Obtaining

Breaking

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

Most slabs drop themselves when broken. The exception is petrified oak slabs, which drop normal oak slabs.‌^{[Bedrock Edition only]}

Double slabs drop 2 of their respective single slabs, even when mined with Silk Touch. In Java Edition, double slabs are completely unobtainable.In Bedrock Edition, they can be obtained through inventory editing.

Stonecutting

Petrified Oak Slabs are the stone-type wooden slabs left from before Java Edition 1.3.1. They are now unobtainable in vanilla survival. However, they can be retained from worlds played in versions where they were legitimately obtainable.

Natural generation

• Smooth stone slabs generate naturally in strongholds.
• Sandstone slabs generate naturally in desert wells, and desert pyramids.
• Spruce slabs generate naturally in igloo basements.
• Oak, birch, spruce, smooth stone and cobblestone slabs generate naturally in woodland mansions.
• Dark oak, cobblestone and mossy cobblestone slabs generate in pillager outpost.
• Oak, birch, spruce, jungle, acacia, and dark oak slabs can generate in shipwrecks.
• Blackstone and Quartz slabs generate in bastion remnants.
• Purpur slabs generate naturally in end cities.

Villages

• Smooth stone, oak and cobblestone slabs generate naturally in plains villages.
• Smooth sandstone and sandstone slabs generate naturally in desert villages.
• Smooth stone and acacia slabs generate naturally in savanna villages.
• Smooth stone and spruce slabs generate naturally in taiga and snowy taiga villages.

Ruined Portal

• Stone, stone brick, and mossy stone brick slabs generate in ruined portals in the overworld.
• Blackstone, polished blackstone, and polished blackstone brick slabs generate in ruined portals in the nether .‌^{[Java Edition only]}
• Nether brick slabs generate in ruined portals in the nether.‌^{[Bedrock Edition only]}

Usage

Placement

Slabs can occupy either the top half or the bottom half of a block, or both:

• Placing a slab on top of a block or on the side of a block in the lower half of the side surface creates a bottom slab
• Placing a slab on the underside of a block or on the top half of the side surface creates a top slab
• Placing a top and bottom slab of the same type in the same block creates a double slab block
• It's impossible to place two different kinds of slabs in the same block.

Slabs cannot be oriented vertically.

Behavior

An example of how top slabs can make redstone travel compactly "up stairs".

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

A top slab or bottom slab is transparent to light in Bedrock Edition. A double slab is opaque.

A bottom placed on top of a hopper is transparent to items; the items fall through the bottom slab into the hopper. Without a hopper attached below, a bottom slab behaves as a solid surface.

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

Mobs see a slab as a full block. Mobs can spawn on top slabs and double slabs, but not on bottom slabs.

Generally, the top face of top slabs, the bottom face of bottom slabs, and all faces of double slabs are handled as solid blocks. Due to this, transparent blocks that need to placed on an opaque surface can be placed on these faces.

Double slabs are handled as a single block instead of two different slabs; as such, breaking one destroys the whole block and drop two slabs, as opposed to breaking only one slab within the block. "Double slabs" that are not aligned to the grid (i.e. a bottom slab on top of a top slab) are handled as separate blocks and are broken individually.

Redstone dust placed on a top slab receives signals from redstone dust one block lower and adjacent, but cannot transmit signals down to that block.

In Bedrock Edition, mobs standing on bottom slabs with air or another bottom slab below fail to pathfind correctly. They often end up spinning around in a small circle when they try to move.

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

Sneaking reduces the player's hitbox height to 1.65 blocks in Bedrock Edition, and so does not allow the player to walk over a bottom slab with one block of air above it, which is 1.5 blocks of space. In Java Edition, however, a crouching player's hitbox is exactly 1.5 blocks, allowing the player to fit through such a gap. A player cannot walk from a block of soul sand directly up to a bottom slab without jumping – this applies not just to soul sand, but to any block ⁷⁄₈ 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 bottom slab while sneaking, because the sneaking prevents falling only when the distance is higher than one half block.

