Oak Slab is a wooden slab variant crafted from oak planks. It can be placed as a half-block or stacked to form a full block. Oak slabs generate naturally in structures such as plains villages, woodland mansions, shipwrecks, and trial chambers.

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