Red Lava Rock For Fire Pit

Distracts From Man Made Elements

Sun Joe 23″ Propane 50,000 BTU Fire Pit with Lava Rocks on QVC

Just like I dont like the flat look of most water features, I have an issue with patio furniture.

Patio furniture looks out of place in natural themed gardens. You can see and feel that they are man made. I personally prefer some short walls or flat stones for a natural and improvised lounge area.

But just so you see how versatile lava rock is, the only time I found patio furniture to not be out of place was when it was used in conjunction with a red lava rock gravel.

In a Spanish Arabian style rooftop garden in the Algarve. Its something weird, but I found that only Arab theme gardens and Zen gardens just integrate artificial fixtures better than other motifs. And the red gravel just unifies the setting so well that everything just looks like it belongs together. The warm reddish cityscape also works well to complement the rooftop garden. So in that scenario, even artificial man-made elements just get pulled into the theme.


The best way I can describe it is that it was just like flagstone paths. On their own, they look manufactured, but when integrated into a path with some red gravel, you believe it despite the bolder contrast.

The red gravel lava rock makes a bolder statement, especially when combined with a pale flagstone. Its like the light is seduced by the contrast and stops noticing the artificial feel of the individual element.

Vibrant Walls And Irresistible Waterfalls

Lava rocks, lava glass, fire glass and landscape glass make a bold statement, and this makes them ideal for large set pieces. For example, they can make any plain wall or non-horizontal surface vibrant and textured. The reason this works is that large 3D shapes are already shocking, so adding texture to it isnt all that surprising.

Add some running water over them, and you have an exquisite water feature that has a unique textured look. The water blurs the texture even more and integrates the glare in itself. Its a really great effect that adds vibrancy even to still water.


We are not very fond of the bland slat look of most water features. The clean ceramic look is too similar to a bathroom and should be separate from the garden. We feel the same about pairing stones around water features. Look at rivers and streams, the bottom is either dark and cold or rich and brown in the warmer areas.

Conversely, if you go to an oceanic theme, you are met with dark blues, or emerald tones, Nowhere on earth can water be found on an insipid flat white background outside of the human bathroom. Its unnatural, clinical and uninspired.

It is recommended to use smaller lava rocks on your first layer of rock. This will increase support by adding a solid foundation for the following layers of rock. This method also provides thermal protection.

When first opening the container of lava rocks, dump some lava rocks into a bucket and rinse them off to rinse off any dust it may have accumulated during shipping. After you have rinsed them, dump the rocks onto a towel and allow them to fully dry for a few hours.

You can add the lava rocks once the fire pit is properly put together, which includes:

  • The burner being in place

Place enough lava rocks around the fire pit and burner so it is just enough to cover the burner, being careful not to pile them on too thick. Now your fire pit is ready.


What Is Fire Glass Exactly

Fire glass is not regular glass. Regular glass can heat up and explode. These crystals are tempered or fire rated. Therefore, it does not burn or melt. It will not discolor either, which makes it a great option for both outdoor fire pits and indoor fireplace beds.

That said, Glaz Chips Fire Glass says that propane gas burns dirtier than natural gas. Therefore, a slight film of soot build-up can accumulate on the glass itself. They recommend rinsing down the glass after an extended period of time to clean them.

How Much Fire Glass Do You Need

According to The Magic of Fire, a fire pit with 1 depth and a 24 diameter needs approximately 24 lbs of glass. Alternatively, a square fire bowl measuring 24 x 24 will require a little more: 30 lbs.

If your pit has a deeper fire bowl and you want to save money, they suggest using lava rock as the bottom layer. Lava rock costs substantially less. This strategy lets you fill the space while taking advantage of the increased heat of the fire glass on the top layer.


If you only need a small amount of fire glass, Bond sells a 10-lb jar of Lava Glass in multiple colors . A jar sells for about $20 .

Alternatively, buying smaller container lets you mix and match bead colors without having to buy excess pieces. Of course, you can also use these lava glass rocks in a traditional indoor fireplace because they are heat resistant.

Are There Different Kinds Of Lava Rocks

There are several different kinds of lava rocks. In fact, you have quite a few options when it comes to size, color, and consistency. Most lava rocks are black, dark red, or gray in color.

You can also get them in large, medium, or small chunks. You can even find tumbled lava rocks, which are smoothed out to prevent the rough edges that they typically have.

What color you get is a matter of preference, but size is a different story. The smaller the lava rocks, the more evenly they will disperse heat. So if youre concerned with providing warmth with your fire pit, you may consider medium or small lava rocks or a mixture of both!

What Are The Chemical Components

There are a few main and subsidiary chemical components in lava rock. These components include the elements:

In fact, they contain a high amount of iron. Iron was discovered around 3500 BC and has a melting point of 2800 degrees Fahrenheit! This aids in the heat resistant property of lava rocks.

Magnesium was discovered in 1755. Its melting point is 1202 degrees Fahrenheit. This element is what helps enable lava rocks to be lit and also make them burn brighter!

Calcium was discovered in 1808. It has a melting point of 1548 degrees Fahrenheit.


Iron and Magnesium are known as the ferromagnesian group, which simply means they form essential chemical components. These ferromagnesian elements have a fast cooling rate.

Lava rocks also contain a minute amount of silicon and aluminum. Silicon was discovered in 1824 with a melting point of 2577 degrees Fahrenheit. Aluminum was discovered in 1825 and has a melting point of 1220.581 degrees Fahrenheit.

Dos And Donts For The Jungle

Thats the difference between something actually powerful and something that is different from the norm. Powerful assets outshine, sometimes literally everything else. The fear is that they become eyesores. But guess what, rectangular turf can also be an eyesore if used as an accent. That rich green can look really weird in an arid themed garden. But still, people do it. As a statement of disobedience towards nature: Look at me, I have water in the desert!

In my own personal opinion, even a glowing red lava rock plucked right out of a volcano isnt intense, its an earthy tone. It verges on the side of bland, and it defines what we perceive as natural color tones. Its literally the easiest tone to blend into other design elements and can serve as an accent, counterpoint to something brighter or background.

As we mentioned before, one of the main advantages of using lava rock is that its heat-resistant. This means that your fire will be able to burn hotter and longer without damaging the rocks.

When choosing the right type of media for your fire pit, you have to consider factors beyond aesthetics. You have to weigh the cost against their durability and lifespan as well as the type of climate youre in.

For example, while fire glass may be the more heat-efficient option, lava rocks can fare pretty well in more humid or hotter climates that only experience cool drafts every now and then.

But, if I had to choose one, I would definitely go with fire glass as theyre durable, long-term, and produce beautiful flickering hues that make chilly evenings a joy to welcome.

The most important thing to remember when deciding where to place your fire pit is ensuring it will be in a good, well-ventilated area. If you want to place a fire pit on your deck, please be careful.

There are mixed recommendations on whether or not fire pits should be placed indoors or on covered patios due to the potential hazard of not having enough ventilation.

Hazard Warning: A fire pit that is not well-ventilated will develop a buildup of toxic smoke and harmful gases, such as carbon monoxide!

You also need to learn of your local regulations regarding the set up of your fire pit. Some of these regulations include:

  • Fires should be a minimum of 25 feet away from buildings and combustible structures or materials, like decks or trees. Sometimes there is an exception for approved portable outdoor fire pits.
  • There may be a minimum clearance above the fire of 21 feet for overhead branches.
  • Typically, a fire pit cannot be placed within 10 feet of property lines.

In addition to the area you are placing your fire pit in, you will need to keep in mind what you are placing your fire pit on. Do not place your fire pit directly onto a wooden surface.
