Polished Blackstone is a refined version of blackstone, commonly used as a decorative building block. It can be crafted by combining blackstone or obtained through stonecutting.
Polished Blackstone can be further crafted into bricks, slabs, stairs, walls, buttons, and pressure plates. It has a higher hardness than its chiseled variant and can substitute for cobblestone in some crafting recipes. When placed under a note block, it produces a 'bass drum' sound.
