Do I need to use lava rock with my fire pit log set?

  • These outdoor fire pit logs must be operated with a burner and volcanic ash. We recommend adding lava granules or lava coals from about 1 inch below the bottom of the burner to 1 or 2 inches above the top surface. This serves as diffuser to the flame and will increase the life of the fire pit log set. A direct flame from the burner will break the bonding that keeps the logs intact during normal use.

  • DO NOT use lava rock, actual river rock, or fire glass, as this type of media is too dense can possibly explode!

Why do I need to install my burner with the holes pointed downward when using a fire pit log set?

  • Installing the burner with the holes pointed downward allows for better flame dispersion and avoids any damage from rainwater. It will also preserve the look of your fire pit log set - a direct flame will discolor the logs over time. Additionally, disregarding manufacturer's recommendations can cause stress cracks in the product and will void the warranty.


Lava rocks for fire pits are a great option to help enhance the ignition efficiency of your gas burning outdoor feature. Not only do they exude a rustic and natural look, they also provide a layer of protection between the burner and the flame. Because lava rock is lightweight and porous, it allows natural gas or heavier propane to flow through and around each piece. The gas dispersion creates a more natural looking flame. Additionally, the high heat from the gas fire is far less likely to discolor your burner thanks to this incredible fire media!

So what exactly is lava rock? Is it really derived from volcanic stone? The answer is yes! Lava rock is formed from magma as it escapes and flows from a volcano. As lava cools and hardens, gas pockets are created in the surface. The resulting harvest is lightweight, porous rock! Lava rock is different from sedimentary stones such as shale, which has been formed by pressure squeezing it together over millions of years. The composition of lava rock makes it is more heat and fire resistant than materials like shale and river rock, which can expand, crack, and explode when under the duress of high temperatures. 

We carry an extensive line of this fire pit media for all kinds of outdoor fire features:

  • Lava rock

  • Lava rock granules

  • Lava coals

  • Volcanic lava stone

Check out some of the uses and features of our lava rock:

  • Lava rock is much more affordable than decorative fire media. Many of our customers acquire lava rock as a "filler" for the bottom of fire pits, bowls, and burner pans. Then, they top off their feature with a thin layer (approximately 2 inches) of fire glass, lava rock granules, volcanic stones, or lava fyre coals. Not only does this method promote better gas dispersion, but it also means our customers can generate a savings and still achieve a look that has depth and dimension.

  • When used in fire bowls, lava rock creates a buffer between the burner and the sides of the bowl. This keeps the fire bowl cool to the touch, even with a heavy flame. Maintaining temperature is important as certain materials may crack if exposed to hot spots.

  • Many people enjoy the look of lava rock because of its raw, earthy appeal. The uneven shapes coupled with the air pockets found throughout the surface of the rocks help the flames burn in a more natural pattern.

  • The surface pores also make lava rock a commodity in contained gardens! They promote the incorporation of air, water, and nutrients into the soil. Lava rock is a popular mulch because, unlike wood chips, it will never rot. (Please note: because it is porous, lava rock is buoyant. If it is not contained and subjected to large amounts of rainfall or water, it will float away.)

It can be tricky to figure out how much lava rock is safe to use in your fire pit or fire bowl. For help with this matter, start a live chat with one of our friendly customer service reps! 


Are lava rocks made from actual lava?

  • Yes. Lava creates many different types of rock forms as it cools but most 'lava rock' products are basalts. They form when air pockets are trapped inside the lava as it rises to the Earth's surface, cooling and expanding. So it is very much like a stone sponge with its porous quality and light weight. And since the lava rock is literally hardened molten fire, it can easily withstand the heat of your fire feature without breaking a sweat. 

  • Because of its porous properties, we urge caution to avoid using your fire features if the lava rock it wet. The water trapped in the air pockets will expand as the lava rocks heat up, increasing the risk of the rocks cracking and even exploding from the pressure. 

What is the difference between lava rock and volcanic lava stone?

  • Lava rock and volcanic stone are derived from the same source: rapidly cooled lava flow. However, there is a difference between the two. Volcanic stone is also known as "basalt" and it forms from the most rapidly cooling lava. In fact, the cooling process happens so fast that the molten lava doesn't have time to form larger mineral crystals. The result is a grey to dark grey or black colored stone that has a fine grained mineral texture. It tends to be quite hard and extremely durable. Because it does have somewhat of a porous surface, it is totally safe for use in your fire feature.


Create a shimmering "fire and ice" display with our American-made fire glass! This is a stunning alternative to traditional log sets in your fire feature. The cut and texture of each individual tempered fire pit glass piece directs the natural fluidity of the flame as it graces the prisms below. Your fire feature will go beyond the definition of beauty when you embellish it with your choice of colored glass.

We have a vast collection of 1/4 to 1/2 inch fire glass colors, available in packages by weight and in your choice of 10 colors. You'll find a rainbow of solid colors as well as the attractive Sunshine Mix, featuring a variation of red, amber, yellow and orange tempered glass. Our reflective blue fire glass is certainly unique in nature. A layer of reflective material is embedded into each piece of fire glass, appearing transparent from certain angles and much shinier when viewed straight on!

When you add fire glass jewelry to your approved outdoor feature, enjoy these benefits:

  • Outdoor approved and non-toxic! 

  • Does not produce soot, smoke, ash, or fumes of any kind.

  • Tumbled, tempered fire glass can withstand temperatures up to 1300° degrees!

  • Allows gas from the burner to flow effortlessly through your fire feature, without impeding the look and quality of the flames.

  • Colors can be mixed and matched to liven up your feature.

  • Enjoy the glittering display, even during daylight hours!

It can be tricky to figure out how much fire glass is appropriate for use in your fire pit or fire bowl. For help with this matter, check out our handy glass calculator below! 

  • PLEASE NOTE: Unless otherwise stated, fire glass can be used with natural gas burning features ONLY & colors may differ slightly than what is shown online. Because propane is heavier than natural gas, it will sink to the bottom of your feature. Small pieces of fire glass will not allow propane to circulate, and this could can lead to explosion of this particular media. Even with larger fire glass pieces, there is still not enough room for the gas to dissipate from wind and other factors. Lava rock allows propane to dissipate and is the safest choice for your gas feature. (In addition, it is always a good idea to incorporate lava rock into the bottom portion of natural gas burning features.) Fireplace Doors Online is adamant about this for the safety of our valued customers. Some manufacturers offer specialty components (such as ventilation collars) that make the combination of propane and fire glass compatible. However, this is only offered with limited products.
