Smooth Stone is a refined variant of stone, obtained by smelting regular stone in a furnace. It is primarily used for building and crafting specific items like blast furnaces and Smooth Stone slabs. Smooth Stone must be mined with a pickaxe; otherwise, it drops nothing. It has a hardness of 2, making it more durable than cobblestone but still relatively easy to break.

Naturally, Smooth Stone can generate in some village houses and inside mason chests. It is crafted by smelting stone and can be further cut into slabs using a stonecutter.
