Stack Furnace
by short2
Stack Furnace lets players place several furnaces at once and link them into a stack that shares fuel, speed and output upgrades.
What it does
Furnaces can be placed one after another in a row, and each placement shows a message in the toolbar as an upgrade is applied. Holding Shift while placing inserts more than one furnace at a time. The stacked structure grows in multiplier and fuel efficiency as more furnaces are added, with the largest stages needing 65 furnaces for maximum time reduction, 6,464 for the maximum multiplier increase and 12,800,000 for the maximum fuel usage reduction.
The Auto Input Fuel mode takes fuel from the items already used as fuel, which only matters when a hopper feeds the furnace. Lava can be supplied through a Stacked Amethyst Tank, which a redstone signal activates so the liquid moves into the adjacent block. Stackstone Tools and the Stack Transporter are crafted from stone and move stacked furnaces around. Forge is the only loader, and the mod is for 1.20.1.
Key features
Stackable furnaces
Furnaces placed in a row join into a stack, and each step of the upgrade is shown in the toolbar.
Bulk placement
Holding Shift while placing inserts more than one furnace with a single action.
Auto Input Fuel mode
This mode reuses the items used as fuel, so a hopper-fed furnace needs no separate fuel supply.
Stacked Amethyst Tank
A lava tank built from stacked amethyst that a redstone signal activates to feed the block in front.

Use cases
Hopper-fed smelting
Stacks suit an automated line where hoppers deliver items to a row of furnaces, with Auto Input Fuel mode supplying the fuel.
Moving stacks
Stackstone Tools and the Stack Transporter help relocate stacked furnaces without breaking them down one by one.
Who it’s for: Players who want large smelting setups on Forge for 1.20.1 and are willing to build toward the stage thresholds. Server owners need the mod on the server and on each player's client.

What the author says
Hello player, I'm glad you're interested in my mod. This is a creation I made because I really wanted an overpowered furnace mod, so here it is! This mod, as incredible as it may not seem, goes beyond just a furnace. I have a path I want to follow but without spoilers.
