Sandstone Slabs are craftable blocks, crafted using three Sandstone in a horizontal line. Sandstone Slabs behave like Stone Slabs, and were introduced in Beta 1.3 alongside Wooden Slabs and Cobblestone Slabs.
Used for making lengthy stairs. Two slabs placed on top of each other will create a full-sized block. (The full-sized block looks like a regular block, but when mined drops 2 slabs.)
