Raymond WhitneyLava rock is formed naturally as volcanic magma is raised up to the surface. It then cools and then releases gases. This gives the rock its rough appearance.
They’re naturally resistant to extreme temperatures, which makes them perfect for the gas-fire pits. We’ll talk about how to use lava rock to make fire pits!
Why use Lava Rocks?
They have a rustic look. natural lava rocks for flames are a very popular option and are also a great option in an indoor gas fireplace.
Sandstone rivers’ natural rocks, natural rocks, and gravel aren’t ideal as gas pits as they tend to break or explode when heated to a high temperature. The Lava Rock is a safer alternative and has numerous advantages.
Heat Retention
Lava rocks excel in this and spread heat evenly for long periods of time. This is extremely useful in gas fireplace pits, which provide constant heat all the time with no cold areas.
Weatherproofing
The lava rocks inside your pit (about three to four inches) will protect the burning element of your fire pit in any weather condition. Because lava rocks are water-resistant it helps in transferring water to the drainage system of your fire pit.
Protect the Burner
When you ignite the fire pit with gas it moves the gas through the cracks in the volcanic rock and keeps the flame burning at the top. The heat and flame are on top of your fire pit. The lava rock shields the burner from this extreme heat since it has great insulation properties. This allows the burner to perform better and prolongs its lifespan.
Long-Lasting
Because of its volcanic origins, lava rock is able to endure extremely high temperatures and not break or be damaged. It requires minimal maintenance and is very robust, which means it can be used over and over.

The majority of fire pits require between two to 4 inches of rock lava. Every fire pit is unique and will come with guidelines on the amount needed.
It’s an excellent idea to make small lava rocks as your first layer of rock in the fire pit made of gas. Fill the pit just beyond the burning element.
The fire rock pieces that are tightly bonded provide an excellent base for the next layer of either lava rock or fire glass for instance if you are able to afford it.
