Copper++
by SpidX_9226
Copper++ extends copper with new tools, nuggets and ingots, and with oxidation variants for each of its items, for NeoForge in 1.21.5 – 1.21.6.
What it does
Copper++ adds copper tools and copper nuggets, along with oxidized tool variants that follow the same oxidation stages as vanilla copper blocks. Oxidized copper ingots are also included, so the oxidation path extends beyond blocks to the items a player carries.
Oxidation can be sped up by throwing items or blocks into a cauldron filled with water. The mod also offers waxing for 128 block types, which stops oxidation on blocks that should stay in their current state. Several oxidation states beyond the vanilla four are part of the design. Servers that run it need every player to install it too. It is published for NeoForge only, for 1.21.5 and 1.21.6, under the Apache License 2.0, and the source code and issue tracker are public. The mod requires Iron Lapis Required Copper Tools, which must be installed alongside it.
