Lava Rock - Multiple Size Options

Lava Rock is a natural fire pit media perfect for using as the first filler that goes into a large fire feature to cover up the gas piping and tubes. Lava rock is economical, one ten-pound bag of lava rock will fill as much area as twenty pounds of fire glass! You may use it alone, as a base for fire pit logs or stones, or add a layer of fire glass over top to create a beautiful modern focal piece. Because they are natural volcanic rock, they can withstand extreme temperatures without crumbling or exploding. Available in 4 rock sizes - 10 pounds per bag, you can stay consistent with multiple bags of the same rock size or mix it up with a few bags of each size for a unique look. Color ranges from black to brown.

    From the online picture, I thought I was getting larger rocks than pieces of rocks.
