OK, I've got C-1, Ky parasoy for tarts (just got this in and have read it has changed, so not so sure about this one), Ky 125 cottonseed/soy blend, IGI 4794, Ecosoya CB 135, Ecosoya CB Xcel, J-50, J-223 and some straight IGI 2281. (I know, I know, I've got waaaay too many waxes, but most were smaller sample sizes to test with) I've read through all the threads I can find and many say to use a combination of paraffin and soy. Based on these waxes, where would you start? I mixed the 4794 with the CB Xcel 70/30 and got a good tart. I'm going to start testing it tomorrow and see how long it lasts. I also thought about mixing the KY parasoy with the IGI 4794. What are your thoughts about another good combo to outlast the "everywhere, in your face, at all the craft shows, givin' samples at the Fair" Scentsy clamshells.:rolleyes2 Thanks guys!
