Is lava rock good for fire pits?
Some materials like hard rock, gravel, or sand weren’t meant to reach high temperatures and can spark and explode if your fire gets too hot.

Will lava rock explode in a fire pit?
Lava rocks are good for fire pits as they disperse the flames, spread the heat and look great when burning. They can withstand very high temperatures without cracking or exploding (if burnt from dry), and can also retain heat for several hours which makes them ideal for all types of fire pits.
Why are my lava rocks popping?
The lava rocks are popping because they have water trapped inside them. Water enters the porous rocks through the tiny holes, and when the rocks become hot, this water turns to steam. The pressure caused by the steam leads to the rocks exploding. If you hear a pop, don’t panic.

The best defense against weeds growing in lava rock is landscape fabric. The fabric allows air circulation and water penetration but blocks most types of weeds from sprouting without the need for chemical herbicides.
Are glass rocks or lava rocks better?
Both are good conductors of heat, but fire glass can generally produce and retain warmth more efficiently. However, lava rock prices are typically more budget-friendly.
How do you maintain lava rocks?
