When you burn your candle be sure to let it burn until the entire surface, from jar edge to jar edge, is covered in melted soy oil. Soy has a ‘memory’ and if you blow out your candle before the candle has burned long enough to melt across the entire surface, the soy will remember and have a tendency to stop at that point the next time it is lit. This will cause the candle to burn down the middle, leaving excess soy around the sides of the jar. (Don’t sweat if it happens to you – just grab a hairdryer. One minute of low heat around the inside of the jar will be all it takes to get things evened out again! You’re welcome.)
