The Large Smelting Furnace is one of the most important crafting upgrades you can unlock in Windrose. Once you push into tougher biomes and start handling advanced materials, the basic setup stops cutting it. This station handles the heavy lifting for ingot production and opens up gear upgrades that simply aren't possible without it. Here's exactly how to get it built and running.
What do you need to build the Large Smelting Furnace?
Before you can place the furnace, you need to meet a specific progression requirement: discovering the smelting process for Mire metal. According to the source material from patchcrazy.co.uk, this unlock is tied to finding the Blacksmith Bellows and the Jeweller's Table, both of which become available as you explore deeper into the game. Most of the resources connected to this station, including Ancient Scraps, are found in the Cursed Swamps biome.
Once that unlock condition is met, the actual material cost is straightforward:
The build itself is fast once you have the materials gathered. No complicated multi-step construction process here.

Where should you place the Large Smelting Furnace?
Placement matters more than most players expect. Two conditions have to be satisfied at the same time:
- The furnace must be outside the base or under a shelter (not inside enclosed structures)
- It must sit within Bonfire range
If either condition isn't met, the station stays inactive. Plan your base layout before you build so you're not wasting materials repositioning things.
Set up your Bonfire first, then build the Large Smelting Furnace nearby. Working outward from the Bonfire makes it much easier to confirm you're within range before committing to the placement.
What can you craft in the Large Smelting Furnace?
Once the furnace is active, it processes raw resources into four types of output, each tied to different stages of gear progression:
- Copper Ingots
- Essence Arborum
- Foothills Iron Ingots
- Mire Metal Ingots
The Mire Metal Ingots are the main reason you're building this station in the first place. They're the advanced tier material you'll need for stronger equipment once you're deep into the Cursed Swamps content. The other outputs keep earlier crafting needs covered so the furnace stays relevant across multiple progression stages.

How does the Large Smelting Furnace compare to earlier stations?
The furnace sits above basic crafting setups in the progression chain. Its main advantage is access to Mire Metal Ingots, which earlier stations can't process. The tradeoff is the placement restriction: unlike simpler stations, this one needs outdoor positioning and Bonfire proximity, which requires more deliberate base planning.
