Copper Age Backport
(formerly Copper Golem Legacy)
A Minecraft mod that brings the complete Copper Age experience to older Minecraft versions. Starting with the beloved Copper Golem from the Minecraft Live 2021 mob vote, this mod adds copper-related blocks, items, and mechanics, including Copper Chests, Buttons, Statues, and the full oxidation system.
