I'm using Nature's Garden NG Soy Wax. And the HTP 1212 wicks. I managed to get ONE blueberry muffin scented candle in a wide mouth mason jar to nearly melt completely and leave no residue, but that's the only one. And I've gone through a 50 pound box of wax trying. I'm starting to wonder if it's the wax. I've used a zillion different fragrances and I can't get any of the candles to get a good hot throw. Not a single one. And I adjust the FO, sometimes more, sometimes less, and still not a good hot throw at all. Yet, the reviews on the site say that everyone else seems to be getting a good throw. LOL! I called NG about the problems, they have a help line. First time it was "get a bigger wick". I did that. Then it was "the fragrance is too thick" even though it was an NG fo, so I tried a lighter one. Now it's "it must be the jar." But they are just mason jars? I know candle making is try, try and try some more, but I'm wondering. I've GOT to be doing something wrong! The wax instructions are to heat to 175, add FO at 130 and pour at 110. I do that, exactly. Still nothing. *big sigh* Getting so frustrated LOL
