We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: End of Week.
Ice farming is the process of controllably, and renewably, generating ice in order to gather it with a Silk Touch pickaxe. Ice can be found naturally in icy biomes but an ice farm can make it much easier to collect in large quantities.
Configuration[edit | edit source]
An ice farm consists of a large flat pan, open to the sky in an icy biome, which contains an infinite water source. Two diagonally adjacent walls will have outgrowths protecting strategic water blocks from freezing, causing a fully mined-out farm to refill with fresh water source blocks. Using light sources to protect these blocks is not recommended, due to the melt/refreeze cycle this would cause. An ice farm's footprint is 3 layers deep, and however large you want the ice layer to be plus 3x3. The configuration for a 3x3 farm is shown below.
Take care not to allow trees or other obstacles to overhang the farm, and keep light sources at a distance, otherwise some or all of the farm's area will not freeze.
Use[edit | edit source]
An ice farm is harvested by standing in the ice pan and mining more or less indiscriminately with a Silk Touch pickaxe. The ice blocks will be harvested, while the water source blocks at the rim and (hopefully) the dirt bed will be unaffected. The water blocks will then spread to refill the farm, and you simply wade around to collect the harvested ice.
Other Harvesting Methods[edit | edit source]
Ice could theoretically be generated in the same way as cobblestone using two water source blocks, even to the extent that it could be piston-driven and used to build self-repairing structures. However, ice freezes slowly enough that an absurdly long clock cycle or a BUD (Block Update Detector) would be needed. Either way it would serve as a very impractical toy.
Spleef[edit | edit source]
A large ice farm can double as a self-resetting spleef arena. Not using Silk Touch tools creates a variant where the broken blocks might reform during play. Using Silk Touch creates a more conventional game, and also harvests the ice. In this case, the arena will not reset properly until all the ice is mined, or perhaps melted with a grid of redstone lamps. A farm used for spleef should probably cover its water sources with an unbroken protective lip rather than alternating blocks, as they might snag players otherwise.
An ice farm can also be used as an ordinary skating rink.
