A burnable article such as a fire log or a barbecue briquette is formed of a top fire-igniting layer, a middle fire-catching layer, and a body layer. The fire-igniting layer has a composition, in weight percent, of from about 47 to about 67 percent carbonized wood, from about 22 to about 34 percent barium nitrate, from about 3 to about 11 percent sodium nitrate, from about 3 to about 11 percent starch, from about 0.25 to about 0.65 percent zeolite, and from about 0.25 to about 0.65 percent potassium alum, the total of the constituents of the fire-igniting layer being 100 percent. The fire-catching layer has a composition, in weight percent, of from about 57 to about 67 percent carbonized wood, from about 18 to about 28 percent barium nitrate, from about 3 to about 11 percent sodium nitrate, from about 4 to about 12 percent starch, from about 0.15 to about 0.35 percent zeolite, and from about 0.15 to about 0.35 percent potassium alum, the total of the constituents of the fire-catching layer being 100 percent. The body layer has a composition, in weight percent, of from about 81 to about 91 percent carbonized wood, and from about 9 to about 19 percent starch, the total of the constituents of the body layer being 100 percent. The relative amounts of the layers may be different in different articles. For example, the fire log contains a higher relative amount of the body layer than does the barbecue briquette.
