Stone can only be successfully mined with a pickaxe and will drop cobblestone, which is used in many crafting recipes and as a sturdy building material. Stone can also be successfully mined with a pickaxe enchanted with Silk Touch and will then drop one stone block. If it is not mined with a pickaxe, then it will drop nothing. Cobblestone can be smelted into smooth stone again. Stone can be used as a building material as well and can be used in several crafting recipes. Stone takes slightly less time to mine than cobblestone. Stone can be made by having lava flow on top of water.
