Slabs are half-versions of their respective blocks.

Smooth blocks are full blocks featuring the top texture of their respective slabs on all six sides ‌[Java Edition only][upcoming: Lua error in Module:Version_link at line 112: attempt to concatenate local 'text' (a nil value).]

Obtaining

Stone-type slabs and smooth blocks require a pickaxe to mine. Wooden slabs can be mined with anything, but an axe is quickest.

Natural generation

Stone slabs can be found naturally in villages lining the roof of blacksmith shops and inside the Butcher's Shop and the Blacksmith where they form counters. They are also found in strongholds where they are used in some of the stairs, ledges and torch pillars. Sandstone slabs can be found naturally in desert villages, desert wells, and desert temples. Double stone slabs can be found in villages, in the butcher's shop and in blacksmiths. A spruce wood slab serves as a table in igloo basements. Oak, birch, spruce, stone and cobblestone slabs can also be found in woodland mansions.

Creative inventory

Smooth blocks can be found in Creative inventory.

Usage

Placement

Slabs can be placed either right side up or upside-down:

  • Pointing at a block top or the bottom half of a block side will place the slab right side up.
  • Pointing at a block bottom or the top half of a block side will place the slab upside-down.

Slabs cannot be placed on the other four axes.

Behavior

Upside-downRedstone

An example of how upside-down slabs can make redstone travel compactly "up stairs".

Redstoneless Slab

Slabs do not block a vertical redstone connection as it is a transparent block.

Slabs are treated as a whole block by other blocks and liquids. Two slabs can be piled on top of one another to make a full-size block, but different slab types cannot be mixed in this way.

Redstone can be connected to the wire on the side of the slabs. Redstone placed on top of an upside-down slab can receive signals from an adjacent block of redstone one block lower but cannot transmit signals to it. This is why "ladders" made from upside-down slabs, as pictured to the right, can transmit redstone signals up, but not down.

Mobs see a slab as a full block. Mobs can also spawn on the tops of upside-down slabs and double slabs, but not on lower slabs.

In Bedrock Edition, mobs standing on right-side up slabs fail to pathfind correctly. They seem to perceive the slabs beneath them to be unwalkable, and will often end up spinning around in a small circle when they try to move. The block directly beneath the slab must be air or another right-side up slab to disturb pathfinding. Also in Bedrock Edition iron golems will not spawn on a slab even if it is the top half of a block.

Due to the way blast rays propagate from an explosion, bottom-half slabs provide extremely effective absorption to explosions directly on top of them.

Sneaking only reduces the player's hitbox height to 1.65 blocks, and so does not allow the player to walk over a single slab with one block of air above it, which is 1.5 blocks of space. A player cannot walk from a block of soul sand directly up to a slab without jumping – this applies not just to soul sand, but to any block 78 of a block high or shorter, because the maximum step height of the player is 0.6 of a block. The player can walk off a slab while sneaking, because the sneaking only prevents falling when the distance is higher than one half block.

If a slab is placed underwater, the empty half of that slab's block will appear and act as air. If the slab is upside-down, not only can the player grab a quick breath of air there, but the player can see as clearly as if they were above the surface.

Minecarts on powered rails will not be repelled from a slab. They will, however, be repelled by a slab with a minecart on top.

Falling block entities (like sand, gravel, and concrete powder) will turn into their dropped form if they land on a slab, exactly like what occurs when they fall on a torch.

Fuel

Wooden slabs can be used as a fuel in furnaces, smelting 0.75 items per slab in the Java Edition and Console editions, and smelting 1.5 items per slab in Bedrock Edition.

