  • Publication number: 20030134246
    Abstract: The wick of a candle is anchored above the bottom of the candle a flame extinguishing distance so that the wick is extinguished by the candle's molten solid fuel when the wick is consumed. Placement of the wick in this manner helps to eliminate bum through. Additionally, a bottom cavity may be formed in the candle. The cavity may be used for the purpose of helping to anchor the wick a desired flame extinguishing distance above the bottom surface of the candle. The cavity may be advantageously filled with scrap wax material since it will not be consumed by the burning wick.
