Chislate
by DarkFish
Chislate ports copper blocks, decorations and utility items from later Minecraft versions back to 1.20.1 for Forge players.
What it does
The mod brings copper-themed content from later Minecraft updates into 1.20.1, including new copper variants, oxidation mechanics, decorative blocks and utility items. The content is recreated to match the original Copper Age additions, so players on 1.20.1 can use copper features that newer versions introduced.
Chislate runs on client and server, so both the server and every player need the mod installed. It is published for Forge only, with a single build for 1.20.1, and the latest file is 1.20.1-0.2.3-beta, released on the beta channel. The code is released under the MIT License, but the project is not open source.
Key features
Oxidation mechanics
Copper blocks weather over time through oxidation stages, matching the behavior of the newer copper content.
New copper variants
Additional copper block variants are added so builders can mix textures and tones within one project.
Decorative blocks
Copper decorations such as trim and ornamental pieces extend the palette for building interiors and exteriors.
Utility items
Copper tools and utility items are ported alongside the blocks, keeping the set consistent with the original update.

Who it’s for: The mod suits players and server owners who stay on Minecraft 1.20.1 and want the copper content added in later updates. It requires Forge and works with a single game version.
