Maintain your candle
Never let the candle burn unattended for more than 2 hours at a time.
Always let the candle burn until the entire surface is liquid and wait until it is solid before relighting it.
If black smoke appears, cut the wick. It must be kept clean and its length must never exceed 6mm. Do not hesitate to refocus it after burning.
Always protect the surface on which the candle is placed.
Never let the candle burn until the wax is used up.
