Volcanoes can erupt, but this cooled-off lava never will! These extra-small pieces of rock are lightweight, porous, and completely fireproof, making them an ideal decoration for fire pits, fire pans, and fireplaces. Being so small, they make a great ash-like decorative touch to gas fireplaces with ceramic fire logs. Pack them around a fire pit's burner, then cover with fire glass -- you'll get a great insulator between the fire and the fire pit's material and a pack-in tight enough to keep fire pit glass from falling through. Benefits and features: 1/4" Lava Rock can be used as ...
This a set of extra-large lava stones for use as a media in gas-powered fire pit and fire table burners. This is a 12 lb bag. Don’t cover the burner system with any additional shielding, grates, or other materials that have not been approved with YOUR fire pit/fire table assembly. Don’t add additional burner media or any other material not specified in YOUR installation and operating manual of your fire pit/fire table. Don’t allow burner media on pilot assembly screen.
Generally speaking, volcanoes are bad (you could ask the people in Pompeii, if they were still around to argue the point). But as it turns out, they're not all bad -- they give us lava rock! The flow of lava as it travels fills it up with micro-pockets of gas that gives the cooled rock a unique texture among stones. It's porous makeup allows it to be a near-perfect natural insulator from heat, and a great breathable coating for soil for landscaping. This lava rock has been sifted so that every granule is roughly 1/2" in diameter, allowing it to pack a little tighter than larger types ...
Lava rock looks great in as a garden mulch and is virtually fireproof, but don't ever try walking on it barefoot -- it's sharp and coarse! These Beach Lava Rocks have been rolled to completely wear down all of the sharp edges so that they appear to be stones smoothed in a river or the ocean. Make no mistake though, this is still the same lightweight and porous stone that insulates against fire and floats on water! It works great when coupled with sand burners and gas fire pits that want to have a beach-like decor, or as a supplement to fireplaces that use lighter shades of fire glass. Benefits ...
Want to make an impression with your fire? Sure, there are lots of fire pits that use fire glass and artificial log sets, and there are many more that use lava rock coals. However, these large Volcanic Fyre Stones™ from American Fyre Designs® look more like large sedimentary rocks while retaining the safety that you've come to expect from lava rock. These pieces are great in fire pits and fireplaces, but also good as a landscape supplement, giving your soil the aeration of lava rock with the look of heftier stone. Benefits and features: Looks good on top, but can be used as a filler ...

Where does lava rock come from?

Lava rock is volcanic stone; that is to say, it is chunks of rock that has been harvested from the lava of a volcano. Don't worry -- it's usually from inactive volcanoes.

Is it just stone?

Not quite. Unlike sedimentary stone (like shale) which has been formed by pressure squeezing it together over millions of years, lava cools quickly and so lava rock has many gas pockets in its surface making it lightweight and porous. Because it is formed from super-hot magma it is also more fire-resistant than other forms of stone that can expand, crack, and explode when put in a fire.

What is lava rock good for?

Because of its heat resistance, uneven surface, and low cost lava rock is a common component of gas fire features. There are several reasons for this:

  • As our most affordable fire media, lava rock is often used as a "filler." Many contractors use lava rock to fill up the bottom area of a fire pit, burner pan, or fire bowl so that they don't have to use as much of more expensive fire pit media like fire glass. 
  • When used in fire bowls, lava rock creates a buffer between the burner and the sides of the bowl.  This keeps the bowl cool to the touch even with a heavy flame. This is important, because some materials (such as concrete) may crack if exposed to hot spots.
  • Many people enjoy the look of our lava rock as-is. It gives a raw, earthy feel to any fire feature, and the uneven shape coupled with the microscopic pockets in the surface make gas flames burn in a more chaotic natural pattern.
  • The surface pores also makes lava rock a commodity in gardening, as they allow air, water, and nutrients into the soil. Lava rock is popular as a mulch and in garden pathways because unlike wood chips, it will never rot.

Can I use it in my pond or fountain?

Well... you could, I suppose, but there is one thing about lava rock that you need to know:

Lava rock floats in water.

The microscopic air pockets that I mentioned before can trap air inside, so despite its strength lava rock is lightweight and buoyant; most pieces float. If not retained properly in a garden, it can wash away quite easily -- make sure to put it in an area with good drainage so that you won't have to constantly replenish it.

Hello, I got your glass today and installed it.  I was impressed in how easy it was to put the plugs in that hold the glass in place – nice engineering there. I bought the wrong color – see the attached picture (the new pane is 2nd from left) – it should be lighter.  I’ll replace it sometime before I move out; in the mean time it’s a warning to not leave the fire unattended. Thanks for the great packaging, too – I can use that cardboard in projects so it’s going to be reused.

Fire pit has small flame
When I put my fire pit glass on top of the orafice, it seems like the glass is covering the hole/ports and the fire is very sporadic which is limiting the heat from the pit. Any suggestions on what I can do?
