GASPRO Large Lava Rocks for Fire Pit, 10lb, 2-3 inch, Grey

GASPRO Large Lava Rocks for Fire Pit, 10lb, 2-3 inch, Grey

• Fire-Resistant Natural Lava Rock - Built to handle high heat without cracking or crumbling. Made of 100% natural volcanic stone (not ceramic, not concrete) for gas fire pits, fire pit tables, propane fire bowls, and indoor gas fireplaces. Allow rocks to dry completely before first use - wet rock can crack from steam pressure.
• Large 2-3 Inch Size, 10 lb Bag - Bold, natural-looking pieces that hide burner pipes and igniter covers in fire pit tables. One 10 lb bag covers roughly 0.5-1 sq ft at a 2-inch layer; measure your fire pit's interior - most 24-28 inch fire pit tables need 3-5 bags. Layer 2-3 inches over your burner—no tools, no expert needed. Pairs with GASPRO fire glass for a custom layered look.
• Heat Retention & Even Radiation - The porous volcanic structure acts like a thermal battery, absorbing heat while burning and radiating warmth long after the flames die down. It also spreads gas evenly for a fuller, cleaner flame - ideal for cool patio evenings, gas grills, and propane fire pit tables.
• Multi-Use - Fire Pits, Aquariums, Gardens - Use as fire pit filler, a base layer under fire glass, gas grill stones, aquarium substrate that supports beneficial bacteria, or decorative landscaping rock. Natural gray tones blend with stone, concrete, and modern patio furniture.
• Low Maintenance, No Ash or Soot - No ash, soot, or smoke. Rinse with water and air-dry fully between uses—no scrubbing needed. Built to last through seasons of use; simply top up with a new bag whenever you want a fresh look. Backed by GASPRO quality and support.
• Important - Not for wood-burning fires—wood flames create extreme temperature swings that can crack stones and cause flying debris.
