How to Build a Forge in Project Zomboid — Build 42 Blacksmithing Progression
Build 42 forge progression: Primitive to Simple to Advanced Forge, the crucible-to-anvil prerequisite chain, charcoal fuel, and which material lists conflict.

⚠️ Content Pending Full Verification
Workstation tiers and recipe inheritance come from the community wiki (page stamped 42.12.3 — older than current 42.20.4). Exact material counts conflict between two pages of the same field-tested guide; both lists are shown, neither is asserted.
The Forge Ladder Cross-Verified
Build 42’s blacksmithing workstations form a strict chain, each tier inheriting the tier below:
| Tier | Gating (community-reported) | Notes |
|---|---|---|
| Primitive Forge | No level requirement per build42guide | Your first smelting point |
| Simple Forge | Requires the book Modern Blacksmithing at Home | The “real” forge tier |
| Advanced Forge | Simple’s list + bellows | Inherits all lower recipes |
| Grinder / Kiln | side workstations | Stone wheel line; crucible firing |
Iron flow runs ExtractIronFromBloom → ForgeBar → blades — you start from bloom/sponge iron, not ore-in-one-step.
The Anvil Gate (Why Pottery Comes First) Cross-Verified
Three independent guides agree on the prerequisite chain: mix clay and sand into crucibles (two large or four small), fire them in a kiln, melt iron, and cast the anvil — then the forge’s build list stops being theoretical. The masonry side (stone anvil needs Masonry 2, stone blocks feed the build) is the other pre-forgeskill tax. This chain is consistent across all three sources, which is why we print it despite the material-table conflict below.
The Material-List Conflict Deep-Tested
The same guide site publishes two build lists:
| Source page | Primitive | Simple |
|---|---|---|
| build42guide blacksmithing page | 10 stones + 1 stone anvil + 1 concrete | 30 stone blocks + blacksmith anvil + large pot + log + concrete (+ bellows for Advanced) |
| build42guide recipes page | furnace-style chain: 6 clay lumps + 4 stones + concrete bucket | 40 stone blocks + cement, forge = furnace + anvil combo |
For the skill XP math that drives this line, the skill XP table lists steel-plate (45 XP, level 4) and the charcoal fuel economy; the full tool list and reforging loop live in the blacksmithing guide, and the knapping and masonry pages cover the stone-age side of the chain.
