Iron Furnace: Reburn
If you have ever built a sprawling factory in Minecraft and wished your furnaces could do more, Iron Furnace: Reburn is the add-on you have been waiting for. This fork of the classic Iron Furnace project takes everything players loved about the original and pushes it further with a flexible, data-driven furnace system, a reworked Rainbow Furnace, and a cleaner interface. Whether you are a casual builder or a dedicated pack maker, this mod reshapes how you think about smelting in Minecraft.
What Makes Iron Furnace: Reburn Different
Iron Furnace: Reburn is based on version 4.1.6 of the original project, but it does not stop there. It ports bug fixes from versions 4.1.6 through 4.3.2 while keeping full compatibility with the original mod. That means your existing saves and setups remain safe. The familiar furnace progression is still present, but the fork layers on a much more flexible system for custom furnace content, a rewritten UI, and better recipe compatibility for modern modpacks and data packs.
The original 4.1.6 project was released under the GNU General Public License v3.0, and this fork follows that same licensing background, so pack makers can use it with confidence.
Key Features of Iron Furnace: Reburn for Minecraft
Data-Driven Furnace Types and Upgrades
Instead of being locked to a fixed set of built-in furnace tiers, Iron Furnace: Reburn lets developers register their own furnace types and define exactly how they behave. Working speed, energy capacity, energy production, energy consumption, parallel processing count, and upgrade paths can all be configured freely. Every registered furnace and upgrade also appears in JEI, making them easy to discover during normal gameplay.
A More Customizable Rainbow Furnace
The Rainbow Furnace has been expanded into a flexible, configurable system. Alongside the original bonuses tied to existing furnace types, it can now gain different bonuses depending on which furnace types are currently active. These bonuses are data-driven and can be modified through data packs, and both bonus types can be enabled or disabled in the config file. That makes it simple to tune the feature for different packs and balance preferences.
Reworked Furnace Interface
The furnace UI has been rewritten for a cleaner, more practical experience. Side tabs let you manage settings, burn remaining storage, and the augments inventory without digging through menus. Factory mode now shows up to nine slots at once, and furnaces with more slots support page switching so larger inventories stay usable instead of turning into clutter.
Better Recipe Compatibility
Recipe support has improved significantly. Both new and legacy furnaces now support using tags in blasting generate recipes, which helps the mod work smoothly with modded item sets, tag-based recipes, and data pack customization.
Performance-Minded Behavior
The new furnaces are designed to behave more lazily than the old ones, which may improve performance in real use. Under normal play, performance should not be a problem. Issues are only likely to appear in extreme setups where very large numbers of furnaces run at the same time.
Supported Versions and Loaders
Iron Furnace: Reburn is a Forge and NeoForge mod only, and a Fabric version is not planned. Current supported versions are Forge 1.20.1 and NeoForge 1.21.1. The 1.21.1 release will be the last version that keeps compatibility with older content and older systems, since there is no above-1.21.1 support version of the original project. If you want to download Iron Furnace: Reburn, check the version that matches your loader before you start.
For players who prefer a smoother setup, the foxygame.net launcher offers a one-click install for Iron Furnace: Reburn, pulling the correct build for your Minecraft version automatically so you never have to match files by hand.

For Players and Pack Makers
For players, this fork delivers many bug fixes for legacy content. Even if you never touch the new furnace system, you still benefit. If you feel the original mod has become old-fashioned and want more customization, this fork is for you. You do not need to worry that it will break your save, because all code from the original mod remains sound and all new content is separated.
For pack makers and developers, the new data-driven structure makes it far easier to add custom furnace types, define upgrade routes, and tune furnace behavior for a pack. The Rainbow Furnace system is also much more configurable than before, letting it fit a wider range of progression styles.
Conclusion
Iron Furnace: Reburn is more than a simple patch. It is a thoughtful evolution of a beloved mod, blending bug fixes, a rewritten interface, and deep customization options into one package. Whether you are smelting your first stack of iron or designing an entire factory modpack, this add-on gives you the tools to build the furnace system you have always wanted in Minecraft.
