Abstract: An artificial fireplace log containing pyrogenic coloring matter which produces colored flames upon ignition of the log continuously until the log is consumed. The log is composed of combustible materials, preferably sawdust and wax, and contains pyrogenic coloring matter distributed throughout the log mix. Additional pyrogenic coloring matter is adhered to the surface of the log, preferably along two adjacent longitudinal sides corresponding to the top and front of the log as it is positioned in a fireplace. The process of the invention includes the steps of preparing an artificial log mix containing pyrogenic coloring matter, molding an artificial log with the mix, and adhering pyrogenic coloring matter, preferably in the form of dry, finely-divided particles, along the surface of the log.
