Abstract
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 constit…
