ABSTRACT:
In order to produce vividly colored flames, instead of conventional primary combustion agents, such as paraffin and stearic acid, which produce a yellowish orange color by themselves, the primary combustion materials are used which form a colorless flame such as ethyl carbamate (urethane), dimethyl oxalate, and/or trioxane; in addition, an oxidation accelerator catalyst is absorbed on the cotton combustion wick, to result in a candle that itself burns with a strictly colorless flame. A coloring wick is separately fabricated containing a color-forming compound as well as oxidation accelerating catalyst and preferably may be coated with resin on its surface. The coloring wick is then placed adjacent the combustion wick, and a candle is formed using the aforementioned primary combustion material. One or several coloring wicks may be embedded parallel to the combustion wick or may be embedded coiled around the combustion wick.
