RustedIron
by firenh
RustedIron lets iron blocks rust over time when placed in the world, the way copper oxidizes, with four visible stages.
What it does
Placed iron blocks pass through four rust stages, Unaffected, Exposed, Weathered and Rusted, following the same pattern copper uses. The mod also adds new iron building blocks, including slabs and stair variants, so rusted and unrusted iron can be mixed in builds.
Axes scrape rust off one stage at a time, and wax keeps a block from rusting further. Waxed blocks can be turned back into nine iron ingots through crafting. Shader support has been adjusted so rusted iron textures show appropriate shininess under shaders such as SEUS PTGI.
RustedIron is built for Fabric 1.18.1 and uses the Fabric Toolchain. Only the client needs nothing extra, because the environment is client and server, so the server and every player need the mod. It is released under the GNU Lesser General Public License v3.0 only and is open source, with public source code and an issue tracker.
Key features
Four rust stages
Iron blocks change through Unaffected, Exposed, Weathered and Rusted stages after they are placed in the world.
Iron slabs and stairs
New slab and stair variants in iron give builders more shapes that take on the same rust stages.
Axe scraping and wax
Axes remove one rust layer at a time, and wax stops any further rusting on a block.
Crafting back to ingots
A crafting recipe turns a waxed iron block back into nine iron ingots.
Shader-friendly textures
Rusted iron textures carry shininess settings so shaders such as SEUS PTGI render them differently from fresh iron.

Use cases
Who it’s for: RustedIron suits builders who want iron to age visibly in survival or creative worlds, and players who use shaders and want rust to look right under them.
How it compares
Metal Stairs and Vertical Slab are both Fabric mods for 1.18.2, open source and published under CC0 1.0 Universal, so they add shapes without rusting. MoreLogBlocks covers 1.17 – 1.18.2 under the GNU Lesser General Public License v3.0 only, adding log variants rather than metal blocks.

What the author says
A Minecraft Mod built on the Fabric Toolchain for Minecraft 1.18.1 to add in the ability for iron blocks placed in the world to rust. Also adds in new slabs and stair variants for iron! Pretty simple mod overall. Iron rusts in four stages just like copper, with the stages being known internally as Unaffected…
