Fire Pit Lava Rocks in 10 lb Bags
Lava rocks provide a rustic, earthy aesthetic, yet sits very well in both contemporary and traditional settings alike!
Naturally occurring, it is formed as volcanic magma rises to the surface, cools, and releases gases which gives these rocks their coarse surface. Because they are volcanic, they can withstand extremely high temperatures without sustaining any damage or crumbling.

American Fire Glass meticulously processes, sifts, sorts, and then hand-packs the 10 lb bags, ensuring the highest standards of quality. Look no further, we supply the best lava rock for gas fire pits.

Measure your fire pit burn area in accordance with the detailed instructions, and input the data into the calculator. The result will provide you with the quantity (lbs) required.
