Blackstone Slab block in Minecraft
The Blackstone Slab is the dark stone of the Nether cut into a slab. Its material is Blackstone, so it keeps that block's look and toughness. All slabs, stairs and walls work alike, as the Stone Slab, Stone Stairs and Cobblestone Wall pages explain; the Blackstone page covers the material.
It is made with the Crafting Table from 3 × Blackstone (other recipes also exist). It is mined with a pickaxe.
