Ebonstone Brick

Ebonstone Brick is a building block. Unlike their raw block counterpart, they do not spread Corruption, nor do they spawn Eaters of Souls when present in high amounts, thus making them a safe construction material.

They can be used to make NPC houses and prevent enemies from spawning.

Unlike its Crimson counterpart, Flesh Block, (until 1.3.6) you cannot make furniture from Ebonstone Bricks.
