Lava Rock – 10 lb Bag
These lava rocks will instantly give an 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! See our article demonstrating how to use fire pit rocks.
Available in various sizes!
PLEASE NOTE: The lava rock will vary in color from brown to black, this is normal.
Because lava rock is economical, it is the perfect choice as the first filler that goes into your fire feature to cover up the gas piping and tubes. Once the lava rock is spread the way you want it, add a layer of fire glass to create a truly spectacular look that will instantly become the focal point of your home.
How Much Do I Need?
The rule of thumb here is that, lava rock gives you twice the volume per pound as fire glass. So if you fire pit requires 40 lbs of fire glass to fill it, it will only require 20 lbs of lava rock. This is why small lava rock is a great material to use as a filler under your fire glass or larger Lava Stones, and therefore is easier on the budget. These lava rocks are in units of 10 lbs.
