1/2" Medium Black Lava Rock - 10lbs - By American Fireglass

Fire rock is a good way to fill a large amount of space in a firepit. Lava Rock can be used to fill under fireglass and as a substitute to sand in burner pans. We do not recomend using sand as a filler because it could retain water and cause damage to the burner system. Sold in 10 lb bags.
