Carbonised
by Fisch37
Carbonised changes how fast copper blocks oxidise, based on how much of each block is exposed to air and water.
What it does
Copper blocks oxidise at a rate set by their neighbours: a block surrounded on more sides by other blocks oxidises more slowly, while one with fewer sides exposed to air or water has fewer random ticks turned into oxidisation attempts. A copper block surrounded on two sides by water oxidises faster underwater, and a fully submerged block behaves the same as one floating in air.
Blocks that are completely surrounded still become oxidised, because the attempt passes through neighbouring copper blocks. Batches of copper blocks balance their oxidisation levels without cancelling each other's attempts. The final oxidisation chance is capped at 1 due to a technical limitation.
Carbonised is a server-side mod: only the server needs it, and players join without installing anything. It is published for Fabric alone, with four game versions, 1.21, 1.21.1, 1.21.4 and 1.21.5, and Fabric API is required. The code is open source under the MIT License.
Key features
Neighbour-based oxidisation speed
The chance a copper block oxidises depends on how many sides touch other blocks, air or water.
Faster oxidisation underwater
Copper blocks with two sides touching water oxidise faster, and a submerged block matches one in open air.
Batch balancing
Groups of copper blocks even out their oxidisation levels without cancelling oxidisation attempts.
Capped chance
The final oxidisation chance cannot exceed 1, so a block in a fully exposed position oxidises at most once per attempt.

Use cases
Copper builds on servers
Server owners can set copper roofs and statues to age realistically on multiplayer worlds, since only the server runs the mod.
Who it’s for: Server owners and builders who keep copper structures on survival worlds and want their oxidisation to depend on where each block sits.
How it compares
The Copper Beacon is a client and server mod under the MIT License, published for 1.21 only. AutoOxidize is client-side only under the MIT License and covers 1.21 – 1.21.5, so it runs on the player side rather than the server. Quicker Copper is server-side only and open source under the Apache License 2.0, but it is published for 1.20.4 – 1.21.11.

What the author says
However! The fewer sides of a copper block are exposed to air or water, the fewer random ticks will be turned into oxidisation attempts. Blocks that are completely surrounded will not attempt to oxidise, but can still become oxidised through other copper blocks. For every side of a copper block that is surrounded by…
