Made of 100% beeswax and 100% cotton wick, these taper candles are imperfectly simple. Many of the petroleum-based paraffin candles of today release soot, not to mention many other chemical by-products. Not only do beeswax candles not produce soot, they also release negative ions which help to purify the air. Beeswax candles are also known for having one of the highest melting points. Thus they burn much longer than your average candle.
