I just purchased Accusoy 24 and tried pillars. What a disaster, but then I'm a newbie to pillars. Cracked from top to bottom, but then I had same experience with Naturewax P1. Thought it was just me but I searched and found that cracks may be a problem with soy pillars. Didn't find any tips, but if anyone has any I'd love to know. Some would crack after I burned the candle and it cooled. May stick to votives..........
