Soy Candles are sometimes made with a solid core in the candlewick, but in today’s market, the core of the wick can be made from zinc or tin. Recently I saw a post on another blog talking about lead in wicks. I felt it was necessary to post a response to that article, because lead in candlewicks was banned in the US Marketplace in 2003.
Candle manufacturers and their suppliers here in the United States are represented by the National Candle Association (NCA); a major trade association. Purchase your candle wicks from a reputable candle supplier.
Use of lead wicks was voluntarily discontinued during the mid-1970s, and they asked every US candle manufacturer to agree not to use lead wicks and sign a formal pledge to this effect along with all NCA members. However, if you have any doubt about the metal core containing your candle wick, get a white piece of paper and rub the wick on it. A lead core will leave a gray mark. If you have any doubt , dispose of it.
Just be careful when you’re purchasing inexpensive foreign imported candles, as not all countries apply the same quality standards, and you would still be wise to question cheap imported candle wicks.
Remember it is not just what is in the wick being burned, but what candle wax the candle is made from. Paraffin wax candles still give off 11 known carcinogens, so you can still be polluting the air in your hom, whether a lead wick is used or not.
