For a complete design, add Fire Glass on top to cover the fire rock thoroughly so it will not be detectable. 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.
American Fireglass sifts, sorts and packs all of our lava rock by hand. For optimal results, our recommendation is to pour a minimum of two inches of lava rock over the firepit burner, which allows the gas to filter evenly through the lava rock media. Remember to cover your firepit when not in use and do not use the fire feature when wet.
