American Fire Products Small Black Lava Rock 40 Pounds - LAVA-S-40
Our 40 lb bundle of Small Black Lava Rock includes four 10 lb bags—perfect for larger fire features or multi-zone installations. Sifted and sorted to ⅛" to ½" in size, these natural volcanic stones provide excellent heat distribution, improved airflow, and a rugged, timeless aesthetic.
Use them as a base beneath fire glass or showcase them on their own for a natural, rustic look. Whether you're building a backyard centerpiece or refreshing multiple burners, this bulk pack offers long-lasting coverage and clean, even-burning performance.
Designed for Coverage and Efficiency
With deep brown and black tones, our lava rock creates striking flame contrast while helping shield burner components from debris. The porous structure allows gas to filter evenly and promotes a consistent flame pattern. Each piece is lightweight, heat-rated, and made to withstand even the most intense temperatures without melting or cracking.
Clean, Safe, and Made in the USA
Like all of our fire media, these lava rocks are responsibly sourced, hand-processed, and packaged in the USA. They burn clean—no soot, no ash—and require little upkeep. Simply layer at least two inches above your burner and cover your fire pit when not in use.
Need a natural, high-volume fire media that performs as beautifully as it looks? Our Small Lava Rock 40 lb Bag offers commercial-grade results with long-term reliability.
