The Metallurgic Furnace is the hottest smelting construction, with a max temperature of 6 — above the Furnace (temp 5) and Bloomery (temp 4). That extra heat is what lets it smelt the high-temperature alloys — Dziwer and Bulat — that the lower stations can't reach. For the wider refining chain, see Smelting.
Like the other furnaces it runs semi-AFK: load fuel and materials, fire it with the bellows, and come back now and then to keep the heat up.
What it smelts
The Metallurgic Furnace's headline outputs are the top-tier metals:
- Dziwer Bar
- Bulat Bar
Bring coal
The hottest recipes — like the Bulat Bar — need the ceiling only Coal (max temp 6) provides; billets (4) and charcoal (5) won't get there. The furnace only gets as hot as both its own cap and the fuel you feed it allow.
Running it
- Place the furnace — it can go nearly anywhere, ideally in a [Crafting District](/wiki/crafting-guides/destroying-workstations).
- Load the materials you want to smelt.
- Add fuel — Coal for the hottest recipes.
- Click the bellows to start and bring the heat up to the recipe's temperature.
- Check back every few minutes to top up the heat, since it decays.
Placement, decay & safety
- A [Crafting District](/wiki/crafting-guides/destroying-workstations) or a loot zone grants a production-speed bonus; the screen only shows the placement bonus, but Smelting and Roasting tree bonuses still apply.
- In a loot-enabled area it can be 100% emptied by enemy nation players — your own nation can never loot it.
- At a guild province the guild leader can destroy it; see Smelting for the full looting and best-practice rules.
- It decays after 5 days without interaction, returning its contents to the "My Offers" tab of The Market.
