Legend has it that coil candles were developed in the 1600's. Americans had an abundance of beeswax which they twisted into rope candles. Called courting candles, parents could time how long a suitor spent with their daughter using the inventive, self-extinguishing candle. Pure beeswax coil candles are naturally pliable and will burn for approximately 20 minutes per inch. 40-hour refill candle.
