Cobblestone

Obtaining
Cobblestone requires a pickaxe to be mined, in which case it drops itself. If mined without a pickaxe, mining will be slower and it drops nothing. Its hardness is greater than stone so it requires more time to break.

Cobblestone is dropped by stone when mined without Silk Touch, and also by infested cobblestone when mined with Silk Touch.

Natural generation
Cobblestone occurs naturally in dungeons, jungle temples, pillager outposts, underwater ruins, strongholds, Plains, Taiga and Snowy Tundra Villages and woodland mansions.

Post-generation
When water and flowing lava come into contact, the flowing lava is replaced by cobblestone. However, if the lava flows on top of the water from above, stone is created instead. Non-flowing lava (a lava source block) turns into obsidian upon contact with water, thus the requirement of flowing lava.

Usage
Cobblestone can be used as basic building block, as it is blast resistant and extremely common.

Silverfish
Silverfish can enter and hide in cobblestone, creating an infested block.

Repairing
Cobblestone is one of the repair items for the stone tier and thus can be used to repair the following items in an anvil:
