Abstract: Modified charcoal briquets having a pillow silhouette when viewed from at least one side and configured to have less volume than similar unmodified pillow shaped briquets having the same dimensions are described. A random packing density for the modified briquets is between about 0.70 times and 0.92 times a random packing density for the unmodified pillow shape briquets. The random packing density for the modified briquets is between about 35% and 46%.

Abstract: A generally pillow-shaped charcoal briquet having a convex upper surface and a convex lower surface, wherein at least one of these surfaces contain an enhanced surface feature comprising one or more grooves. When two or more grooves are located on one or both convex surfaces, the grooves are generally parallel to each other and to two opposing sides of the briquet, and generally perpendicular to two opposing sides of the briquet. The briquets have improved ignition characteristics and enhanced burn phase properties.
