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.
What do you put at the bottom of a fire pit?
What do you put in the bottom of a fire pit? You’ll want to start with a layer of sand at the bottom of the pit, and then top the sand with gravel, lava rocks, fire pit glass, paving stones or even bricks for your fire pit. Alternatively, you can simply use dirt.

If you do not have access to fieldstone, many garden and landscape design centers sell rocks that are perfectly suited for lining the perimeter of a fire pit.
What is better than lava rocks?
Fire glass is also able to distribute the heat of the flame more evenly due to there being more and smaller pieces of it compared to lava rock.
Is it safe to roast marshmallows over lava rocks?
Just don’t. The world’s leading experts on all things volcanic have warned people not to try roasting marshmallows over lava. Responding to query from an intrepid Twitter user, the United States Geological Survey pleaded with people not to venture anywhere near molten rock in search of the perfect toasted treat.
Why did my fire pit explode?
Concrete blocks, pea gravel, river rocks and other materials that are often used in DIY fire pits can trap water inside. When they are heated up, this can cause an explosion. Here’s a demonstration of what can happen when the building materials hold a little too much water and pressure builds up inside.
Can you use river rocks in a fire pit?
Rocks can explode in a campfire because of rapid expansion due to trapped water inside the rock, or through uneven heating. Although virtually all rocks have some amount of water inside them, porous and more permeable rocks have more water and are thus more dangerous inside a fire.

Why are my lava rocks exploding?
Lava rocks are very porous like a sponge. Water can get trapped inside of lava rocks when they get wet. When the wet lava rocks get heated up by the fire, the water inside turns to steam and expands. This creates pressure inside of the lava rocks which can cause them to explode open.
How do I get more heat from my fire pit?
