Smooth Stone block in Minecraft
Smooth Stone is stone baked a second time in a furnace, with a flat gray face and a thin border.
It is obtained in the Furnace from Stone. It is mined with a pickaxe.
What it does
Smelt Stone to get it; stone itself comes from smelting cobblestone, so smooth stone takes two passes through the furnace. Mason villagers' chests sometimes hold a few.
Three smooth stone are part of the Blast Furnace recipe, and smooth stone slabs are a classic for flat roofs and floors. The block has only a slab, no stairs or wall.
