Create: Patina

Create: Patina is an addon for the Create mod that introduces oxidized variants of copper items and blocks, along with mechanisms that drive oxidation. Blocks advance to the next weathering stage when they are submerged in water in a filling process, and bulk washing can be done the same way. Waxing uses honey filled into blocks or a fan carrying honey fluid, while unwaxing and scraping are handled by a deployer holding an axe or sandpaper. Rough rose quartz can be polished. A Patina Clock is assembled through a sequenced assembly, where a deployer installs a precision mechanism, a copper sheet and a honeycomb clock.

The addon covers the vanilla copper blocks as well as the copper blocks of Create, so weathering applies to both. Each stage has an unaffected, exposed, weathered and oxidized variant, with waxed counterparts for every stage. Eight item tags group copper parts by their exact stage, and the seven-variant Create blocks that contain copper components follow the same progression. Create: Patina requires Create, and it is published for Forge and NeoForge for 1.20.1 and 1.21.1. Its code is under the MIT License, but it is not open source.
