1/4"-1/2" #10 Small Black Lava Rock

These lava rocks will instantly give any old fireplace an exotic, yet classy look. Naturally occurring, these lava rocks are formed as volcanic magma rises to the surface, cools and releases gases which gives these rocks their coarse surface. Because they are volcanic, they can withstand extremely high temperatures without sustaining any damage or crumbling. Lava rocks may be used exclusively in a fireplace or fire pit, or may 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!
