Medium Lava Rock

Bring the magnificence of volcanic rock to your home oasis with American Fire Glass medium, black lava rocks. Sourced in the USA & naturally occurring, these fire rocks are formed as volcanic magma rises to the surface, cools & releases gases which give the rocks their coarse, porous surface. Because of this formation lava rock can withstand the most extreme temperatures without sustaining any damage or crumbling, making them a cost-effective, long-lasting & beautiful addition to your fire pit, fire bowl & indoor or outdoor fireplace. Medium lava rocks may be used exclusively in a fireplace or fire pit, or as a base or filler for other fire media like fire glass, light stones, or fire beads. For deep set fire pit projects, fire rocks are a must-have because they are lighter weight by mass & also economical as the base filler to camouflage gas piping & tubes.

Lava rock offers durability and provides a low maintenance unique natural element that looks great as part of your indoor or outdoor decor. Additionally, American fire glass lava rocks are great in soil to retain moisture for plants & work well as an addition to aquariums & ponds. The exotic, classy look of the lava rocks adds a warm, tropical & rustic elegance to your fire feature, no matter where your home paradise is located.

Design & Construction Features:

American Fireglass sifts, sorts and packs all of our lava rock by hand. This way we can guarantee that they are top quality, can be used in a fire pit and have no left-over gas pockets that could burst. For optimal results, our recommendation is to pour a minimum of two inches of lava rock over the firepit burner, which allows the gas to filter evenly through the lava rock media. Remember to cover your fire pit when not in use and do not use the fire feature when wet.
