Polished Blackstone Wall — Minecraft block

Overview

Polished Blackstone Wall counts as a Nether block in Minecraft 1.21.4. A crafting table turns its ingredients into Polished Blackstone Wall. Its hardness of 2 makes it a normal, unhurried block to mine.

Anything below a wooden pickaxe breaks it without leaving a drop. It drops as the same block you mined. It stacks to 64.

You make it with Polished Blackstone. You can also cut it from Blackstone on a stonecutter. It is not used in any crafting recipe.

How long it takes to break

Polished Blackstone Wall sits at hardness 2: 10 seconds per block with your fists, 0.35 with the correct netherite tool.

You are looking at 0.5 seconds on iron and 0.4 on diamond — the iron step is where the time actually falls.

It will break below wooden, and you will get nothing for it. That combination of time spent and drop lost is the classic mining mistake.

Efficiency adds its level squared plus one to the tool speed, so Efficiency V is about 3.5 times faster than the same tool unenchanted.

Properties

Blast resistance on Polished Blackstone Wall is 6, so an explosion nearby will usually take it out. It stops light entirely and gives off no light. One inventory slot holds 64, the normal full stack. A pickaxe is the fastest choice here. A tool of the wrong class is no better than your fist — the speed bonus is tied to the block's own tool tag.
