Black Wool Slab is a half-height block made from wool. It is crafted from Black Wool, or by combining Black Dye with a Blue, Brown, Cyan, or Gray Wool Slab. When broken, it drops itself.

Players use it as a building material, and it is an ingredient in 16 crafting recipes. It can also be waterlogged, so it can hold water inside the same space.
