A petrified oak slab, known generically as a wooden slab in Bedrock Edition, is a unique type of slab available through commands or by upgrading from legacy versions. Unlike all other slabs, they are unobtainable in vanilla Survival gameplay.

Obtaining

Petrified oak slabs are unobtainable in new Survival worlds. They can be obtained only by using commands such as /give or placed in the world using commands such as /setblock.

Breaking

Petrified oak slabs require a pickaxe to mine. When broken, they drop themselves in Java Edition or regular oak slabs in Bedrock Edition.

Crafting

Petrified oak slabs are uncraftable in current versions without the use of a data pack or behavior pack.

Upgrading

Petrified oak slabs are obtainable and craftable as one would expect in versions released before Java Edition 1.3.1 (snapshot 12w17a) or Pocket Edition v0.7.3 alpha, in which they are the only wooden slab type.

Usage

Petrified oak slabs are functionally like other slabs and share most of their placement, collision, and other block behaviors with them. They date back to the earliest releases when there was only one kind of wooden slab, which had the texture of oak planks but was implemented as a variant of the generic slab, all other variants of which were made of stone. It therefore had stone properties as well.

When other plank variants were introduced, true wooden slabs were added to the game with variants for each species and properties more appropriate for wood. From then on, all wooden slabs that were crafted or generated in structures were of the real wood type, but the stone variants can still exist in older worlds. These stonelike "wooden" slabs are noteworthy for how their behavior differs from what their name and appearance imply.

Differences from normal slabs

Unlike other wooden slabs:

• Petrified oak slabs make the sounds characteristic of stone.
• They require a pickaxe to mine. If broken without a pickaxe, they drop nothing.
• They are not flammable, nor are they set on fire by nearby lava.
• They cannot be used as fuel in a furnace.
• They have a greater blast resistance.
• Note blocks placed on top produce bass drum sounds, similarly to other stone-like blocks.

Unlike other slabs in general:

• They cannot be crafted or obtained normally in Survival.
• They do not have a direct full-block equivalent.
• In Bedrock Edition they do not drop themselves, but rather drop an oak slab.

Sounds

In Bedrock Edition, when a petrified oak slab is combined into a double slab, the block's use sound is played.^[1]

History

Java Edition

Java Edition Beta
1.3							Added petrified oak slabs.
							Petrified oak slabs were the "usual" wood slab in this version, as they were craftable from planks like all other slabs were, and accordingly named "Wooden Slab" in item form.
							Their behavior was due to sharing a block ID with all other slabs at the time, distinguished only by metadata, which could not define other block properties such as material and hardness.
							The crafting recipe originally only produced 3 wooden slabs. 3
Java Edition
1.2.1			1.2				Wooden slabs can be placed in the top half of blocks.
							The crafting recipe has been changed to produce 6 wooden slabs instead of 3. 6
1.3.1			12w17a				A separate block ID has been added for wooden slabs, to account for the addition of slabs with new wood types. This new ID also has the characteristics of normal wood blocks. As of this version, the petrified oak slab, still called "Wooden Slab", is now unobtainable, and can only be obtained by having them present in the world from previous versions (placed or as items).
1.13			17w47a				"Wooden Slab" has been renamed to "Petrified Oak Slab".
							Petrified oak slabs have been made available in the Creative inventory.
1.19.3			22w42a				Petrified oak slabs are no longer in the Creative inventory.

Bedrock Edition

Pocket Edition Alpha
v0.1.0							Added wooden slabs, which are currently unobtainable.
v0.2.0							The texture of wooden slabs has been changed to match that of planks.
v0.3.0							Wooden slabs can now obtained via crafting in Survival mode.
							Wooden slabs are now available in the Creative inventory.
v0.4.0							The model of bottom wooden slabs now uses the bottom half of the full block's texture.
v0.7.3							Wooden slabs have been renamed to "Fake Wood Slab" and are no longer obtainable except by using inventory editors. This was done to make way for the new wooden slabs with wood-like properties and multiple species.
							Fake wood slabs now drop the new wooden slabs.
v0.11.0			build 1				"Fake Wood Slab" has been renamed to "Wooden Slab".
Bedrock Edition
1.21.0			Preview 1.21.0.23				Removed wooden slabs. Existing wooden slab blocks and items in old worlds are converted into oak slabs.
							Double wooden slabs still exist.
			Preview 1.21.0.25				Re-added wooden slabs.[2]

Nomenclature

Petrified oak slabs are often referred as "alpha slabs" even though petrified oak slabs were added in Beta 1.3. In a similar case invalid data value leaves are often referred as "alpha leaves" even though other leaf types were added in Beta 1.2.
