Should lava rocks be added to Firepits?

Lava rocks are becoming famous day by day. Yesterday only I visited one of my neighbors just to see the most talked-about item of the town- The lava firepit. The smokey aroma of the lava rocks made the whole evening romantic and I thought it would be perfect for a romantic night out.

Many of us use burning wood but now we got something unique to add as well – lava rocks. But should lava rocks be added to fire pits? Let’s find out.

What Are Lava Rocks Exactly?

Lava rocks are a type of volcanic rock that is formed when lava cools and hardens into a solid mass. The word “lava” comes from the Latin word for fire, as it was once molten lava that cooled and hardened into these rocks. Lava rock is a rock that has been created by the cooling of hot magma or lava. It may have originated in an eruption of a volcano, but it can also form naturally on Earth’s surface without any human involvement.

The term “lava” refers to the liquid state of lava before it solidifies; however, this does not mean that lava is always liquid. In fact, most lava flows are composed of small pieces of glassy material called obsidian. This glassy substance forms when lava becomes too viscous to flow freely.

What Are the Different Types of Lava Rocks?

There are three main types of lava: basalt, trachyte, and pumice. Basalt is a dark-colored rock with a rough texture. Trachyte is a light gray rock that is often found in large blocks and is very brittle. Pumice is a light brown rock that is soft and crumbly.

Basaltic lava flows are usually darker than other types of lava because they contain more iron oxide. They tend to be thicker and slower moving than other types of lava.

Trachytic lava flows are lighter in color than basaltic lava flows because they do not contain as much iron oxide. These flows are thinner and faster moving than basaltic lava.

Pumice is a lightweight, porous rock that is white or yellowish in color. It is softer than basaltic lava and trachytic lava.

Do Lava Rocks Hold Heat?

Yes. Lava rocks hold heat and will continue to release energy even after you remove them from your fireplace. If you place rocks directly over a fire pit, you will increase the temperature of the stones and help keep the area warm. You should never use rocks near a wood stove or gas logs because they could catch fire.

Can You Burn Wood with Lava Rocks?

You cannot burn wood with lava rocks. However, if you place lava rocks around your fire pit, you will create a radiant heat source that will make your fire pit warmer.

Lava rocks are not flammable. If you have a burning ember in the center of your fire pit and then add lava rocks to it, they will not catch on fire. This is because these rocks do not contain any combustible materials.

What Does Lava Rock Do For a Fire Pit?

Lava rocks absorb heat from the flames and radiate that heat back out through the stone. This creates a radiant heat source that warms up the space around the fire pit. As long as there is no direct flame contact between the rocks and the fire, they will not ignite.

The lava stones can be used for cooking or heating food in an outdoor kitchen. They are also great to use on hot days when you want to stay cool. The lava rocks can be placed directly over the coals of your grill or fire pit so they can retain their heat all day.

You can leave lava rocks in your fire pit indefinitely. The only time you need to change them is if they start to crack or break apart. When this happens, you will need to replace them with new ones. They will retain their heat for years and provide warmth for many years. These rocks are also very durable and can withstand heavy use.

As the heat from the fire radiates through the hot stones, you’ll get that wonderful campfire feeling when you sit around the fireplace. In addition to looking better than an open flame grill, using a gas fireplace pit will be safer for both you and your family.

How Do You Start a Fire Pit With Lava Rocks?

To start a fire pit using lava rocks, first build a fire in your fire pit. Once the fire has burned down to glowing embers, take some of the rocks and place them on top of the fire. Make sure that the rocks are not touching the embers. Leave the lava rocks in place until the fire burns out completely.

If you don’t have push-button ignition, you’ll need a long match. Once again, remove the stones from the tank and turn off the gas tap. You light it by striking the match against the side of the container until it ignites. Then you use the valve to regulate the flow of oxygen into the flame. Move the rocks so they cover the burner safely.

If you do not like the look of the lava rocks, you can cover them with dirt or sand. This will hide the rocks and give the appearance of being natural. Keep an eye on the fire pit so it does not get too hot. If the fire gets too hot, you may need to add more wood to the fire pit.

Make sure that there is enough airflow around the fire pit so that the smoke does not escape into your home.

There is no set amount of lava rocks needed for each fire pit. Each fire pit is different. Some require more rocks than others. The size of the fire pit will determine how many rocks you need. A larger fire pit requires more rocks to maintain the same level of heat.

How Long Do Lava Rocks Last in a Fire Pit?

Lava rocks should last for around two years before they start to show signs of wear. Keep using them in your fire pit until you notice them getting a little crumbly looking. At this point, you will need to purchase new lava rocks.

When purchasing these rocks, check the size of the bag. It should be large enough to fit several bags at once. Also, try to find lava rocks that are still smooth. Smooth lava rocks are easier to work with than those that are cracked or broken.

What Happens if Lava Rocks Get Wet?

Lava rocks are a common sight on the ocean floor. They can be found in many places around the world, including Hawaii and Iceland. The lava rock is formed when molten magma or lava flows into the water. As it cools, it turns into hard volcanic rock.

A lava flow has lots of small holes, just like a sponge. Water gets inside, and when it’s heated up, steam forms. This steam causes the rock to expand and, well, pop.

Water will quickly erode the surface of lava rocks. Water will cause the rock to lose its color and become grayish-white. In addition, water will dull the shine of these rocks. To keep your lava rocks looking good, always store them away from moisture. 

To avoid having water damage to your fire pit, protect it from the rain, and dry out any wet rocks before lighting the burners. To get rid of excess moisture from the skin, put the stove on low for at least 30 minutes, allowing the heat to evaporate any remaining water.

If you have a gas stove, make sure that it is not running when you are lighting the fire. If you have a wood-burning stove, make sure that there is no fuel or kindling inside the stove.

You will also want to avoid having any water near the fire pit. Make sure that you put the rocks away from any sources of water. 

What Are Alternatives to Using Lava Rocks?

There are other materials that you can use instead of lava rocks in your fire pits. These include:

• Charcoal briquettes

• Wood logs

• Small pieces of coal

These alternatives have similar properties to lava rocks. However, they are much less expensive.

Lava glass or fire glass can be used for your fireplace. Lava glass is a type of dark glass produced from volcanic environments. Glass made from fire is called “fireglass.” It makes an elegant and luxurious atmosphere.


Lava rocks can be a fun and innovative experiment to add to your firepit. Just remember to never leave your lava rocks unattended. Always place them somewhere safe where children cannot reach them. It can be a good touch for your romantic night out sitting under the stars near the firepit with the smokey smell of lava rocks. Be attentive and enjoy your night.
