For this wax I pour at 120 to 115 degree. The room temp is around 66 F. Its cooler area and fall is here :-). The weird thing is, it happens to random candles and not all. So I made 3 yesterday with cranberry scent and one of them got cracks and other two are fine. Same, I made vanilla nutmeg last week and one of them got cracks after 2-3 days and others are fine. I am thinking to buy wax warmer large one and put candle in there, hoping it would fix it?!!!!!
I dont know what would be the best way to do this.
