Soot is a natural occurrence for any candle. If your candle is continuously releasing soot, it can be the result of carbon build-up on the wicks, not trimming the wicks of the candle, over-burning the candle, or burning the candle in an area that is receiving a draft from a vent. Tip: If you are experiencing excess sooting, try trimming your wicks to 1/8’’, moving your candle to another location, or extinguishing your candle if it has been burning for more than 3-4 hours.
