    About

    Iron Furnaces expands on the vanilla furnace with an upgradeable range of faster furnaces, from Copper, Iron, Silver, Gold, Diamond, Emerald, Crystal, Obsidian, and Netherite through the Rainbow Furnace; Allthemodium, Vibranium, and Unobtanium tiers are also available when the Allthemodium mod is installed. Upgrade paths let furnaces progress through tiers, with higher tiers cooking faster and some handling multiple items at once; for example, the Netherite Furnace processes four items per second, while the Rainbow Furnace processes 64. Augments adapt furnaces for different jobs: Blasting and Smoking speed up the corresponding restricted recipe types, Speed doubles cooking speed at twice the fuel use, Fuel Efficiency trades slower cooking for lower fuel consumption, and Factory adds processing slots. Other options include turning a furnace into a generator that produces energy from fuel, or using linked Wireless Heat Transmitters and Receivers to provide furnace heat using FE. The Rainbow Furnace has a distinctive linked-furnace bonus: connecting it to all other furnaces as generators with a Rainbow Linker adds 50 kRF per tick of energy generation.

    In-game changes

    Does not change the game's code directly.

    Adds 14 blocks, 30 items, 58 recipes and 1 advancement.

    Counted from the names and data files in the mod, so the list may not be complete.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Forge 1.20 to 1.20.6. See Privacy

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 22 latest files checked, last on 15 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      22 latest files: the newest file for each Minecraft version and loader. The answer above is about the 4 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends about you

    We read its code without running it: it contacts 1 web address while you play.

    Like any connection, each address it contacts sees your IP address.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · All 4 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of all 4 files, for recent Minecraft versions. See each file in Releases
    • raw.githubusercontent.com
      Checks for a new version of the mod.
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images, code history and pull requests and found none.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.

    How we checked · 8 places read
    • Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.
