Small Black Lava Rock (1/4 In. – 1/2 In.) 10 Lbs. Bag
Lava Rocks can be used on their own as a focal point of your fire pit, or as a base layer underneath fire glass to keep the costs of your fire pit project down. The choice is yours! Lava Rock can withstand high temperatures in any fire feature because of the natural process magma goes through when cooling.
