Moonlight Peaks: How To Get The Furnace Blueprint
The Furnace in Moonlight Peaks becomes important the moment a quest asks for Copper Bars, but the game can make that step feel broken if you already have Copper Ore and Refined Stone sitting in your bag without the blueprint needed to build the machine. The short version is that the Furnace is part of the early crafting progression, and if A Croak and a Crest is asking for Copper Bars before the blueprint has appeared, you may need to let the mailbox and quest timing catch up rather than keep searching the crafting menu for something that has not been delivered yet.
How To Get The Furnace In Moonlight Peaks
To get the Furnace in Moonlight Peaks, keep progressing the early main quests until the Furnace blueprint is added to your crafting options, then build it with 15 Copper Ore and 5 Refined Stone. The Furnace is the machine that lets you turn ore into metal bars, including Copper Bars, which are needed for tool upgrades, crafting routes, and early story progression.
The confusing part is that some players can reach the stage where A Croak and a Crest asks for Copper Bars before they clearly remember receiving the Furnace blueprint. Based on current player reports and what we can tell from our first playthrough, the blueprint may arrive through the mail from the carpenter around the early first stretch of the game, with one player specifically reporting it around Day 10 after another player was stuck on Day 8. If you are on that same timeline, the fix may simply be to keep doing other tasks, sleep through another night or two, and check the mailbox before assuming the quest has softlocked.
Why You Need The Furnace
The Furnace is required because Copper Ore is not the same thing as a Copper Bar. Moonlight Peaks uses the Furnace to process raw ore into bars, and Copper Bars are what the game actually wants for major early progression, including tool upgrades and certain crafting steps. If a quest tells you to make or bring a Copper Bar, carrying raw Copper Ore will not satisfy it.
This is where a lot of early confusion comes from. You can have all the Copper Ore in the world, you can have the Refined Stone ready, and you can still be stuck if the Furnace blueprint has not appeared in your crafting list yet. The missing piece is not more mining; it is access to the machine that turns the mining trip into something the quest system recognizes.
| Material / Machine | What It Does | Why It Matters |
|---|---|---|
| Copper Ore | Raw mining material found in the Cave of Echoes. | Needed to build the Furnace and smelt Copper Bars. |
| Refined Stone | Processed stone material made through early crafting. | Part of the Furnace build cost. |
| Charcoal | Fuel material made from wood in the Furnace. | Required for smelting Copper Bars. |
| Furnace | Processing machine for ore, bars, glass, and charcoal. | Turns Copper Ore into Copper Bars so quests and upgrades can continue. |
Furnace Recipe
The Furnace recipe requires 15 Copper Ore and 5 Refined Stone. Once the blueprint is available, open your crafting menu, build the Furnace, and place it somewhere on your farm where you can access it easily. You will use it often enough that hiding it in some awkward corner just makes every future bar recipe slightly more annoying.
| Item | Recipe | Use |
|---|---|---|
| Furnace | 15 Copper Ore and 5 Refined Stone | Used to make Charcoal, Copper Bars, Iron Bars, Gold Bars, and other processed materials. |
| Copper Bar | 4 Copper Ore and 1 Charcoal | Used for quests, tool upgrades, and early crafting progression. |
If you still need Copper Ore for the Furnace itself, the Moonlight Peaks Copper guide covers the Cave of Echoes route, the Misty Shores unlock, and how to turn your first mining trips into actual Copper Bars instead of a pile of raw ore sitting around doing nothing useful.
How To Get Copper Ore For The Furnace
Copper Ore comes from the Cave of Echoes in Misty Shores, which opens after you progress through Orlock and Fiona’s cursed bridge route. Farm rocks are not the answer here, even if they look like they should eventually cough up something more interesting than Stone. The Copper route is tied to the mine, not the clutter around your starting farm.
Once you can reach the Cave of Echoes, look for ore nodes with orange-brown copper visible on the rock. Larger copper deposits are especially worth breaking because they give more value for the time and energy spent. You need 15 Copper Ore just to build the Furnace, then more Copper Ore afterward because each Copper Bar costs 4 Copper Ore, so it is better to mine with a target number in mind instead of leaving the cave the moment the first few pieces land in your inventory.
How To Get Refined Stone For The Furnace
Refined Stone is made from Stone through your early processing setup, and you need 5 Refined Stone to build the Furnace. If you have been ignoring regular rocks because you are focused on Copper Ore, this is where the game punishes that tunnel vision a little, since the Furnace needs both the metal route and the stone-processing route before it can be built.
