OK, so I decided to do my first round of wick tests sans fragrance or color. I'm using KY125 in an 11oz apothecary, poured (slushy) just below the point where the jar begins to narrow. I have the following wick sample packs purchased from Bitter Creek... RRD HTP Cotton core Paper core Zinc core I have tried every wick size in these sample packs. I have single-wicked, double wicked, and triple wicked trying to get a full MP in the proper amount of time based in the diameter of the jar (approx. an inch an hour). I have YET to get a full MP in approximately three hours...it's either no full MP at all or a full MP in about 30 minutes. In addition, almost every one of the wicks, regardless of the type or how many used, is mushrooming. I thought mushrooming was caused by a too-heavy FO for the wick used or too much dye. As I'm not using fragrance or dye in these testers, why am I getting the mushrooms??? I'd appreciate any suggestions, thoughts, or H-E-L-P anyone would be willing to give. Thanks! Sherry
