Wondering if anyone else is having this problem. I'm using CalCandles CocoBrite with 464 Soy, 3:1 ratio. I've been wick testing and I've found that the burn from several of the wicks causes the wax to turn from white to a light tan color. Even with candles that are clearly under-wicked I get the same effect. The burn pool and surface become tan and the rest of the unmelted wax is the original creamy white. It looks terrible! It seems to happen most with CD wicks but is also a bit of an issue with ECO wicks. It looks to me like the heat from the flame is oxidizing the warmed wax. Any suggestions on why this is occurring and how to correct it? After many, many tests I've found the ECO wicks burn the best, but this discoloration is a real problem!
