Abstract:
A method of making a multilayered compression candle in which no two immediately adjacent layers contain the same colorant, which process comprises the steps of:a. Preparing x+1, where x is a whole number equal to or greater than 1, solid-fuel prill or powder layer mixtures, each layer mixture containing particles of a compatible solid fuel having a particle size of from about 500 to about 2000 microns, each layer mixture containing one or more colorants, and optionally, a volatile active ingredient from the group consisting of fragrances, insect control agents, sanitization agents and deodorants; b. Adding the x+1 layer mixtures of step a to a candle mold in a sequential manner so that no two immediately adjacent layer mixtures within the mold have the same colorant, each layer mixture being added in a quantity to produce a layer of a desired thickness; c. Subjecting such layer mixtures in the mold to a compressive force to form a candle shape within the mold, said candle shape having a substantially horizontal top surface, a substantially horizontal bottom surface, and one or more vertical surfaces communicating with said top and bottom surfaces defining the candle shape, said candle shape having x+1 substantially horizontal layers, each layer having a desired vertical thickness; d. Forming either during step â€œcâ€  or thereafter one or more axially disposed vertical wick cavities within such candle shape; e. Placing a combustible wick within each such axially disposed vertical wick cavity; such wick being placed to extend a flame sustaining distance above the substantially horizontal top of such candle to at or near the horizontal bottom layer of such candle shape; and then, f. Recovering a multilayer compression candle.
