The Furnace is a workstation construction used to smelt low to mid-temperature ores such as Iron Lump and Steel Bar. It has a max temperature of 5 — a step above the Bloomery (temp 4), and below the Metallurgic Furnace (temp 6) used for the hottest work. For the wider refining chain, see Smelting.
Furnaces can be filled with materials and left to smelt in a semi-AFK manner. The heat level decreases over time and must be maintained, so you'll have to come back every few minutes to manage it.

Running the furnace
- Place the furnace — it can go nearly anywhere in the world.
- Load the materials you want to smelt into the material slots.
- Add fuel — wooden billets, charcoal or coal — to the fuel slots above.
- Click the bellows button to start processing and bring the heat up to the recipe's required temperature.
- Check back every few minutes to top up the heat, since it decays over time.
Fuel & heat
The fuels burn to different ceilings — wood billets are coolest, charcoal hotter, and coal the hottest. The furnace caps at temperature 5, so it runs the same low-temperature recipes a Bloomery can, plus mid-temperature work the bloomery can't reach — bring coal when a recipe needs its full heat.
What it smelts
The furnace's headline outputs are Iron Lump and Steel Bar — the backbone of every metal trade. Both use the same recipes covered in the Bloomery guide, so see there for their ingredients; the furnace just smelts them faster and unlocks the hotter recipes above a bloomery's reach.
Placement bonuses
Where you set the furnace down matters. Placing it in a Crafting District — the flat, fenced-off areas found in most nation locations and every capital city — or in a loot zone grants a speed-production bonus.
The workstation screen only shows the speed bonus from your placement location. Bonuses from leveling the Smelting and Roasting tree still apply automatically, even though they aren't displayed there.
Decay & safety
- If placed in a loot-enabled area, a furnace can be 100% emptied by enemy nation players — your own nation can never loot it. Don't leave large amounts inside in a loot zone; see Smelting for full looting best practices.
- If placed in a guild province, the guild leader of that province can destroy it.
- It will decay after 5 days if the owner does not interact with it.
- When a furnace decays, the materials inside are returned to you — find them in the "My Offers" tab of The Market.
