Minecraft does not like to obey the laws of physics, and the law of conservation of mass is not an exception. Cobblestone generators in Minecraft will generate cobblestone indefinitely. They prove to be very helpful for collecting building materials and a necessity for surviving in SkyBlock. Here is a simple guide on making a cobblestone generator.
Steps
-
1Gather your materials. You’ll need 3 iron for a bucket, a source of lava, and a source of water. Mine iron underground or look for it on the walls of a cave. Smelt the iron in a furnace and then craft a bucket. Lava sometimes appears in pools on the surface, but you’ll need to get underground below Y:9 for them to be common.
- Craft two buckets if you want to carry both the lava and water at the same time.
- Some cobblestone (or another non-flammable block) can be used to reduce the chance of the generated cobblestone falling in lava.
- If you are playing SkyBlock, you may have a block of ice instead of a water bucket. You can place the ice down and break it to get water.
-
2Dig a one block deep hole and a two block deep hole next to it. Place the water in the one block deep hole so that it flows into the two block hole.
- If the water turns the lava into obsidian, you may not have dug the second hole two blocks deep.

3Leave a gap of one block and dig another one block deep hole. Place your lava here.
-
4Break the block separating the lava and water. After about a second, there will be a hissing sound and a cobblestone block will form.
-
5Continue breaking the cobblestone. The generator will continue to produce infinite amounts of cobblestone.
-
6Improve your generator. Cover up the lava and water so that you don’t fall into it with non-flammable blocks (cobblestone, dirt, clay, etc.). This will also help prevent cobblestone you mine from being burned by the lava. Break a block in front of the generator to stand in so that you can mine and pick up your cobblestone more easily.

QuestionWhen I built the first one, all of the lava kept melting the cobble when I broke it. How can I stop this from happening?
MelodyTongyuCommunity AnswerMy suggestion is to dig a hole beside the cobble (where you won't touch any lava or water) and jump in before you mine the cobble. Then, walk into the cobble as close as you can and stay there. When you mine the cobble, it's more likely to go into your inventory. You can also use a hopper under the generator so that when you mine it, the cobble will go into the hopper. -
QuestionCould I place cactus so that when I push the piston, the cobblestone is moved next to the cactus, then the cactus makes it break?
CaptianYayaCommunity AnswerNo. This will break the cactus instead of the cobblestone. -
QuestionHow do I do it if Tile Drops (console editions only) is disabled?
Frail HunterCommunity AnswerEnable them or use a different version than you're currently on.
Warnings
- Avoid building the generator on a surface that's above your house or other important items. Lava travels downhill, so if the generator breaks, it's safer to keep it lower than your stuff.⧼thumbs_response⧽
- Make sure your generator is away from trees and wooden buildings. The lava can set them on fire from further than you'd think and you may accidentally spark a wildfire.⧼thumbs_response⧽
