Grand Canyon 6" Cannon Balls (CB6-4) make a bold, modern firebed for linear or traditional fireplaces. Formed from fiber-refractory material and sized at 6 inches in diameter, the spheres read like sculptural elements—clean and minimal with or without flame. Use them singly as accents or group them for a stacked installation, then finish the bed with lava granules or crushed reflective glass for depth and contrast.
Each 4-piece set is suitable for indoor or outdoor use and pairs well with Grand Canyon Glass Burners or H-Burners. Choose Black, Gray, or White to dial in the tone against your media and flame.
