Ice Farm
Beginner Java + Bedrock
Produces: Ice for packed ice and blue ice - fast boat highways and non-melting build blocks
Quick answer: Water source blocks freeze into ice in snowy biomes when open to the sky, dimly lit, and next to a solid block. Dig a shallow pond in the snow, wait with Silk Touch in hand, and harvest sheet after sheet.
How it works
- The freeze conditions: snowy biome, water source open to the sky directly above, block light inside the water below 10, and at least one horizontally adjacent non-water block (even air counts) - then chunk ticks do the rest.
- Chunk ticks need a player nearby, like crops - an ice pond freezes only while someone is in the area.
- Light is the enemy: torches beside the pond push block light to 10+ and stop freezing - light the paths, not the water.
- Silk Touch or nothing: ice mined without it shatters into water (or nothing), so the whole farm runs on one enchanted pickaxe.
- Compression: 9 ice craft into packed ice and 9 packed ice into blue ice (81 ice per block). Blue ice does not melt near light and is the fastest boat surface (72.73 m/s against 40 m/s on ice or packed ice).
Materials
- A snowy biome - plains of snow, frozen river, frozen peaks
- Water buckets for the pond
- A Silk Touch pickaxe (non-negotiable)
- Building blocks for pond walls and a roof-free frame
- Patience: freezing runs on random chunk ticks
Build steps
- Scout the spot: any snowy biome with open sky works - frozen rivers come pre-dug.
- Dig the pond: one block deep, any shape, walled with solid blocks so every water block has a non-water neighbor.
- Fill with source blocks: still water only - flowing water does not freeze.
- Kill the light: no torches over the water; keep the block light inside below 10.
- Stand by: freezing advances on chunk ticks only while a player is close - fish, build or AFK nearby.
- Harvest with Silk Touch: break every sheet and the pond refreezes on its own.
- Compress: ice to packed ice (9:1) to blue ice (9:1) - 81 ice per blue ice block, and the farm makes it free.
- Build a blue ice highway for boats: top speed 72.73 m/s.
Rates
A 10x10 pond refreezes in a few minutes of nearby activity - stacks of ice per session, with blue ice as the slow-but-free long-term output (81 ice per block).
Tips
- Water needs direct sky above it and block light below 10 to freeze.
- Keep a water bucket row unfrozen at the edge to refill the pond.
- Blue ice also feeds basalt generators.
- Blue ice does not melt near light sources: use it for bright halls.
