The inside candle can be wax, paraffin, gel oil or polyamide-based and can be scented or unscented. The outside shell can be made of paraffin wax and a reinforcement having a melting point of at least 70° C. and is scented at a level so that fragrance is continuously released without burning and is further activated by lighting the core candle. The composite scented candle can be presented as a pillar candle.
