Cobblestone

Cobblestone is a common block, obtained from mining stone. Its texture resembles block of stone with a largely cracked surface. It is mainly used for crafting or as building block.

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

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

Natural generation
Cobblestone occurs naturally in dungeons, jungle temples, pillager outposts, underwater ruins, strongholds, and woodland mansions. Cobblestone generates in all types of villages except desert.

Water and lava
When water and flowing lava come into contact, the flowing lava is replaced with 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.

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

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

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