Can firepit rocks explode? Yes, it is possible. Especially if they are placed in the fire for a long time. The gas from the heated rocks could expand and make an explosion. It is not recommended to use fire pit rocks as decoration because of this reason. However, there’s no need to worry as long as you follow certain tips!
How to safely use fire pit rocks!!
First of all, it’s important to decide how you’re going to heat the rocks. It could be gas or wood. If you choose wood, please make sure that you put them in a metal basket first on the inside of the fire ring and then place the rocks on it after they are heated. This way, you can prevent the rocks from exploding since they will not be directly exposed to flame.
If you use gas, please avoid putting them in direct contact with the heat source (if it’s a propane fire pit). If possible, place the rocks on top of them instead of setting them on direct flames.
Also, make sure that you don’t let the rocks in the fire for a very long time. It’s not safe to keep them in hot flames. Keep an eye on the rocks and remove them from the fire once they start giving off crackling noise or explode while heating up.
Even if you follow all these tips, there’s still a chance that some of the rocks will explode. If you find any exploding rock, remove it from the fire right away before it causes injury or property damage.
Remember that fire pit rocks are not meant to be used as decoration and they must never be placed in the fire without being heated up first! Putting cold rocks in hot flames is just asking for them to explode. If you still want to use rocks in decoration around your fire pit, consider using lava rock or something similar.
What Kind Of Rocks Explode In Fire?
The most common rocks that explode in the fire are made of calcium carbonate. Rocks like limestone, marble, travertine, and chalk are common examples.
However, there is no exhaustive list of rock types that explode while heating up so basically, any type might be dangerous if left in the heat for too long. That’s why it is important to consider the material of the fire pit rocks you want to use and choose some other rocks or decorations that are safe for your fire ring instead.
Fill Your Pit With The Right Materials
Not all rocks can be used in a fire pit. For example, sandstone and soapstone will burn because they are made from sedimentary rock which contains silica, silicates, and other minerals that react with heat. The same applies to granite as it is also a type of igneous rock.
Other types of igneous stones like andesite, basalt, and pumice may not burn but they might explode due to the expanding gas. Lava rock can even cause burns so it is best to avoid using them in a fire pit.
Of course, rocks that contain metals like copper or iron ore will react with heat and create sparks that could injure you. This also applies to stones that contain other materials like fossils.
Fire pits should never be filled with sandstone, river pebbles, natural rocks, or gravel since they are more likely to fracture or erupt when exposed to high heat.
Finally, other types of rocks such as limestone or marble will react with heat and produce flammable gas which can expand and make them explode.
Distance Your Fire Pit From Possible Dangers
It is important to keep your fire pit away from trees, buildings, and other items that could be damaged in case rocks explode. The best distance will depend on the type of rocks and how powerful they are but usually, you should keep it at least 10 feet away from everything.

It is important to keep your fire pit away from trees, buildings, and other items that could be damaged in case rocks explode. The best distance will depend on the type of rocks and how powerful they are but usually, you should keep it at least 10 feet away from everything.
Also, make sure that there is nothing flammable nearby or put it away if possible. If you put flammable materials too close to the fire, they might explode and cause injury or property damage.
The safest choice is to put your fire pit in a location that is free of flammable material and far from possible dangers. Also, make sure to light the pit only after checking for any possible danger (like flying sparks).
What To Do If The Rocks Explode?
If you find any exploding rock, remove it from the fire right away before it causes injury or property damage.
Remember that fire pit rocks are not meant to be used as decoration and they must never be placed in the fire without being heated up first! Putting cold rocks in hot flames is just asking for them to explode. If you still want to use rocks in decoration around your fire pit, consider using lava rock or something similar.
You can put out the fire if you can do it safely but make sure to cover it with sand immediately after to prevent any embers from igniting nearby materials.
If there are hot rocks close by, move them away before they explode and cause injury.
Safe Rocks For Fire Pits?
You can safely leave in a fire pit rocks that are meant for this purpose. This includes pea gravel, lava rock, river rocks, etc.
Does Sandstone Burn?
No, sandstone does not burn because it is made up of mostly quartz which doesn’t react with heat or flame. However, it might explode if left in the heat for too long.
Can You Put A Fire Pit On The Grass?
No, you should not put a fire pit on the grass. This is because the heat might cause them to catch fire. Also, putting a fire pit on grass will create lots of smoke and might damage the grass and plants and in some cases, even cause fires.
You can either put it on a Fire Pit Mat or other fireproof material (e.g. bricks or cement).
A fire pit mat that protects your grass may be a wonderful addition to your yard. Even the most elegant deck might be damaged by heat if you don’t safeguard it, so having a mat that’s particularly made for your fire pit can be an excellent answer to the problem.
Furthermore, determine the size and appearance of the fire pit cover you’re buying. It should fit your fire pit perfectly and complement the design you desire.
Conclusion
Although fire pit rocks are safe to use as long as they are the right type, the best rule of thumb is never to put cold rocks in hot flames. If you can’t immediately use them, wait for them to warm up.
Never leave your fire pit unattended and make sure to keep it far from possible dangers (such as flammable materials) and away from your house, deck, trees, etc. That way you can make sure to avoid injury or property damage.
