The first burn of any candle should be least two (2) hours or until the entire surface has turned to liquid wax. This will ensure a prolonged the life of your candle. Never burn for more than 4 hours at a time, and never burn a candle where there is less than 1/2" of wax left.
For optimal burning, always trim the wick to 1/4" before each lighting to maintain an even and clean burn which avoids smoking and overheating. Extinguish your candle, trim your wick, then relight if the candle repeatedly smokes, the vessel gets too hot or the flame becomes too high.
Avoid burning where there are drafts and air vents. Always keep candles in sight when in use. Extinguish your candle flame when leaving a room or going to sleep. Keep all candles out of the reach of children or pets.
