Lava Rock for Fire Pits
Lava Rock for Fire Pits
What is lava rock?
Lava Rock is formed as Volcanic rock or magma rises to the surface and begins to cool. During this process gas is released, creating its rough, porous surface.
Born of Volcanic activity, it is pretty well disposed to handle the comparatively low temperatures of a fire pit or fireplace.
It had been used as the finishing touch in fire features for many years. More recently, it has had to share the limelight with more colorful fire glass. However, it can still have an important and practical function even if it does not have the starring role in your fire feature.

Tumbled stone is lava rock that has undergone a process to smooth out the rough surface, creating a pebble-like finish. It still has the same porous qualities and such but is transformed, with a more contemporary aesthetic.
The Stones are too big to be used alone, without a filler to cover the burner which helps the gas spread safely, and evenly throughout the pan. Small-sized lava rock is perfect for this and as such is used in conjunction with not only the larger-sized stones or rock but also used as a filler base for Fire Logs or other fire ornaments.
Lava Rock can also be used by itself. In fact it can look pretty amazing! So much so that it is used in many different ways, for example lava rock used in landscaping can transform a backyard!

Lava Rock used as a Fire Pit Filler
Fire Glass is twice as dense, which means that a 10 lb bag will only fill half the area/space as a 10 lb bag of lava rock.
People are often surprised by how much fire glass they need and the cost soon adds up. The ‘Pro Tip” here is to use small-sized Lava Rocks as a filler underneath your fire glass. Generally, this reduces the quantity of fire glass you need by about half!
