A fireworks artillery shell for use as a consumer firework which may be propelled by the use of a mortar is provided which includes a casing, a lift charge, an effects charge, a timing fuse and an ignition fuse, and seals. The seals are provided within the casing above and below the effects charge to increase the burst effect of the effects charge. The lift charge is positioned within the casing and below the lower seal, and upon ignition, lifts the fireworks artillery shell into the air. The seals promote a harder break and more explosive effect from the effects charge without interfering with the lifting charge.
