THE FIRST BURN
The first burn is the most important. Make sure the melt pool reaches all sides of the candle before extinguishing, otherwise tunneling can occur.
Try to make a habit of letting the melt pool always reach the sides of the candle to ensure you capture the candle's full burning potential. Never exceed 4 hours of burning.
TRIM YOUR WICKS
Always trim your wicks to 1/4" before every burn to ensure the candle does not burn faster than it should.
