Slabs are half-blocks. Upside-down slabs occupy the top half of their block space rather than the bottom half. To place a slab upside-down, right-click on the bottom of a "ceiling" block, which can be removed after the slab has been placed, or by right clicking the top half of the side of another block, if the player wishes to place it on the side of another double or single slab block.

All types of "stone" slab have the same data values; like wood and colored wool, they are differentiated by their damage values: stone slabs have a damage value of 0, sandstone slabs has 1, old wooden slabs has 2 (which were actually stone, and are still obtainable), cobblestone slabs has 3, bricks has 4, stone bricks has 5, and nether bricks has 6. Damage value 7 is occupied by nether quartz, and formerly by a smooth variant of the stone slab. Upside down stone slabs have a damage value of 8, sandstone has 9, wooden has 10, cobblestone has 11, bricks has 12, stone bricks has 13, nether bricks has 14, and nether quartz has 15. Real wood slabs use a different set of block and damage values.

Obtaining[edit]

Natural Occurrence[edit]

Stone slabs can be found naturally in villages lining the roof of a blacksmith shop and inside some of the buildings 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.

Crafting[edit]

Unlike many wooden items, wooden slabs must be crafted entirely from one type of wood, but by the same token, they keep the type (and color) of the wood used, thus "Birch Wood Slabs" and so forth.

Behavior[edit]

An example of how upside-down slabs can make redstone travel compactly "up stairs".
Slabs do not block a vertical redstone connection.

Like other partial blocks, slabs are treated as a whole block by other blocks, such as dirt, stone, and glass, and liquids. Two slabs of the same type (e.g. two stone slabs) can be placed one on top of one another to make a single full-size block, but different slab types cannot be mixed in this way. Sandstone, wooden, and cobblestone double-slabs look exactly the same as their full block counterparts, but take a longer time to break and drop two slabs. Wooden slabs are collected more quickly with an axe and are flammable.

Single slabs have the tendency to let through arrows shot from above. They will also destroy gravel and sand blocks that fall onto them (the same as torches, as long as the slab is a bottom-half). They are also treated as transparent by the game and cannot cause suffocation, prevent placement of torches or other fixtures on them and chests with single slabs above them can still be opened.

An unusual property of slabs is that they are non-solid to redstone. This allows redstone wiring to be hidden underneath while still being able to connect to the wire on the side of the slabs. In addition, 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 can spawn on top of upside down slabs and on double slabs.

Due to the way blast rays propagate from an explosion, slabs provide extremely effective absorption to explosions directly on top of them. Specifically, this is because explosive entities will be lower in elevation when they explode on top of slabs than they would otherwise be on an ordinary block. Although the few slab(s) directly under the explosion will absorb the full force of the blast (with a resistance of 30) as usual, the propagation of damage to the sides will be greatly reduced. If source of the explosion is elevated for any reason at the time of the blast, this protective quirk is lost.

Despite how sneaking lowers the player's eye level half a block, doing so does not allow the player to walk over a single slab with one block of air above it because of the player's true height. A player cannot walk from a block of soul sand to a slab without jumping.

History[edit]

Classic
May 17, 2009 Slabs suggested on the TIGSource forums.
0.26 SURVIVAL TEST 4
Half-sized dirt block test.
0.26 SURVIVAL TEST 7 Half block nearly finished.
0.27 SURVIVAL TEST 10
Stone slabs were introduced to the game.
Stone slabs could be obtained by mining coal ore because of the lack of inventory and crafting.
At the time, slabs were called "stair" blocks before the introduction of what are currently called stairs in Alpha 1.0.0.
Indev
0.31 Slabs received a crafting recipe: 3 slabs from 3 stone.
Beta
1.3


Added sandstone, wooden, and cobblestone slabs.
A wooden "stone" slab house with a netherrack fireplace.
These old wooden slabs did not burn, and could only be collected with a pickaxe because they were the same block and shared the same data value as other slabs, except with a different texture. Wooden slabs would break faster with a pickaxe than with an axe. Wooden slabs were also are not affected by fire and had a stronger blast resistance than wooden planks, which made them a useful building material. These properties could be used in SMP to help prevent griefing, and the fact that they didn't burn also made them useful for creating houses in The Nether.
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.
1.8

Added the stone brick, bricks, and smooth full half-slab. (Smooth full half-slab was only obtainable through inventory editing at the time.)
The sprinting feature was added in this update. While stairs stopped the player's sprinting, slabs allowed a player to continue sprinting.
Official release
1.2.1 1.2-pre All 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.
1.3.1 12w17a



