What Kind of Rocks Can Be Used in A Fire Pit?

When searching for good rocks for fire pits, one of the first things that you’ll need to do is to identify which kinds of rocks you can use for the said fire feature.

If you still remember your geology classes, you might have an idea that you can’t put all kinds of rocks on your fire pit. Some cannot take handle exposure to high temperatures and might crack and break as a result.

So if you want to know the best filler options for your fire pit, you first need to know which rocks are suitable for fire pit use.

Here are the most popular options that you can opt for:

Lava/Volcanic rock

Lava or volcanic rocks are possibly the most popularly used filler materials for fire pits because they’re definitely tolerant of very high heat.

These lava rocks for gas fireplace are formed from the lava erupted from a volcano, hence the name. This also explains why they can handle exposure to very high temperatures.

There are quite a few reasons why they’re top picks as fire pit rocks. Aside from being able to handle high temperatures, they’re very affordable. They certainly do not cost a lot so they’re very budget-friendly filler options.

They’re also good for drainage. So even if you live somewhere that gets a good amount of rainfall, you don’t have to worry about these rocks trapping the water inside your fire pit.

As a result, you can still easily light up your fire pit when you need to.

Lava rocks for gas fireplace also come in a few different colors. This makes them quite decorative as well. However, they don’t look too different from logs and embers so your fire pit will still have that classic appeal.

Fire glass

If you want something flashier, then you should check out fire glasses. As their name suggests, these fire pit fillers are made from glass so they have a nice reflective quality to them.

It gives off a magical and ethereal effect to fire pits, making them fancier alternatives to lava rocks.

The fun thing about fire glasses is that you have so many options to choose from. You can take a pick among the different makes, shapes, sizes, and colors available.

You can go for crushed glass or beads, for starters. You have so many color and finish options. There are also different sizes to choose from as well as material options.

When it comes to choosing colors, it’s up to your decor’s theme and color scheme. As for the size, it’s better to stick with larger options as they tend to make flames appear bigger.

You can, however, layer it with smaller glasses on top to add variety and movement to your fire pit.

River rock

While river rocks are also largely used as fire pit rocks, we don’t always recommend it. They tend to absorb a good amount of moisture so they can take a while to dry out.

This means that they won’t be easy to light up and may even pose risks to your home when lit on fire.

Do Rocks Explode in a Fire?

Since we’re already on the topic of fire pit rock dangers, it must be said that rocks can explode in a fire. As mentioned above, there are certain types of rocks that can explode in a fire.

River rocks are at the top of this list because they tend to absorb a lot of moisture.

However, just about any type of rock can explode when it’s lit up while still wet. The heat can cause the moisture trapped inside to boil and expand, creating pressure inside the rock.

It can then break the rock which can cause it to shoot out of your fire pit. This can hurt anyone standing near the fire pit, so it has to be avoided at all costs.

To avoid any accidents, it’s best to make sure to dry out the rocks inside your fire pit when it got rained on before you light it up again.

Buying Guide – How to Choose the Best Rocks for Fire Pit?

Now that we have discussed the finer points of the best fire pit rocks, the only thing left to talk about is how to actually choose one.

So for that, here are four of our top tips to help you make a good choice:

1. Choose between fire glass or rocks.

The very first thing that you need to decide on when buying fire pit rocks is to choose whether to get fire glasses or rocks. Each type has its own charm, so you have to carefully weigh your options.

Rocks are easy options, especially since lots of commercial fire pits include a bag of them for free. You can just opt to get additional rocks to fill your pit.

You might not even have to think about which color to get if you’ll only need to match the ones you got for free.

If you want fire glasses, you should be prepared to think things through. For one, you need to choose whether to get shards or beads. Beads are easier to handle but they don’t have the raw appeal shards have.

You’ll also need to choose from the various colors available to you. This can be quite challenging as there are so many options available.

Then, you should pick out the finish you want as they come in unpolished, regular, semi-reflective, and reflective varieties.

You should have a clear vision of how you want your fire pit to look like when making this choice. To make things easier for you, though, there are sellers that offer samplers so you can test out different looks for your fire pit first.

2. Be very particular about the pack’s quality.

Aside from the appearance, you should also be very particular about the quality of the fire pit rocks you’re getting. These items are meant to last a long while, so you have to make sure that they’re of excellent make.

To determine the quality of the item you’re eyeing, read reviews. If you’re planning on getting fire glasses, stay away from the ones that turn black and emit toxic fumes.

If you’re going for lava rocks, look out for the ones that are extremely dusty and brittle. Again, these items should last a while, so they have to be well-made in order to do a good job.

3. Set a budget.

Fire pit rocks come with a very wide price range. So to make the process simpler for you, you might also want to set a budget. Doing so will help you narrow down your options and help you make a choice with more ease.

4. Consider eco-friendly options.

Fire glasses and rocks are already ec0-friendly since they help build more heat without using too much fuel but there are still greener options out there.

For fire glasses, you can find some that are made from recycled materials so you might also want to check those out.

Final Verdict

If you’ll think about it, getting the best fire pit rocks is both a challenging and easy task. It’s challenging because you have to wade through a lot of options in order to find your perfect match.

It’s easy because you have lots of options and if you know what you’re looking for, there’s no reason to be daunted by the chore.

With the help of this guide, we’re confident that your search for the right fire pit fillers will be made easier.
