Cobblestone in Minecraft: generators and basic uses

Cobblestone is what stone drops when mined without Silk Touch, so you have plenty as soon as you start mining. It needs a pickaxe to collect; by hand it takes longer and drops nothing. It is the material for the first stone tools, the furnace and plenty of early-game building.

As a building block it has fairly high blast resistance for something so common, which is why it is the usual choice for a first shelter. It also repairs stone tools at an anvil: sword, pickaxe, axe, shovel, hoe and spear.

The most useful mechanic around it is the cobblestone generator. When water touches flowing lava, that lava turns into cobblestone; if the lava flows down onto the water you get stone instead, and if water reaches a still lava source you get obsidian. A well built generator gives you endless cobblestone without moving.

It generates ready-placed in monster rooms, jungle pyramids, pillager outposts, strongholds, villages and woodland mansions. Silverfish can hide inside it and turn it into an infested block that releases a silverfish when broken.
