Hi, I actually went with IGI 1230 Straight Paraffin, not sure why, and now wish I hadn't. This stuff is rock hard! Not very attractive either. Almost translucent. I added about 1/4 teaspoon of vybar to a pound of wax. Heated it to 190 degrees, added 6% FO, cooled and poured. Okay, it has awesome CT and awesome HT if using it in a tealight tart warmer. Bad news, I couldn't get the tart to melt in my 15wt. plug-in. I'll still use it for tealight warmers. It's not easy to work with, kind of ugly (I didn't color them), and didn't work in what I had wanted it to. So onto something else. Maybe I'll try adding a little J50 to some. If you try the 4794 with 415 for clamshells, let me know how it does. I will probably try it next, but I have 9 pounds of this stuff to use up first. I just don't get it. Scentsy can makes a wax that melts in one of these warmers, and I can't figure it out. That's what started this whole thing. I bought a Scentsy warmer and loved it. Then found something like them from BCN. Thought, hey I can make my own, cool. Not so much. I really don't know what direction to take now.
