Smart Furnaces
by S1xH3arts
With Smart Furnaces installed, the furnace, smoker and blast furnace each show how fast the fuel in them is burning items.
What it does
Smart Furnaces scales smelting speed by burn time, so fuels that burn longer cook more slowly and shorter-burning fuels cook faster. The vanilla smelting process itself is kept, and the adjustment is applied to each furnace type. Common fuels, along with modded fuels, are handled automatically.
Hovering over a furnace shows a real-time panel with the cook time per item, the items each fuel can smelt, a queue of items with the time remaining, and a speed multiplier color-coded by how the fuel compares. The mod is for survival players, adventure maps and servers that want clearer fuel information. It runs on Fabric only, for 1.21.11, and both the server and each player need it. Smart Furnaces is not open source and is licensed under All rights reserved.
The config file is generated on first launch. Server owners can set the speed curve strength, minimum and maximum speed limits, a reference fuel balance and per-fuel overrides. Changes are applied by reloading with a command that only operators can run in the console.
Key features
Fuel-based speed scaling
Smelting speed follows the burn time of the fuel, with better fuels cooking faster and weaker fuels cooking slower.
Hover information panel
Hovering over a furnace shows the cook time per item, the items the fuel can smelt and the time left in the queue.
Color-coded speed multiplier
The multiplier is shown in color so players can compare fuel efficiency at a glance, including items smelted per fuel.
Configurable balance
The speed curve, speed limits, reference fuel and per-fuel overrides are set in a generated config file.
Compatibility
Latest build for each game version and loader.

Furnace ETA hud and FurnaceHUD are client-side only, and Conifgure-Furnace-Speed is a client and server mod for 1.21.2 – 1.21.11 under All rights reserved.
