Instantly transform any gas fireplace or fire pit with American Fire Glass Lava Rock adding an exotic, yet classy look to your fire feature. Because these rocks are naturally occurring, each unique piece varies in size from 1/4" to a whopping 6" thick size, depending on the size option chosen. Lava Rocks are formed from cooled volcanic magma that rises to the Earth's surface. Their coarse and textured profile is created from gas that is released which gives these rocks their unique, porous characteristic.

Because they are volcanic, they can withstand extreme temperatures without sustaining any damage or crumbling. They retain heat much better than their log counterparts, making them much more cost effective. Lava Rocks may be used exclusively in a gas fireplace or fire pit. However, they may alternatively be used as a base or filler for other ornaments, such as fire glass or Lite Stones. Whichever way they are used, the resulting effect is truly fascinating. The best part is that they require very little maintenance! So if you're looking to add a touch of nature to your living space, these lava rocks from American Fire Glass won't disappoint.
