Crystallization is a Fabric mod for Minecraft Java Edition 1.16 through 26.2. While enabled, right-clicking a dry waterloggable block with regular ice waterlogs the target and consumes one ice block.
Usage
The feature is disabled on first launch.
Press Alt + F in game to toggle it. Change the primary key under Options > Controls > Key Binds > Crystallization.
With the matching Mod Menu version installed, use the configuration screen to toggle the feature or open the key-binding screen.
Use vanilla ice on a dry waterloggable block such as a stair, slab, fence, or trapdoor.
The mod and the matching Fabric API must be installed on both the client and server for multiplayer. Mod Menu is optional.
Version support
Minecraft changes mappings, Fabric networking, GUI APIs, Java requirements, and (since 26.1) its obfuscation model across this range. The project therefore builds one JAR per compatibility family instead of declaring one unsafe universal JAR.
