Can you put red lava rock in a fire pit?
Red lava rock is an inexpensive, aesthetically pleasing material to add color and efficiency to your gas-powered fire pit. Prefabricated or home-built fire pits designed for propane or natural gas can use lava rock for more even, effective heat.
How do you keep lava rocks from exploding?

How much lava rock do I need for my fire pit?
To calculate the amount of lava rock needed to fill a circular fire pit or bowl, use the following equation: Diameter X Diameter X Depth, divided by 24 = pounds of lava rock needed. We recommend a minimum 2” depth for most installations.
Does lava rock hold heat?
Lava rock is very porous and hardly holds heat at all. Stones are at the other end of the spectrum. They can hold and radiate heat long after the fire is extinguished.
Why are my lava rocks popping?
Lava rock is very porous and will absorb and retain water in all those little nooks and crannies indefinitely. Or until the heat of the gas flame turns that water to steam and the rocks explode and go flying. You say you ‘let them dry’.
Can I put lava rocks in my fireplace?
Lava Rocks can be easily placed in gas fireplaces. They are one of the best natural heat-retaining materials that create an ambience to any garden and living room. The stones have a unique look as they are formed from volcanic lava which makes them more durable than normal rocks.

What rocks will explode in a fire?
Porous and layered sedimentary rocks like limestone, sandstone, shale, and conglomerate, and breccia can explode when heated. Extrusive igneous rocks (pumice, basalt, rhyolite, andesite, dacite) and foliated metamorphic rocks (slate) can explode if they contain water inside. River rocks can also explode.
What does lava rock do for a fire pit?
Functionally, fire pit lava rock provides a semipermeable barrier that protects fire pit burner components from the elements, facilitates the even distribution of flame and the resulting heat, and shields the gas burner from direct exposure to the surface flame.
