What is lava rock:

- 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.
