Abstract: A clean and attractive carbonaceous fuel product is provided for improved convenience and marketability. Coal or charcoal can be coated with a clean and durable coating for cleanliness in handling; and, the coating can be colored as desired. Further, a metal salt can be added to the coating or the product itself to color the flame while the product burns. Paraffin can be used as the coating, and the paraffin is maintained above its melting point to improve gloss. Other additives can also improve gloss. Coal is preferably coated with latex to provide an attractive coating that will prevent breaking of the coal. A flammable liquid can be incorporated into charcoal briquettes for easier lighting; and, the liquid reduces the amount of paraffin used in the coating. A masking agent hides the odor of the flammable liquid, the masking agent being in the coating rather than in the flammable liquid itself.
