I use JOY wax, which is a soy blend wax, to make my tarts. I will warn ya ahead of time, that they are very soft, but do hold their shape very well. Scent throw is pretty awsome. I did that because JOY is what I started with. But since shipping is going out of this world, I am switching over to J223 for my containers (at least thats the plan). I also use the 6228 for my pillars, and since most people use the 50/50 mix, I figure I will jump on that band wagon too. lol.... Anway, if you want to try soy blend, I would highly recommend JOY from NG.... HTH:D oh yeah. forgot to add. I use 1.5oz per lb and never have a problem with seeping...
