Black Lava Rocks Medium

You can use fire glass or fire stones in your fireplace alone, but for deep set fire pits it is best to lay down a lava rock base. Not only is it lighter weight by mass (ten-pound bag of lava rock will fill as much area as twenty pounds of fire glass) but is more cost effective for your fire pit project. This material can be utilized inside and out and can withstand high temperatures in any fire feature because of the natural process magma goes through when cooling. As the magma nears the surface and cools, the rock releases gas bubbles that forms the coarse rough surface in the lava rock. These medium sized rocks are 1/2 an inch to 1 inch in sizes and vary in color from brown to black, this is normal. Whether lava rock is your base covering or you choose to use only it in your fire feature, you are purchasing a material that is durable and long-lasting.
