Nice post up there Dave I do blend for a couple reasons: 1) Try to find a product that fits both my wicking, asthetic and HT wishes 2) If a wax lacks in HT but burns great, I'd like to add a helper paraffin 3) If it burns a little oily or is too transparent, I'll add a little soy. If I want to do that and not mess up the characteristics of the major wax, I need to know if it already has some soy, is designed to pull away from the jar (so I add a helper of the same type) or vice versa. If not, I'll have wet spots like crazy. If you might have read the archives on CBL130 about 1 1/2 years ago, I may as well have been a hired spokesperson for the company. I loved the wax and was all set to sell. I was still working out of my kitchen at the time where the house temp on this level wasn't too cold or too hot. But something happend to my beloved CBL130. It lost its HT. I bought another slab...no HT. A fellow chandler on this forum bought a slab....no HT. When I emailed with Bill he told me the reason was the high soy content of CBL130. OK...I can work with that, I think. What is a challenge is whether this wax is like J300 or IGI 6006 which makes a big difference what helper wax I put in it. So, I ordered a slab to try to figure this out and maybe it will surprise me and have HT once again. I did not order a slab of CBL125 because I do feel it is close enough (if not the same) as IGI 4630 so it's fairly easy to replace, if needed down the road. I doubt that will happen but I don't want to start over again. This wax testing isn't any fun anymore.
