In vanilla Minecraft, copper oxidizes on its own — but it takes forever. This plugin lets you fast-forward the process: dip a copper block into a water cauldron and instantly receive the next oxidation stage.
Supports all stages and all types of copper blocks: normal → exposed → weathered → oxidized. Waxed and fully oxidized copper are ignored — just like you'd expect from game logic.
Features:
- Supports all copper block types and slabs
- Full four-stage oxidation chain
- Waxed blocks are ignored (prevents accidental use)
- Cauldron loses one water level per use
- Smoke particles and sound effects
