Abstract
A process for adding objects to a candle. Methods are disclosed for adding an object before the fuel has assumed its final state and after the fuel has assumed its final state. Several related approaches for introducing the object are disclosed, including making an incision to insert the object, retracting the fuel away from its container in order to slip the object in between the fuel and the container, and creating a melted region in the fuel which will allow the object's insertion. Once the object is in place, the fuel is locally heated above its melting temperature in order to reflow the fuel around the object. The candle is then cooled so that the fuel transitions back into its normal state.
