How can one tell whether a candle has a lead-core wick?Updated 7 months ago
A consumer can determine if a candle has a lead-core wick by using this simple test: Rub a piece of paper on the tip of an unused metal wick. A lead-core wick will leave a gray pencil-like mark, while zinc or tin will not.
It is important for consumers to know that wicks made with cotton, paper, zinc, or non-metallic materials are safe.
