For optimal burning, we recommend burning your candle long enough the entire surface becomes liquid with each burn. This will prevent tunneling in your candle.
Before relighting your candle, always be sure to trim your wick to 1/8". This will ensure a longer and cleaner burn while keeping the flame under control.
Never leave your candle unattended while burning and always burn your candle on a fire proof surface that is clear of obstructions.
If there is less than 1/2" of wax remaining do not light your candle. Burning with less than 1/2" of wax remaining increases the chances of overheating of the vessel.
