The Smelting Furnace is a stone furnace for smelting iron and turning sand into glass. The game describes it as a furnace for smelting iron items or turning sand into glass.
It is the middle furnace of Blacksmithing and the first furnace for Glassmaking. It runs every recipe of the Primitive Furnace. It adds casting molten iron into bars and ingots, and it casts the Blacksmith Anvil. The anvil is what a Simple Forge or Advanced Forge needs, so this furnace opens the way to real forging. A survivor usually starts at a Primitive Furnace and moves here once casting is needed. The Blast Furnace comes after it for steel. The survivor builds it from stone blocks.
How to Build Smelting Furnace
The build recipe is Construct Smelting Furnace, listed under Blacksmithing in the build menu. It takes forty Stone Block and one bag of concrete. A Mason's Trowel is needed and is kept.
The recipe is known from the start. The Blacksmith occupation, the Blacksmith Knowledge trait and the Mason trait all start with it known.
The finished furnace has 150 health. Each point of the builder's skill adds 50 more.
The Construct Smelting Furnace recipe is in the Blacksmithing build menu. It needs no skill level.

How to Use Smelting Furnace
Every craft at the furnace takes charcoal as its fuel input. Any item that counts as charcoal works. Glass recipes also need a fire starter.
Molten metal is handled in ceramic crucibles. Smelting scrap fills a Large Ceramic Crucible or Small Ceramic Crucible with iron or steel. Casting then pours those filled crucibles into a mold. Tongs are needed for nearly every recipe, and crude tongs work for most. The Cast Blacksmith Anvil recipe needs proper tongs.
The tongs and the bar or ingot molds are kept after every use. The crucibles come from a kiln, fired from clay shaped at the Pottery Wheel.
Crafting Recipes
The basic smelting matches the Primitive Furnace. Extract Iron Bloom works ore into an Iron Bloom. Smelt Copper Ore gives Copper Scrap. The Smelt Iron From Small Item group turns old iron into Iron Chunk.
Crucible work is new here. Extract Iron from Iron Ore fills a Large Ceramic Crucible with Iron from ore or a bloom. Smelt Small Iron Item, Smelt Medium Iron Item, Smelt Medium Plus Iron Item and Smelt Large Iron Item melt scrap into crucibles of iron. Smelt Smaller Iron Item does the same with handfuls of nails and small forged pieces. Smelt Large Steel Item melts big steel objects into a crucible of steel.
Casting turns those crucibles into stock. Cast Iron Bar makes an Iron Bar, and Cast Iron Ingot makes the larger Iron Ingot. Cast Blacksmith Anvil pours a great deal of iron into a Ceramic Blacksmith Anvil Mold to make the Blacksmith Anvil.
For glass, Melt Glass takes Broken Glass and Melt Sand takes a Sack of Sand. Both give a Small Ceramic Crucible with Molten Glass.
Every recipe made at the Smelting Furnace is listed with what it uses up, the tools it hands back and the skill it asks for. A "Yes" under Learned means the recipe has to be learned before it shows up. Each tab holds one crafting menu category.

Station Tiers
The Primitive Furnace runs only the simplest ore and scrap smelting. The Smelting Furnace adds casting, the anvil and glass. The Blast Furnace runs all of this plus the steel recipes.
The Blast Furnace costs the same stone and concrete plus a Large Bellows. Move up when steel bars, steel ingots or steel chunks are needed.
The Smelting Furnace shares its recipes with the stations below. A higher station runs everything a lower one runs.

Notes
- The build tooltip reads: for smelting iron items or turning sand into glass.
- This is the lowest furnace that can cast the Blacksmith Anvil for a forge.
- The anvil mold must be fired in the Large Kiln first.
- Molds and tongs are kept, so cast iron in batches.
- Glass work starts here with a Small Ceramic Crucible and some charcoal.
