Sorry about that. I should have provided details: I use either 1343 or 1274 for my rustics, and only 1/2 ounce per pound FO. Sometimes I use 3 TBSP stearic and sometimes no additives. The cooled melt pool will mottle every time. Most of the time the white spots are not that noticeable, but sometimes they really spoil the look of a partially-burned candle. I also have that same problem with scented chunk candles. (See photo below.) After the melt pool cools, mottling appears on top. In this case I wouldn't want to add a bunch of stearic and vybar because it would reduce the translucency. TopofMurrayHill: I didn't realize that microwax will eliminate mottling. I've heard UA will do it, but I'm afraid it will reduce translucency on the chunkies and interfere with the finish on a rustic. Does anyone know?
