Polished Deepslate Stairs — Minecraft block

Overview

In Minecraft 1.21.4, Polished Deepslate Stairs is a stone-family block. Polished Deepslate Stairs is made at a crafting table. Expect to wait: its hardness of 3.5 is well above average.

Mine it with a wooden pickaxe or better, or you get no drop at all. Broken correctly, it drops itself. Sixty-four fit in one inventory slot.

The recipe calls for Polished Deepslate. A stonecutter can cut it straight from Cobbled Deepslate, with nothing wasted. Nothing on the crafting grid is made from it.

How long it takes to break

Polished Deepslate Stairs sits at hardness 3.5: 18 seconds per block with your fists, 0.6 with the correct netherite tool.

You are looking at 0.9 seconds on iron and 0.7 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 contributes its level squared plus one to tool speed, which makes Efficiency V roughly 4 times faster than the plain tool.

Properties

Polished Deepslate Stairs resists blasts at 6, which usually is not enough when something explodes nearby. Light does not pass through it, and it emits none of its own. Stack size is 64 — the standard 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. As furnace fuel it burns for 15 seconds — one and a half smelting operations.