Data values

The slab blocks use IDs and data values to differentiate between types. They also have block states which will replace data values in the future.

beta
1.3Sandstone SlabFile:Oak Slab pre-Beta 1.9 Prerelease 5.pngFile:Cobblestone Slab pre-Beta 1.7.png Added sandstone, "wooden" and cobblestone slabs as variants of the stone slabs. All had the same properties as stone slabs, apart from using different textures.
The original wooden slabs had the oak plank texture, the only plank type at the time. Being variants of the stone slabs, they had to be mined with a pickaxe to collect, were not affected by fire, and had stronger blast resistance than wooden planks, making them a useful building material. The only way to obtain this slab on current versions is by using commands. The item tooltip will say "Wooden Slab" rather than "Oak Wood Slab", and the item form is a large full block with the missing texture until 17w47a.
Before the additional slabs were added, a double stone slab would only yield one slab when broken. Since this update, all double slabs yield 2 of their respective single slabs when broken. Destroying double slabs with TNT, however, still only yields single slabs (when the slabs aren't simply destroyed by the explosion).
Before Beta 1.3 came out, stone slabs were made with cobblestone instead of stone, but this update introduced cobblestone slabs to the game and changed the recipes for pressure plates and stone slabs so that there wouldn't be any conflicting recipes.
1.7Cobblestone Slab Updated the texture of the cobblestone slab.
1.8?Stone Brick SlabFile:Brick Slab pre-Beta 1.9 Prerelease 5.pngSmooth Stone Added the stone brick, bricks, and smooth stone double slab. (Smooth stone double slab was only obtainable through inventory editing until 17w47a.)
The sprinting feature was added in this update. While stairs stopped the player's sprinting at the time, slabs allowed a player to continue sprinting.
release
1.0.0Beta 1.9 Prerelease 5Oak SlabBrick Slab Updated the textures of bricks and planks, and by extension that of the slabs.
1.2.11.2-preAll types of slabs were now able to be placed upside down and under blocks; these occupy the top half of their block space rather than the bottom half.
The crafting recipe changed so that 6 slabs would be crafted rather than 3. The prior restriction was likely due to the fact that the slab types were differentiated by their damage values instead of by different data values, similar to wood, coal or charcoal, and colored wool.
1.3.112w17aOak SlabBirch SlabSpruce SlabJungle Slab New slabs were added for the four different types of wood planks, replacing the old wooden oak/"stone" slab. These new slabs were vulnerable to fire, and could be collected faster with an axe than with a pickaxe. Wooden slabs already crafted or placed in the world remain the old 'stone' type.
12w21aSandstone slabs now generate in desert temples.
12w25aRedstone (including repeaters, torches, levers, and pressure plates) and rails can now be placed on slabs and stairs positioned upside down.
12w26aMobs can now spawn on upside down slabs.

12w49aNether Brick Slab Added nether brick slabs, which causes the smooth stone double slab to change its data value to 43:7
1.5January 22, 2013Jeb states that the "smooth stone full half-slab" will be re-implemented with a data value of 43:8. Other slabs with data values of 43:9-43:15 will also use the top texture on all sides, resulting in a "smooth sandstone block" with a data value of 43:9. He also stated that they may be obtained legitimately later.[2]
13w01aWooden Slabs can now be used to craft daylight sensors.
13w02aQuartz Slab Added quartz slabs, featuring the top quartz texture on all six sides. The formerly unused slab type, known as the smooth stone slab, was removed from the game. Its data values were replaced with the nether quartz slab.
13w04aSmooth Sandstone The smooth stone double slab is re-implemented with a data value of 43:8. The smooth sandstone double slab is also added, with a data value of 43:9.

Trivia

  • Slabs let a small amount of light pass through their edges. This light is only visible with Smooth Lighting is turned on, and does not affect mob spawning or other light-dependent processes.
    • The exception of this is that any light directed through a slab does not affect any block's light values north of the source.
  • Whereas 1x1 dents in a flat floor using slabs are darkened as one would expect, 1x1 dents created using 2x1 or 2x2 stairs will darken less, due to having fewer surrounding solid blocks. This is a completely intentional feature.[3]
  • When water or lava are on top of an upside-down slab, the water dripping particles will appear in midair below the slab instead of from the slab itself, this may be eventually fixed on the Java Edition[4] but is an intentional feature on the Bedrock Edition.[5]
  • Once, there were dirt slabs.
