Stone, also known as "Smooth Stone" and "Clear Stone," is the most common Block in the Overworld, after Air, in Minecraft. It turns into Cobblestone when mined after Beta, unless using a Pickaxe with the Silk Touch enchantment. Also, after Beta, it is possible to turn Cobblestone into Stone by cooking inside a Furnace. Stone cannot be used to make Buttons and Stone Pressure Plates, for Cobblestone is meant to be used in those recipes.
2 Stone= 1 Stone Pressure Plate
1 Stone= 1 Stone Button
