Cobblestone generators are a stimulating concept to the sport, they’re far and away most ordinarily seen within the “Skyblock” game mode, in which players typically have a really limited amount of starting resources at their disposal.

A cobblestone generator, if built correctly, essentially allows you to spawn an infinite amount of the latest cobblestone blocks to create with. In typical vanilla Minecraft survival, this may likely prove somewhat useless, however, in special ultra-low resource-based game modes (such as skyblock), cobblestone generators are imperative to progression.

It is often difficult for beginners to build a cobblestone generator correctly the primary time, this guide however will explain in basic terms how you’ll build one and can also discuss all of the resources required to try to do so.

Material Required for Cobblestone Generator:

Materials you will need in order to craft a Cobblestone generators are: 

  • 1 Lava bucket
  • 1 Water bucket

Once you’ve got made two buckets, you’ll get to locate a source of both water and lava, then you want to interact with said liquids while holding an empty bucket so as to fill it up.


Water can very easily be found within a couple of minutes of exploration of the planet, it’s also typically given to players playing the skyblock game mode upon spawn. Lava buckets are also typically given upon spawn when playing skyblock.

How to make Cobblestone Generator in Minecraft?

In a Nutshell:

To make a cobblestone generator, dig a 1×4 rectangular trench with the second block from the proper side being 2 layers deep rather than the traditional one. Then add water/ice on top of the block furthest to the proper of the ditch, finally, add lava on top of the block furthest left of the trench. A block of cobblestone should automatically spawn upon this placement.

Step-by-Step Guide:

Here is the step-by-step guide you need to follow to make Cobblestone Generator in Minecraft:

  1.  Dig a rectangular trench.
  2. Add water/ice on top of the block furthest to the right of the trench.
    1. Tip: If you’re using an ice block rather than a water bucket, confirm to put the ice block down, then break it to spawn water!
  3. Add lava on top of the block furthest left of the trench.
  4. If you have done everything right, a block of cobblestone should automatically spawn.

How to use a Cobblestone Generator in Minecraft?

If you’ve got followed the steps within the guide above and have access to a working cobblestone generator, you ought to be ready to simply break the cobblestone block spawned by the colliding water and lava blocks within the middle.

Provided you’ve got built the generator correctly, this cobblestone block should respawn upon being broken indefinitely; meaning you’ll break the block as repeatedly as you wish and a replacement one will always be spawned.

Frequently Asked Questions (FAQs)

1. How do you build an AFK cobblestone generator farm?

Automatic harvesting farms (AFK farms) are often tons more complex to assemble than anything covered during this beginner tutorial.

2. How many buckets of lava/water do I need to make a cobblestone generator?

Provided you create no mistakes in assembly, you ought to only need 1 bucket of water and 1 lava bucket to create an efficient cobblestone generator.


Cobblestone generators are rarely seen in vanilla Minecraft survival, mainly thanks to the sheer natural abundance of stone and hence cobblestone within the planet. There are actually billions of stone blocks that spawn naturally within any world, making a cobblestone generator pretty useless to mention the smallest amount.

Resource constraining game modes such as skyblock however are where most players have an interest in building cobblestone generators. In these specific game modes, it becomes almost impossible to form any real progress without a working generator assembled so as to consistently provide you with a gentle stream of the latest building blocks.
