Cobblestone Slab

Cobblestone Slabs are craftable blocks, crafted using three cobblestone in a horizontal line. Cobblestone slabs behave like Stone Slabs. They were introduced in Beta 1.3

Although cobblestone slabs, wood slabs, sandstone slabs, and stone slabs can be put on top of each other, you cant have two different slabs directly on top of one another, this is shown in this video.



Trivia
The Cobblestone Slabs are currently named "Stone Slabs" ingame, even if they do look like and are crafted from Cobblestone.

Pre 1.3 update the Cobblestone Slab recipe created a slab that used to resemble the smooth slab. After the update the player has to create stone blocks to create the former smooth stone slabs.
