ABSTRACT:
The invention provides a system and a method for improving the delivery of volatiles from a burning candle by providing a stabilized laminar gas flow adjacent a volatile-containing molten pool, ensuring an enlarged molten pool by close regulation of thermal transfer between a monolithic candle mass and the surrounding atmosphere, and minimizing volatile loss through unregulated thermal gradients.
