Copper Bar
Requires a Furnace.
Quick Answer
Copper Bar
The normal way to get Copper Bar is to process Copper Ore in a Furnace. One batch takes 1 Copper Ore and returns 2 Copper Bars. If you already have the ore but cannot make a Copper Bar, the missing piece is usually the Furnace itself or its setup, not another mining unlock.
Make Copper Bar using the Furnace.
Recipe
The recorded conversion, with the input and output the data actually states.
| Made in | Furnace |
|---|---|
| Input | Copper Ore×1 |
| Output | Copper Bar×2 |
| Fuel | None recorded |
| Time | None recorded |
| Earliest access | Requires a Furnace. |
| Recorded price | 60 — one stored value |
| Can also be bought? | Yes, from a rotating shop |
| Can also be found? | Yes, as later loot |
One batch turns 1 Copper Ore into 2 Copper Bars — enough for Copper Bars to be worth smelting in bulk rather than one at a time. Neither a fuel cost nor a processing timer is recorded for this recipe.
Can I get Copper Bars yet?
The answer depends on where you are, not on the item itself.
If you have a Furnace
Yes. Get Copper Ore and process it — the recipe runs with the ore alone.
If you have Copper Ore but no Furnace
Not through processing yet. Unlock your first Furnace — the chain is below.
If the Workshop route is not open
The Furnace is tied to the Workshop progression, so that chain comes before the recipe.
If you are already in later areas
You may also buy or find Copper Bars elsewhere — see the alternatives below.
What you need first
Each of these is stated once. Finish them in this order and the recipe will run.

How to make Copper Bar
Step 1 — Get 1 Copper Ore
Best early source: Find / loot · Farm Mine — Floor 1.
Step 2 — Use the Furnace
Place the Furnace, then load 1 Copper Ore. No fuel is recorded for this conversion, so the ore is the only thing consumed.
Step 3 — Collect the output
Each batch yields 2 Copper Bars. The game data records no processing timer, so it does not state how long a batch takes.

Copper Ore vs Copper Bar
These two are the most common mix-up in the early game, in whichever direction you are coming from.
| Copper Ore | Copper Bar |
|---|---|
| Raw material, mined or bought | Processed material, made in a Furnace |
| Accepted by quests that ask for ore | Accepted by crafting recipes that ask for bars |
| Cannot substitute for a Copper Bar in a recipe | Cannot substitute for Copper Ore in an ore hand-in |
Why can’t I make Copper Bar?
Not having the ore and not being able to process it are different problems. Pick the one that matches you.
What’s stopping you?
The earliest recorded source is Find / loot · Farm Mine — Floor 1. Mine the nodes on the earliest floor you can reach and smelt in bulk, since one batch returns 2 Copper Bars.
Other ways to get Copper Bar
Later alternative: Copper Bars can also appear as loot in later mining areas. These routes are chance-based, so the recipe above stays the reliable one.
| Alternative | Availability | Reliability | Notes |
|---|---|---|---|
| Find / lootCatacombs Mines | Alternative route | Random | 4 per find · Unlock and enter the Catacombs. |
| Find / lootCatacombs Mines 2 | Alternative route | Random | 4 per find · Use a Small Mine Key on the rusted door in the Catacombs Mines and win the battle. |
| BuyGarbage Shop | Alternative route | Rotating | Up to 5 in stock · Only lists on stock roll 7 |
| Mail rewardMailbox · Molly — A small gift | Later | Fixed | 2 in the mail |
Rotating stock is not a guarantee: the Garbage Shop listing only appears on stock roll 7, and the data does not record how often that comes up. If you need Copper Bars now, smelting your own is the reliable route.
What is Copper Bar used for?
34 recorded recipes consume Copper Bar. This is what makes it worth keeping rather than selling.
Quest-critical
The recorded recipe also takes Iron Bar, Gold Bar, Bones. It takes smelted materials, never the raw ore, so Copper Ore will not substitute here.
How many the quest needs is recorded in the quest guide rather than in the recipe data. Open the Giant Skull Chalice guide →

What else the Furnace makes
The Furnace handles more than one ore, so the same setup covers the other bars you will need.
| Input | Output |
|---|---|
| Copper Ore ×1 | Copper Bar ×2 |
| Gold Ore ×1 | Gold Bar ×5 |
| Iron Ore ×1 | Iron Bar ×3 |
| Scrap Metal ×5 | Iron Bar ×3 |
| Scraped Hide ×1 | Leather ×1 |
| Platinum Ore ×1 | Platinum Bar ×18 |
| Verdite Ore ×1 | Verdite Bar ×12 |
| Raw Void Crystal ×1 | Void Crystal Bar ×8 |
How many Copper Bars do you need?
Uses the recorded ratio, so the count is exact rather than a rule of thumb.
That is 4 batches, so bring 4 Copper Ores. Each batch returns 2 Copper Bars, so 4 batches cover the 8 you need.
Keep them or sell them?
34 recipes take Copper Bar, so it is an input for the next stage of crafting rather than something to sell off. The item database records a single price of 60 and does not store a separate sell value, so a resale figure would be a guess. Hold the bars until the recipes that need them are built.
FAQ
How much Copper Ore does one Copper Bar take?
One batch is recorded as 1 Copper Ore in and 2 Copper Bars out. There is no way to run a smaller batch, so the ratio is fixed.
Does Furnace need fuel?
No fuel cost is recorded for this recipe. The data records the input, the output and nothing else, so nothing is charged beyond the Copper Ore.
Can I buy Copper Bars instead of making them?
Only from a rotating shop listing, which is a chance rather than a guarantee. Smelting is the reliable route.
Can Copper Ore be used instead of Copper Bar?
No. Recipes that ask for Copper Bars will not accept Copper Ore, and quests that ask for Copper Ore will not accept Copper Bar. They are separate items.
Does one Copper Ore give one Copper Bar?
No — the recorded batch is 1 Copper Ore to 2 Copper Bars, so every Copper Ore you smelt returns more than one bar. Mine a small stack and process it together.
