Description

Polished Blackstone Brick Slab is a decorative half-height slab variant of polished blackstone bricks that generates in ruined portals in the Nether and serves as a building block. A crafting table converts three polished blackstone bricks into six slabs, and a stonecutter converts blackstone, polished blackstone, or polished blackstone bricks into two slabs per input. Any pickaxe breaks a polished blackstone brick slab, and mining without a pickaxe drops nothing. Polished Blackstone Brick Slab has a hardness of 2, a blast resistance of 6, and a stack size of 64.

Two polished blackstone brick slabs combine into one full double slab, so half-height detailing and solid dark masonry can share a single wall. Polished Blackstone Brick Slab does not catch fire, is not susceptible to lava, and can be waterlogged. Polished blackstone brick slabs are renewable: since Java Edition 1.16.2, piglins have an 8.71% chance to trade 8–16 blackstone during bartering, and each blackstone stonecuts into two slabs. For dark, layered floors, polished blackstone brick slabs give a lighter silhouette than full polished blackstone bricks.
