Fire by Design Black Lava Rock is the perfect complement to your new Fire Feature if you are looking for a natural, rustic look. Nothing comes close to real Lava Rock, forged by fire deep inside the Earth! It also works great as a foundation for a layer of decorative Fire Glass.
Each bag contains 0.5 cubic feet of Lava Rocks, hand-selected to be between 1" and 3" in diameter, the perfect size to be used on Fire Pits, Fire Bowls and Fire Tables.
Please refer to your Fire Feature's Product Page to learn how much Lava Rock it holds.
