Description

🔥 Fast smelting: a whole stack in the time of ONE item 🔥

Tired of waiting 10 minutes for 64 iron?
With Stack Processing, your furnace smelts the entire stack at once, and you still pay exactly the same fuel as vanilla. Faster, not cheaper. Fair for survival and multiplayer.

⚡ Vanilla vs Stack Processing

64 raw iron + 64 coal Vanilla Stack Processing
Time ⏳ 10 min 40 s ✅ 10 seconds
Coal used 8 8 (exactly the same)
Ingots 64 64
XP full full

✨ Features

  • 🧱 Whole-stack processing for the Furnace, Blast Furnace and Smoker: every item finishes in the time of one.
  • ⛽ Fair fuel: you pay the fuel of every item smelted, no more, no less.
  • 🪫 Smart with low fuel: 64 raw iron + 3 coal → 24 ingots; the rest waits in the input.
  • ♻️ Zero waste: fuel is only charged when the batch finishes. Take items out halfway and you keep everything, and leftover burn time is saved for the next batch.
  • 🔥 Live GUI: the flame and progress arrow show the batch working.
  • ⚙️ Works with tech mods (see below) and with modded furnaces that use vanilla logic.
  • 🖥️ Server friendly: per-world config, tested on dedicated servers.

❓ FAQ

Is it overpowered?
It saves time, not resources. Every item still costs its full fuel or energy. Server owners can limit it with maxBatchSize.

Client, server or both?
Install it on both.

Can I use it in my modpack?
Yes! It's MIT licensed, so feel free to include it.

Forge or Fabric?
NeoForge 1.21.1 for now. Other versions depend on demand, so let me know in the comments.
