonder how darker colors would look.
About those air pockets… I use wood skewer and poke down into the candle as far as it will go without any great force. I found one that was close to an inch wide in this one pictured. I kept poking around the area breaking up the top layer of wax over it and let that wax fall down into the air pocket. I usually keep a little left over wax just for this purpose or if a candle should need a second pour. I heated the left over wax to 205 (original wax was heated to 200) and slowly poured it into the air pocket and the rest over the top of the candle. After it cooled, you would never know that candle had a problem.
This is what I found in my testing and I hope it helps you in one way or another.
If anyone else has been experimenting or can offer some advice on palm wax and wicking, please post it and let us know?
