Expanded copper
by Lankaster
Expanded Copper gives copper blocks the same kinds of uses that iron has in vanilla: buttons, a pressure plate, a trapdoor, a door, bars and a lantern.
What it does
Each new block keeps the behavior of its vanilla counterpart while changing its material. The copper button, pressure plate, trapdoor, door and bars all oxidize over time, like other copper blocks in the game. The copper button has oxidizable variants with custom durations, and the copper pressure plate only reacts to dropped items, not to players or mobs. The copper lantern serves as a light source and comes with copper chains, which suits mineshafts and other underground structures.
The mod is built to stay close to vanilla mechanics rather than reshape the game, so its blocks behave as players already expect. It runs on Fabric and needs to be installed on both the client and the server. The source code is public, and the code is released under the CC0 1.0 Universal license, which places it in the public domain. Create: Chains from Copper depends on this mod's content, so Expanded Copper is required by it.
Key features
Copper button
A copper button that oxidizes over time, with oxidizable variants that use custom durations.
Copper pressure plate
A pressure plate that only detects dropped items, so it is a precise trigger for item-based circuits.
Copper trapdoor and door
Decorative copper versions of the iron trapdoor and iron door, both of which oxidize like other copper blocks.
Copper bars and lantern
Oxidizable copper bars give a steampunk look, and a copper lantern with copper chains lights up underground spaces.

How it compares
Redstone Bits is a Fabric mod for 1.18 – 1.20.3 that is open source under the GNU Lesser General Public License v3.0 only, and it runs on client and server. Expanded Copper uses the CC0 1.0 Universal license, which is also open source, and it is published for Fabric only. Oxidized is a Fabric mod for 1.19.2 – 1.21.1, open source under the GNU General Public License v3.0 only, that runs on client and server, so it reaches later versions than this mod.