New slabs were added for the four different types of wooden 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. The original wooden oak/"stone" slab can still be obtained through inventory editing or the /give command. Wooden slabs already crafted or placed in the world remain the old 'stone' type.
All four wooden upside-down slabs had the oak plank texture.
12w18a Fixed upside-down slabs having same texture.
12w25a Redstone (including repeaters, torches, levers, and pressure plates) and rails can now be placed on slabs and stairs positioned upside down.
12w26a Mobs can now spawn on upside down slabs.
1.4.2 12w39a
upside-down slab lighting bug
Slabs interact properly with lighting now; when slabs are placed upside down, they now accept light from light sources themselves, and no longer block light to surrounding blocks; they no longer cast the shadow of a full-sized block.[1]
Smooth lighting on slabs is slightly bugged.
November 28, 2012 Jeb tweeted a picture of himself crafting nether brick slabs.
1.4.6 12w49a
Added nether brick slabs, which causes the smooth full half-slab to change its damage value to 43:7
1.5 13w02a
Added quartz slabs. The formerly unused slab type, known as the smooth full half-slab (see gallery), was removed from the game. Its data values were replaced with the nether quartz slab.
January 22, 2013 Jeb states that the smooth full half-slab will be re-implemented with a value of 43:8. The smooth sandstone slab will also be implemented, with a value of 43:9. He also stated that they may be obtained legitimately later.[2]
1.5 13w04a The smooth full half-slab is re-implemented with a value of 43:8. The smooth sandstone full half-slab is also added, with a value of 43:9.
1.7.2 1.7-pre

Added acacia and dark oak slabs.
1.8 14w02a Stone Brick slabs can now be used to craft Chiseled Stone Bricks.
Stone slabs could be crafted using granite, diorite, andesite, or their polished counterparts.
14w25a Double Stone slabs and Double Wooden slabs can no longer be obtained as an item.
14w32a
Added red sandstone slabs.
14w33a Stone slabs can no longer be crafted using granite, diorite, andesite, or their polished counterparts.

Dirt slab[edit]

The dirt slab, replacing all the dirt (not grass) blocks.

Before stone slabs were added to 0.26, Notch ran a test of dirt slabs. They were never added to the actual game and were only mentioned once.[3] They replaced all dirt blocks and did not grow grass on top.

Issues[edit]

Issues relating to "Slabs" are maintained on the issue tracker. Report issues there.

Trivia[edit]

Light passing through the sides of a brick slab from above. A normal block would render complete darkness.
  • An unused slab type, known as the "smooth full half-slab", has a data value of 438, but can only be placed using commands. It is a full block with the top texture of stone slabs on all six sides. A similar effect with sandstone can be obtained with 439. See the gallery for a comparison image.
  • 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.
  • When a slab is placed on top of ice, the slab has the same "slipperiness" as the ice below it. This applies to every other block with a hit-box less than a full block.
  • If slabs are placed below TNT, it will significantly reduce their damage. By making a floor of slabs, the TNT will lower its explosive power to two blocks instead of six. This is so because the TNT believes that it is inside the slab, for the game thinks that it is inside a full block, greatly reducing its explosion radius.
  • Mobs see a slab as a full block. Therefore, by placing an upside down slab above a slab with a block in between, there will be sufficient space for the player to walk through. Mobs, however, will see one block of space in between and won't get through. This does not apply to baby zombies and spiders, because they are only one block tall, and to slimes, as they will hop towards the player even if there is something obstructing the way.
  • Stone slabs are the only slab which, when stacked, do not mimic their block in texture.
  • You can sneak walk off slabs at ground level.
  • Minecarts on powered rails will not be repelled from a slab. They will, however, be repelled by a slab with a minecart on top.
  • Though wooden slabs are flammable, the old wooden oak/"stone" slab is still available through inventory editing or /give, so in a world/server where commands are allowed, it is possible to obtain fireproof wooden slabs.
  • When Creepers explode on stone slabs they only destroy the slab they were standing on and nothing else in the area.
  • It is possible to get any type of double slab that you want by using /give and typing in /give <player> stone_slab 1 [slab id]. This will allow you to build faster. There is not however any way to get a double slab in your inventory without commands, creative mode or mods.
  • If you type in /give <player> stone_slab 1 2, then it will give you a wooden slab or plank, but it acts like a stone block. It is not flammable and it makes "stone" sound effects when they are placed, broken, or stepped on. This is the version of the wood slab that was used for old slabs when wood slabs were made flammable.
  • If redstone dust is placed on an upside-down slab, it will not trigger adjacent TNT.
  • If you set a slab on the top half side of any block under water, it will displace as much of it as a whole block. Not only can you grab a quick breath of air, but you can see as clear through the water as looking over the land above the surface than in it itself.
  • When an upside down slab is pushed from the bottom by a piston (or regular slab pushed from the top), it is pushed without having contact from the piston. The same idea can also be made when pulled by a sticky piston.
  • Mobs can not spawn on single slabs that are right-side-up.
