Beeswax is a natural wax that is produced by female honeybees. These candles are highly prized and considered by some to be the most pure candles available. Pure beeswax will burn brighter than other types of candles. They burn cleaner than paraffin with less smoking and fewer drips. The best beeswax candle will be made with a cotton core wick. Cotton core wicks burn cleaner than those with a zinc core.
