I am trying to find the optimal balance between strong hot throw and my wax not turning a gross brownish color after burning. The candle in question is a vanilla cake candle with no color dye - 8% FO - and I’m trying various blends of 6006 and 4627 together with LX wicks, premier wicks and zinc core wicks. The more (paraffin) 4627, the easier the wax burns and the darker brown it turns. The hotter the wick (LX>Premier>Zinc), the easier the wax burns and the darker brown it turns. I’ve made so many candles, and I’m seriously struggling at this point. A 50/50 blend of 6006/4627 with zinc core wick provides essentially no browning or burning of the wax, but with a throw that isn’t strong enough for me. A 75/25 blend of 6006/4627 with LX 14 wicks provides great throw, but the wax burns and browns and starts to smell burnt and sooty. Why does this happen? Is it the vanillin burning? Is it the wax burning? Does anyone have any experience or advice with this scenario? I would sincerely appreciate it.
