The Primitive Furnace is a small clay and stone furnace for smelting iron items. It is the first furnace in Blacksmithing and the entry point to making metal.

It handles the simplest smelting jobs. Iron Ore becomes an Iron Bloom, scrap iron becomes Iron Chunk, and Copper Ore becomes Copper Scrap. Casting bars and ingots, the Blacksmith Anvil and glass belong to the furnaces above it. A survivor builds this one first, then moves up to the Smelting Furnace and later the Blast Furnace. It is built on site from clay, stone and concrete.

How to Build Primitive Furnace

The build recipe is Construct Primitive Furnace, listed under Blacksmithing in the build menu. It takes six Clay, four Stone and one bag of concrete.

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 Primitive Furnace recipe is in the Blacksmithing build menu. It needs no skill level.

How to Use Primitive Furnace

Every smelt is a recipe at the furnace, and charcoal goes in as the fuel. Any item that counts as charcoal works. Bigger items burn more charcoal than small ones.

Most recipes also need a Large Ceramic Crucible and tongs. Crude tongs are fine. Both are kept and come back after each smelt. The two ore recipes need only the ore and the charcoal.

Placing the furnace next to the Primitive Forge saves carrying heavy metal back and forth.

Crafting Recipes

Ore comes first for many smiths. Extract Iron Bloom turns Iron Ore into an Iron Bloom. Smelt Copper Ore turns Copper Ore into Copper Scrap.

Scrap is the other main supply. Smelt Iron From Small Item, Smelt Iron From Medium Item, Smelt Iron From Medium Plus Item and Smelt Iron From Large Item melt old iron objects into Iron Chunk. Larger objects give more chunks for more charcoal.

Extract Iron from Smaller Items takes handfuls of small pieces. Nails, Iron Piece, Forged Fork, Forged Spoon, Forged Needle and Forged Fishing Hook all qualify. A batch of them becomes one Iron Chunk.

Every recipe made at the Primitive 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.

Station Tiers

The Smelting Furnace runs every recipe here and adds casting, the Blacksmith Anvil and glass. The Blast Furnace runs all of that and the steel recipes on top.

Stay at the Primitive Furnace while the work is ore and scrap into chunks. Move up once iron bars, ingots or an anvil are needed. The Smelting Furnace takes forty Stone Block and a Mason's Trowel, so gather those first.

The Primitive Furnace shares its recipes with the stations below. A higher station runs everything a lower one runs.
