Extremely versatile

Lava Rocks can be used on their own as a focal point of your fire pit, or as a base layer underneath fire glass to keep the costs of your fire pit project down. The choice is yours!

Can handle the heat

Lava Rock can withstand high temperatures in any fire feature because of the natural process magma goes through when cooling. As the magma cools, the rocks release gas bubbles that form a coarse, rough surface around the rock.

Other uses

Besides being used in the traditional sense inside a fire feature, we have seen a growing number of our customers using them in landscaping, gardening, & aquariums as well!
