Black Lava Rock: 47 lb of 1" - 1 1/2" Black Lava Rock, 1 bag per 1 cubic foot

Woodbridge Black Lava Rock is a 47 lb bag of 1"-1-1/2" natural volcanic lava rock for use in outdoor fire pits and fire bowls.
Overview Woodbridge Black Lava Rock is a natural volcanic media that serves as fire glass or decorative fill inside gas fire pits, fire bowls, and fire tables. The 1"-1-1/2" stone size creates an open, airy bed that allows gas to flow freely through the media while providing a natural black stone aesthetic that complements modern and rustic outdoor fire installations. At 47 lbs per bag, one bag covers approximately 1 cubic foot of fire pit volume. Lava rock is lightweight relative to its volume and handles direct flame exposure without cracking or degrading. It disperses the gas flame across its surface for a campfire-like appearance in gas fire features.
