    Abstract: A candle that produces a pure, brilliant colorful flame. The candle incorporates a color-forming agent in its wick and not in the candle body. The localization of the color-forming agent in the wick combined with the formulation of the candle body allows for the production of a pure, colorful flame and for an extended shelf life of the candle. The candle contains primary combustion agent (87 to 100% by weight), higher fatty acid amide(0 to 12% by weight), and pigment(0 to 1% by weight). The wick includes pure cotton wick (45 to 98% by weight), color-forming agent (2 to 55% by weight).
