Build 42 reference · Not current-build play-tested
Sources checked 11 September 2026 against Stable 42.20.4: Pype’s vanilla-definition page and PZFans’ current overhaul agree on the starter pile, wood batches, and charcoal fuel use; Steam players corroborate the pile interaction, but no new-character play-through was tested. PZwiki’s Charcoal Burning Pile page is scoped to 42.12.3 and its Charcoal item page to 42.3.1, where an old five-log Metal Drum recipe conflicts with the current pile route, so use the installed craft row.
Build the charcoal station, not a regular fireplace
Read Magazine: Iron Age Blacksmithing, then use a dig-grave tool to build the Charcoal Burning Pile. The tool tag includes shovel-class options such as an Entrenching Tool, Spade, Wooden Spade, or Shovel. The station itself has no consumed construction material in the current starter definition.
The wiki/source key may call this a Charcoal Burning Pit, but the player-facing station is the pile/burning-pile entry shown by your build. A normal fireplace or campfire is not the charcoal recipe described here.
Load one of the verified wood batches
Open the pile’s workstation UI and use one of these direct batches:
- 2 Logs → 12 Wood Charcoal
- 3 Large Branches → 12 Wood Charcoal
- 6 Planks → 12 Wood Charcoal
These alternatives let you use the wood form you already have. Do not add a random mixture and assume it will satisfy the recipe; use the exact input row the craft panel enables.
Choose Burn Wood into Charcoal and collect the output
- Left-click the completed pile to open its UI.
- Select Burn Wood into Charcoal for the batch you have.
- Wait for the craft to finish, then move the Wood Charcoal output into a safe container.
- Repeat before a forge session so the fuel is staged beside the furnace.
The output is the useful checkpoint: 12 Wood Charcoal from one verified batch. You are not trying to light the wood in a household fire and sift the ashes afterward.
Carry the charcoal tag into a furnace or forge
For the first blacksmithing product, the Primitive Furnace accepts 8 charcoal-tag fuel with 1 Iron Ore for Extract Iron Bloom. A Primitive Forge bloom-to-iron step uses 4 charcoal-tag fuel. The tag is why Wood Charcoal works even though the item name is not simply “Charcoal”; use the recipe row’s accepted items rather than guessing from the label.
Keep enough fuel for the whole conversion. A furnace that accepts the recipe but has too little tagged fuel is a staging problem, not evidence that the pile failed.
If the pile or recipe does not appear
- Check that Iron Age Blacksmithing was read and that you are in the building/workstation path.
- Check the digging tool’s condition and whether it carries the dig-grave tag.
- Check the wood form and quantity against the enabled recipe row.
- Check the output inventory and the charcoal tag at the destination furnace.
Do not fall back to the older “five logs in a Metal Drum” advice without checking its source version. Later charcoal burners or a Dome Kiln may have different unlocks and inputs; this page keeps the first, independently corroborated pile route usable.
