US Patent 6921260 Candles with colored flames

A candle with transparent flame and flame temperature higher than paraffin candles consists of a fuel mix consisting of sorbitol, ethane diol and glycerol with a polyaramid wick. The candle can be used in catering and for the production of colored flames. For colored flames a colorant wick delivers the colorant to the portion of the flame that maximises the temperature and the residence time of the colorant in the flame. The colorant wick may be spirally wound around a former, heat set and then threaded with the combustion wick so that when alight the free end of the colorant wick relaxes to lie in the hottest portion of the flame.
