About the Fast Smelt data pack

I made this because I don't like waiting for a lot of items to smelt, especially when I'm out exploring.

With this datapack/mod, smelting on Furnace, Blast Furnace, Smoker, and Campfire takes only 1 game tick per item. This means Blast Furnace and Smoker are pretty much redundant since regular Furnace now smelt just as fast. And it works with all smeltable items.

📝 NOTES

You only need to download one. Choose either the datapack or the mod version, whichever is more convenient for you.

Fabric/Forge/NeoForge mods all in one JAR file. If you use Fabric Loader, the mod also requires Fabric API. And feel free to use it in your modpack.

  • ⚠️ When you load the datapack, it might says "incompatible" but it will still works.
  • ⚠️ Minecraft Snapshot support only works on Fabric Loader.
