How to make a Cobblestone Generator in Minecraft

It may not be the hardest material to find, but sometimes you still need a Cobblestone Generator.

Cobblestone can seem like the easiest material in the world to gather in Minecraft, as there’s stone everywhere. But even so, there are situations where it’s just easier to have a bunch of cobblestone generated as quickly as possible. So check our our simple guide to making a cobblestone generator!

The Basic Concepts of a Minecraft Cobblestone Generator

To make a cobblestone generator, you need to use the interaction between flowing lava and water. When water comes in contact with a space occupied by flowing lava in Minecraft, it creates a cobblestone block.

However, if water hits a source block of lava, it creates obsidian, destroying the source. Vice versa, if lava hits a water source block, it evaporates the source. To solve this problem, we use the fact that water and lava only flow at certain speeds and distances to our advantage.

Water will flow seven blocks from its source. However, lava will only flow three blocks. We use this knowledge to create a 12 block long (two extra blocks for the sources) canal for both materials to flow along. After placing them both at opposite ends, a cobblestone block will be formed in the middle.

Mine the cobblestone block, and another will almost instantly be formed. You’ve now completed your first cobblestone generator!

Advanced Cobblestone Generators

Once you have the basic recipe down, you can create far more elaborate and advanced generators, place them inside or underground, and generally go wild with them. You can even build them in places where no cobblestone can be mined naturally, such as The End.

One thing you should consider adding is a small pool of water nearby. Working with lava can always be dangerous, and a small pool of water could save a life. Adding hoppers and chests for automatic retrieval might also be a great addition. But overall, the same basic concept remains: Protect the source blocks and make a meeting point between lava and water.
