Overview
In Minecraft 1.21.4, Petrified Oak Slab is a building block. It is gathered by mining rather than crafted. At a hardness of 2 it takes a moment to break but never slows a build down.
It needs at least a wooden pickaxe to drop anything; a weaker tool destroys it for nothing. Mining it returns the block itself, so it is safe to relocate. No recipe takes it as an ingredient.
How long it takes to break
Petrified Oak Slab has a hardness of 2. By hand that is 10 seconds per block; with the correct tool at netherite tier it is 0.35 seconds.
An iron tool takes 0.5 seconds and a diamond one 0.4, so the jump that actually matters for this block is the one to iron.
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.
The Efficiency formula is level² + 1 added to tool speed — at V that is about 3.5 times the unenchanted rate.
| Tool | No enchantment | Efficiency III | Efficiency V |
|---|---|---|---|
| Hand * | 10 s | 10 s | 10 s |
| Wooden | 1.5 s | 0.25 s | 0.15 s |
| Stone | 0.75 s | 0.25 s | 0.1 s |
| Iron | 0.5 s | 0.2 s | 0.1 s |
| Diamond | 0.4 s | 0.2 s | 0.1 s |
| Netherite | 0.35 s | 0.2 s | 0.1 s |
| Golden | 0.25 s | 0.15 s | 0.1 s |
Properties
Petrified Oak Slab has a blast resistance of 6, so a nearby explosion will usually destroy it. It blocks light completely and emits no light of its own. 64 fit in a slot — a full stack. The block is tagged for pickaxes, and only that class gets the speed bonus; everything else mines at bare-hand rate. As furnace fuel it burns for 7.5 seconds — 0.8 smelting operations.
