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.

Contents

Obtaining

[edit | edit source]

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

[edit | edit source]

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

Legend
  • incorrect tool, drops nothing
  • correct tool, drops nothing or something other than the block itself
  • correct tool, drops the block itself
  • italicized can be instant mined
  1. ↑ These durations ignore any other influential factors (e.g., Mining Fatigue) and are measured in seconds. For more information, see Breaking § Speed.

Crafting

[edit | edit source]

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

Upgrading

[edit | edit source]

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

[edit | edit source]
Main article: Slab § 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

[edit | edit source]

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

[edit | edit source]

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

History

[edit | edit source]

Java Edition

[edit | edit source]
Java Edition Beta
1.3Added 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.
Java Edition
1.2.11.2Wooden slabs can be placed in the top half of blocks.
The crafting recipe has been changed to produce 6 wooden slabs instead of 3.
1.3.112w17aA 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).
1.1317w47a"Wooden Slab" has been renamed to "Petrified Oak Slab".
Petrified oak slabs have been made available in the Creative inventory.
1.19.322w42aPetrified oak slabs are no longer in the Creative inventory.

v0.7.3Wooden 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.
v0.11.0build 1"Fake Wood Slab" has been renamed to "Wooden Slab".
Bedrock Edition
1.21.0Preview 1.21.0.23Removed wooden slabs. Existing wooden slab blocks and items in old worlds are converted into oak slabs.

1.8?With the addition of block states, the state used for these slabs has a specific name: wood_old and the variant name: old_wood_slab. The item texture was missing for having a variant name that was not registered in the model item rendering code and in the game assets item model.
1.1317w47aPrior to The Flattening, these blocks' numeral IDs were 43 and 44.

Bedrock Edition

[edit | edit source]
Pocket Edition Alpha
v0.1.0Wooden slabs are added with the stone_slab ID, however their item form's ID is incorrectly registered as double_stone_slab.
The direct item form of double wooden slabs have the real_double_stone_slab ID.
Bedrock Edition
1.19.0Preview 1.19.0.27The IDs of wooden slabs and double wooden slabs have been changed to stone_block_slab and double_stone_block_slab respectively.
1.20.30Preview 1.20.20.20Wooden slabs now use the minecraft:vertical_half block state instead of top_slot_bit.
1.21.0Preview 1.21.0.23The ID of wooden slabs have now been merged with the regular oak slab (oak_slab), effectively removing wooden slabs completely. Wooden slabs placed before the preview 1.21.0.23 are converted to oak slabs.
Double wooden slabs still exist.
Preview 1.21.0.25Re-added wooden slabs, now with a new ID: petrified_oak_slab.
1.21.20Preview 1.21.10.20The different stone slab type block states for the double_stone_block_slab ID have been split up into their own IDs.

Nomenclature

[edit | edit source]

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