Dark Oak Slab is a wooden slab variant crafted from dark oak planks. It can be placed as a half-block or stacked to form a full block. Dark oak slabs are mainly used for decorative building and crafting.

Wooden slabs can be mined with any tool, but axes are the fastest. They can be used in crafting barrels, composters, lecterns, and daylight detectors. Dark oak slabs can also serve as fuel, smelting 0.75 items per slab. Additionally, they can be placed under note blocks to produce a bass sound.
