These Extra Large Black Lava Rocks by American Fireglass can be utilized both indoors and outdoors: In fireplaces, fire pits, fire tables, and other fire features. They can withstand high temperatures in any fire feature because of the natural process magma goes through when cooling. As the magma nears the surface and cools, the rock releases gas bubbles, which form the coarse, rough surface of the lava rock.
All lava rocks from American Fireglass are sifted, sorted, and packed by hand. This way, they are top quality guaranteed, they can be used in a fire pit, and have no left-over gas pockets that could burst. For optimal results, we recommend pouring a minimum of two inches of lava rock over the fire pit burner, which allows the gas and flame to filter evenly through the lava rocks.
