Large Furnace

The Large Furnace is used for smelting larger quantities of ore, faster than a regular furnace. The ores that can be smelted using a Large Furnace are: Metal Ore, Sulfur Ore and High Quality Metal Ore. Wood is used as the fuel for smelting and the Large Furnace holds 2 stacks of wood for up to 2000 total. There are 5 slots for raw materials so a total of 5000 ore can be smelted at once. There are 5 output slots which will fill with your finished product and charcoal. The Large Furnace must be placed on terrain and takes up 4 square foundations space. The Large Furnace cannot be placed on foundations or floors.

Useful for stacking more ore's for quicker cooking time.

You have to place this on the dirt/sand/snow etc, but you still need to protect it! Place wood/stone walls/gates around it, so other players cant loot it without raiding you!

Zach 49 pts. 3 years ago

If you plan on logging off for a while, you might want to put two stacks of fuel and leave four empty slots for charcoal and smelted ore. This is less efficient as it uses more wood for less ore output, however it allows for more ore to smelt without player intervention.

There are few bigger raid magnets than a large furnace. If you're a solo player, you're better off using your neighbor's large furnace (with or without their permission) than building your own and drawing unwanted attention.

600 metal ore = 200 wood, 300 sulfur ore = 50 wood

Nkolik 11 pts. 6 years ago

Spread out your ores in it. You still need 3 slots. 1 Slot for putting the wood in. Another slot for the coal. And for the last spot, your smelted ore. What this will do it would make the cooking time more faster.

GavinGWhiz 11 pts. 3 months ago

A simple automation cycle with conveyors sending your ore out (along with wood) can be done relatively cheaply (both in scrap research and resources) in T2. With some storage adapters, conveyors, and piping to a box inside your base, you can ensure that anyone walking by can only steal the wood and unsmelted ore. All refined material will get immediately conveyed back inside.
So stealthy raiders can sit there and siphon off your unsmelted ore + wood, but they'll still have to work to smelt it. They're less likely to fill up inventory slots with 'raw' materials like that than try and find good loot elsewhere.
Rust is about making life harder for raiders, not magically stopping them from ever taking something. Automated large furnaces early-game (e.g. if you find one in a crate while still in T1 research) can put you into full sheet metal base faster than anyone else.
