Know before you buy
These rocks are specifically designed for gas fire pits. They should not be used in wood-burning pits, as the intense, direct heat from wood fires can cause the rocks to crack or pop.
Coverage depends on the dimensions of your fire pit burner pan. A 20-pound bag typically covers about 0.5 to 0.75 cubic feet, which is usually enough for a standard-sized residential fire pit.
It is common for lava rock to have some loose dust or debris from shipping. It is recommended to rinse them with water and let them dry completely before placing them in your fire pit to prevent any soot or dust from blowing around.
Black lava rock is naturally heat-resistant and durable, so it will maintain its color well. However, over time, you may notice some minor soot buildup from the burner, which can be cleaned off if desired.
While you can technically mix them, it is generally not recommended. Lava rocks are much larger and heavier than fire glass, which can lead to uneven heat distribution or block the gas ports on your burner.
