When burning your candle for the first time it is important to burn it for at least two hours, or until the wax becomes level with the jar. This is called a full melt pool and is important for the longevity of your candle. Soy wax has a "memory" and will burn to the same melt pool as the first time it was burned. This is why your first burn is so important! If your candle is tunneling you may not have burned the candle long enough the first time.
