Petrified Oak Slab

Petrified oak slabs are a unique type of slab only available from the Creative inventory, commands or upgrading from legacy versions - unlike all other slabs, they are unobtainable through conventional Survival gameplay.

Obtaining
Petrified oak slabs are unobtainable in new Survival worlds.

Breaking
Petrified oak slabs require a pickaxe to mine, dropping themselves when broken.

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

Upgrading
Petrified oak slabs are obtainable and craftable as one would expect in versions released before Java Edition 1.3.1, in which they are the only wooden slab type.

Usage
Petrified oak slabs are functionally still slabs, and share the majority of their placement, collision and other such behaviours with normally obtainable slabs.

Before unique slabs corresponding to different wooden planks types were added, oak wooden slabs were treated like other stone-type slabs. They required a pickaxe to break, had a blast resistance greater than normal planks, had stone sounds and fire could not spread to them. They are still obtainable in worlds, which had them in it previously. They are tagged as Wooden Slab, reflecting on the fact oak was the only wood type in plank form, and drops normal oak wood slabs when broken. This slab is still obtainable with commands, with damage value 2 and block type stone_slab. These were never truly exclusive to the Bedrock Edition, as they are essentially parallel to the petrified oak slabs $$; only the name and drops are unique.

Differences from normal slabs
Petrified oak slabs are mostly notable for where their behaviour diverges from that expected of their name and appearance.

Unlike other wooden slabs:
 * Petrified oak slabs make the sounds characteristic of stone.
 * They require a pickaxe to mine.
 * If broken with anything but a pickaxe, they will drop nothing.
 * They are not flammable.
 * They cannot be used as fuel in a furnace.
 * They have more blast resistance.

Unlike other slabs in general:
 * They cannot be crafted, or indeed obtained normally in Survival.
 * They do not have a direct full-block equivalent.
 * They do not drop themselves, but rather drop another type of slab: the oak slab.
