🧱 Heavy Metals: Industrial Refinement
Tired of the furnace clutter?
We’ve all been there: coming back from a mining trip with stacks of raw iron, only to realize you need to build a literal wall of furnaces just to smelt it all before next week.
Heavy Metals solves the logistics nightmare without breaking the game's balance.
💎 Why use this?
- One Slot, Nine Items: Smelt a whole Raw Iron/Gold/Copper Block in a single furnace slot.
- Compact Bases: Reduce your "furnace room" size by 90%.
- Vanilla Logic: No magic, no cheats. It takes the same time and gives the same XP as 9 individual ingots ($1800$ ticks).
🛠️ How it works:
- Craft your Raw Ores into Raw Blocks (9 ingots block).
- Toss the raw block into Furnace
- Get a solid metal block back!
