Aloha Bay T here is concern over black soot deposition and indoor candle air pollution. The U.S. Consumer Product Safety Commission met with the National Candle Association to discourage the use of lead-cored wicks. To our knowledge, very few American manufacturers ever used lead wicks, although some, until recently, used zinc core wicks. Black soot can be a problem, especially with candles made of inferior waxes and fragrances.
All candles emit soot.
The waxes and fragrances used should burn up entirely and evenly. The wick should be carefully calibrated for each type of candle. We have never used lead or zinc in any of our wick materials. Most of our wicks have a tiny paper core, which prevents the wick from collapsing into the liquid wax. Each wick is designed for our specific was blend, fragrance concentrations, and jar size.