If a single slab is placed in a water source block, the empty half of that slab's block is waterlogged. If a slab is placed in flowing water, a pocket of air is created in the unfilled half of the block. If the player's head is in this pocket, the player can breathe and see as clearly as from an air block. If a single slab is placed in between two water sources or waterlogged blocks, the slab becomes waterlogged. This also happens when a water bucket or a bucket containing a fish is used on a single slab. Double slabs cannot be waterlogged.

A minecart on powered rails is not repelled by a slab, although it is repelled by a slab with a minecart on top.

Fuel

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

History

Java Edition pre-Classic
May 16, 2009					Notch mentions wanting to add "half-height tiles for stairs".
Java Edition Classic
May 17, 2009					Slabs were suggested on the TIGSource forums.
October 22, 2009					Dirt slabs were shown in a blog post.
October 23, 2009					Notch says the new half block has nearly been finished and gives a video.
0.26 SURVIVAL TEST					Stone slabs have been introduced to the game.
					Stone slabs can be obtained by mining coal ore because of the lack of inventory and crafting.
					Slabs were originally called stairs.
Java Edition Indev
0.31		20100129			Slabs have now received a crafting recipe: 3 slabs from 3 cobblestone.
					Slabs no longer drop from coal ore.
Java Edition Beta
1.3					Added sandstone, "wooden", cobblestone and smooth stone slabs as variants of the stone slabs. All had the same properties as stone slabs, apart from using different textures.
					Smooth stone double slabs are obtainable only through inventory editing, and they use data the data value "4". These slabs are converted into brick slab when upgrading to Beta 1.8.
					The original wooden slabs have to be mined with a pickaxe to collect, were not affected by fire, and had stronger blast resistance than planks, making them a useful building material.
					Before the additional slabs were added, a double stone slab would yield only one slab when broken. Since this update, all double slabs now yield 2 of their respective single slabs when broken. Destroying double slabs with TNT, however, still yields only single slabs (when the slabs aren't simply destroyed by the explosion). It is not known when or if this was fixed.
					Before Beta 1.3 came out, stone slabs were made with cobblestone instead of stone, but this update has now 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.
1.7					Bottom slabs now use the bottom half of the double slab texture rather than the top.
					The texture of cobblestone slabs has been changed.
1.8		Pre-release			Added the stone brick and bricks slabs.
					Smooth stone double slabs now use the data value "6".
					The sprinting feature has been added in this update. While stairs cancel the player's sprinting, slabs allow a player to continue sprinting.
Java Edition
1.0.0		Beta 1.9 Prerelease 5			The textures of bricks and planks have been changed, and by extension that of the slabs.
1.2.1		1.2			All types of slabs are 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 has been 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.
1.2.4		release			The texture of sandstone slabs has been changed slightly, altough it is only visible in the double and bottom variants.

Trivia

• Any light directed through a slab does not affect any block's light values north of the source.
• Whereas 1×1 dents in a flat floor using slabs are darkened as one would expect, 1×1 dents created using 2×1 or 2×2 stairs darken less, due to having fewer surrounding solid blocks.
• When water or lava are on top of an upside-down slab, the water dripping particles appear in midair below the slab instead of from the slab itself, this was fixed in Java Edition 1.13-pre7, but is an intentional feature in Bedrock Edition.
• When a TNT placed on a slab explodes, its blast radius is greatly reduced. ( In some cases, only the slab is destroyed. )
• As with the previous trivia, End Crystals and Creeper explosions will also be weakened if the explosion happens on the slab.
• Slabs are the most efficient way to produce renewable charcoal fuel in Bedrock Edition. 3 wood blocks → 12 planks → 24 slabs for smelting 36 wood blocks into charcoal, which in turn can smelt 288 items. In Java Edition, the most efficient way to produce charcoal is to use planks as fuel to smelt wood blocks without crafting the planks into slabs.
