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 coloured flames. For coloured flames a colourant wick delivers the colourant to the portion of the flame that maximises the temperature and the residence time of the colourant in the flame. The colora nt 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 colourant wick relaxes to lie in the hottest portion of the flame.
