Cobblestone Farm & Block Generator Schematics

Block generators make renewable building blocks from fluid interactions. Flowing lava that touches water turns into cobblestone, and lava flowing down onto water turns into stone. Lava next to blue ice, above soul soil, forms basalt. A generator holds the lava and water in place so a new block forms every time you mine the old one.

Manual generators let you stand in one spot and mine with an Efficiency pickaxe, often with several outputs so the next block is always ready. Larger automatic designs break the blocks with TNT or other machines and collect them with hoppers. Smelting cobblestone gives stone, and some builds also make concrete, which forms when concrete powder touches water, or mud from water bottles used on dirt.

Compare each design's size, output block and how it is mined, and check the Minecraft version and any game mechanics the creator says it depends on. If you need a .schem file for WorldEdit, use the converter.
