Mangrove Slab is a wooden slab variant crafted from mangrove planks. It can be placed as a half-block or stacked to form a full block. Mangrove slabs are primarily 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. Mangrove 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.
