More Furnaces (Polymer)

Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21.11Newest
Minecraft 1.21.9–1.21.10
Minecraft 1.21.8
Minecraft 1.21.6
Minecraft 1.21.5
Minecraft 1.21.4
Minecraft 1.21.2–1.21.3

⬇ Download for 1.21.11 ⬇ Download for 1.21.9–1.21.10 ⬇ Download for 1.21.8 ⬇ Download for 1.21.6 ⬇ Download for 1.21.5 ⬇ Download for 1.21.4 ⬇ Download for 1.21.2–1.21.3

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Overview

A simple, server-side mod which adds quicker furnaces and upgrades:

Iron Furnace (2x Speed)
Gold Furnace (3x Speed)
Diamond Furnace (4x Speed)
Netherite Furnace (6x Speed)
Speed Furnace Module
- Doubles speed, but increases fuel consumption
Efficiency Furnace Module
- Cuts fuel consumption by half, at the cost of speed

Thanks to Polymer, this mod can be used server-side only.
While it will also work fine on clients, you probably want to use a true port like this one instead.
Make sure to enable Polymer AutoHost on your servers.

Some translations are also available, follow this link to see all supported languages. If you end up adding a language, I would appreciate if you could open an issue or pull request on GitHub, so that it can be made available for everybody.

Please open an issue on the GitHub page if you think you encountered a bug.
