Lava Walls

Lava Walls are naturally-generating background walls found in the Cavern layer at a depth where lava replaces water. These naturally occurring walls can be destroyed with a hammer, but will drop nothing. These walls also do not stop enemies from spawning and cannot be used for proper housing.

On the, these walls can be crafted from Hellstone where they can be used like other craftable walls.
