Hello everyone, I could really use help if you can. We make Palm candles and we are having alot of difficulty whether we pour it hot or cooler that the top is hardening and then causing air pockets. When we poke through with a toothpick, there's quite a gap between the top and where it's still melted. We have used the heat gun to melt top but after 3 or 4 times, there are still air pockets. Any suggestions on what we can do differently? We greatly appreciate any comments. Thanks!