The easiest habit is to break some normal rocks during your resource nights rather than only chasing Copper nodes. Copper Ore is the exciting part because it leads to bars and tool upgrades, but Refined Stone is one of those quiet support materials that keeps appearing in early blueprints. If the Furnace recipe is visible but still blocked, check whether the problem is actually Refined Stone rather than Copper.
What To Do If You Do Not Have The Furnace Blueprint
If you do not have the Furnace blueprint during A Croak and a Crest, check your mailbox after sleeping and give the early-game timing a little room before assuming your save is broken. Player reports suggest that the blueprint can arrive by mail around the early first stretch of the game, and one reported case had the player stuck on Day 8 while another received it around Day 10. That makes this look more like a timing or delivery issue than a material issue.
The best move is to keep progressing other available tasks, sleep normally, and check the mail the next night. Moonlight Peaks is full of early steps that wait on letters, scenes, or the next evening, so the quest log can occasionally make you feel like you should already have a tool or blueprint before the game has actually handed it over. If you already have the Copper Ore and Refined Stone ready, do not waste the next night mining more of the same material unless you want extra Copper for future bars.
| Problem | Likely Cause | What To Do |
|---|---|---|
| A Croak and a Crest asks for Copper Bars | You need a Furnace before ore can become bars. | Check whether the Furnace blueprint is in your crafting list. |
| You have Copper Ore and Refined Stone but no blueprint | The blueprint may not have arrived yet. | Sleep, check the mailbox, and continue other tasks for a night or two. |
| The Furnace recipe appears but cannot be built | You may be short on 15 Copper Ore or 5 Refined Stone. | Mine Copper in Cave of Echoes and process enough Stone into Refined Stone. |
| You built the Furnace but cannot make Copper Bars | You may be missing Charcoal. | Use the Furnace to make Charcoal from Wood, then smelt bars with Copper Ore. |
How To Make Copper Bars After Building The Furnace
After building the Furnace, make Charcoal first if you do not already have any, then use 4 Copper Ore and 1 Charcoal to make each Copper Bar. This is the step A Croak and a Crest is usually trying to push you toward, and it is also the foundation for your first serious tool upgrades at Howling Hammer.
Because Copper Bars are used in several early systems, I would avoid treating them as disposable once the Furnace is built. Your first bars can disappear quickly into quests and upgrades, especially once you start looking at the Copper Pickaxe, Copper Axe, and other early tool improvements. If you are deciding where those bars should go after the quest step is handled, the Moonlight Peaks tool upgrade guide lays out the best upgrade order and why the Pickaxe is usually the first tool worth improving.
Best Way To Handle The Furnace Early
The best early Furnace routine is to keep Copper Ore in groups of four, keep some Wood moving into Charcoal, and avoid spending all your bars before you know the next quest or upgrade requirement. A single Copper Bar may only take 4 Copper Ore and 1 Charcoal, but the real cost is the mining trip, the fuel, and the time spent waiting on processing.
Once the Furnace is placed, I would use it in batches rather than one random bar at a time. If you know you need three Copper Bars for an upgrade, gather at least 12 Copper Ore and 3 Charcoal before starting the run. If a quest only needs one Copper Bar, make the one you need, then consider queuing extra bars if your ore supply is strong enough. The Furnace becomes much less irritating when you treat it as part of a nightly plan instead of remembering it exists only after a quest blocks you.
Is The Furnace Blueprint Bugged?
The Furnace blueprint situation may feel bugged if the quest is already asking for Copper Bars, but the safer assumption is that the game is waiting on a mail delivery, day transition, or early quest trigger. If you are still around Day 8 and have not received the blueprint, current player reports suggest waiting until around Day 10 may solve the issue, especially if you keep checking your mailbox after sleeping.
If several more nights pass and the blueprint still does not appear, then it becomes more reasonable to treat the save as potentially stuck or to look for a missed trigger. Before getting there, make sure you have slept properly, checked the mailbox, continued available main quests, and looked through the crafting menu carefully. Since Moonlight Peaks saves through sleeping, the Moonlight Peaks save guide is useful if you are testing night-to-night progression and do not want to lose the materials you already gathered.
The main thing is not to keep farming Copper Ore forever if the real blocker is the blueprint. Once you have 15 Copper Ore, 5 Refined Stone, and enough extra Copper for bars, your next progress check should be the mailbox and the crafting menu, not another panic trip through the Cave of Echoes.
