Small Lava Rock
Small Lava Rock can be added to your fire pit as a filler under fire glass or fire beads. Determine the total amount of fire glass needed for your fire pit and divide the total by 2. Purchase half the total amount in small lava rock and half in fire glass or fire beads. Place the small lava rock in first and then cover with the fire glass media.
These cinders are guaranteed fire-safe. They give a natural look to complement your fire pit. Since these rocks are naturally formed, their size and shape varies.
