ABSTRACT:
A graphic image is applied to a candle by depositing paper having a preprinted image atop a pool of molten wax for a few moments so that air is driven from the paper. The air-free paper is then positioned inside a candle mold and molten wax is poured into the mold. When the wax has cooled and the candle is removed from the mold, the paper is air bubble-free and is therefor transparent and not visible. The image is as clear as if it had been printed onto the candle. In a second embodiment, the image-bearing paper, after having been deposited atop a pool of molten wax for a few moments, is rolled into a cylindrical shape and placed concentrically into a candle mold having an interior diameter greater than the external diameter of the cylinder. Molten wax is then poured into the mold and the candle is removed when the wax has cooled. The result is the same as the first embodiment, but the image is covered by a layer of wax having a radial thickness equal to the difference between the external diameter of the cylinder and the internal diameter of the candle mold.
