It could be several reasons for the cracking, try pouring at a slightly lower temp and if you are pouring in a area of your home that is cooler (like a basement) after you pour your candles take a box and cover the candles while they are cooling, that slows down the cooling a little and may help the cracking problem. There are so many things that can effect your soy candle making. Your right about having patience, but keep trying and yes do alot of reading, and all candle makers will tell you that the most important thing is to test, test, test... but it is a fun and addictive hobby:rolleyes2
