What is a Cobblestone Generator?
A cobblestone generator is a mechanism in Minecraft that creates an infinite source of cobblestone through the interaction of flowing lava and water. When lava flows into water (or vice versa), the contact point turns into cobblestone. This process can be repeated indefinitely, providing players with an unlimited supply of this essential building material.
Why Build a Cobblestone Generator?
There are several compelling reasons to build a cobblestone generator in your Minecraft world:
- Unlimited Resources: Never run out of cobblestone for your building projects
- Skyblock Survival: Essential for survival on limited-block islands
- Resource Efficiency: Save time by having a centralized mining location
- Automation Potential: Can be upgraded to fully automated systems
- Redstone Practice: Great introduction to more complex Minecraft mechanics
Basic Cobblestone Generator Tutorial
Gather Materials
You'll need 1 lava bucket, 1 water bucket, and about 10 building blocks (stone, dirt, etc.)
Create the Structure
Build a small 3×3 platform with a trench in the middle, making sure to leave a block gap between where the water and lava will be placed
Place the Liquids
Place water at one end of the trench and lava at the other, ensuring they flow toward each other
Mine the Cobblestone
As the liquids meet, cobblestone will form. Mine it and it will continuously regenerate
Skyblock Cobblestone Generator
In Skyblock mode, resources are extremely limited, making an efficient cobblestone generator vital for survival and progression. The Skyblock design is more compact and usually includes safety features to prevent losing the precious lava or water sources.
The most popular Skyblock design uses a simple 2×2 formation with a diagonal placement of water and lava. This ensures the cobblestone forms at a predictable location and prevents the player from accidentally falling into the lava while mining.
Automatic Cobblestone Generators
For players looking to eliminate manual mining, automatic cobblestone generators offer a sophisticated solution. These designs use pistons, redstone, and sometimes TNT to automatically break the cobblestone as it forms.
Key Components for Automatic Generators:
- Observer Blocks: Detect the formation of cobblestone
- Pistons: Push or break the newly formed cobblestone
- Hoppers and Chests: Collect and store the mined cobblestone
- Redstone Circuitry: Coordinate the timing of the system
More advanced designs can produce hundreds of cobblestone blocks per hour without any player interaction, freeing you up to focus on other aspects of your Minecraft world.
Bedrock Edition Considerations
While the basic principles of cobblestone generators work across all Minecraft versions, there are some important differences in Bedrock Edition:
- Lava flows faster in Bedrock Edition, potentially affecting generator timing
- Some redstone mechanics work differently, requiring modified designs
- Piston behavior varies slightly, especially for more complex automatic designs
Our tool automatically adjusts designs based on your selected Minecraft version to ensure compatibility.
Troubleshooting Common Issues
Cobblestone Not Forming
Water and lava aren't meeting at the correct angle or distance.
Solution
Ensure the water and lava flow directly toward each other with exactly one block space for the cobblestone to form.
Obsidian Forming Instead
Water is flowing onto the lava source block.
Solution
Ensure the lava is flowing (not a source block) at the point where it meets the water.
Stone Forming Instead
Lava is flowing onto a water source block.
Solution
Make sure the water is flowing (not a source block) at the point where it meets the lava.
