Large Lava Rock
From our Lava Rock Collection, it measures on average 4″ – 6″ and is used as an accessory to our Fire Glass or fire pit. We recommend using Lava rock as a filler if you have a deep fireplace or firepit. For a complete design, add Fire Glass on top to cover the fire rock thoroughly so it will not be detectable. We currently offer lava rock in 10 lb. bags, which is equal size to 20 lbs. of Fire Glass.
PLEASE NOTE:The lava rock will vary in color from brown to black, this is normal.
Because lava rock is economical, it is the perfect choice as the first filler that goes into a very large and/or dept fire feature to cover up the gas piping and tubes. Once the lava rock is spread the way you want it, add a layer of fire glass to create a truly astonishing design that will instantly become the focal point of your home or yard.
