A candle's burn time will be dependent on it's environment. Temperature, airflow and oxygen all play a role in the burn time of a candle.
100% pure Canadian beeswax, cotton braided wick.
Black candles are coloured using vegetable dye.
Always burn on a heat resistant plate to catch any dripping wax. Trim wick to 1/4" with every use. Allow candle to burn evenly across the diameter of the candle, especially the first time burning. For pillar candles roll in edges to avoid tunneling.
