Celestium Bars are a refined metal in Enshrouded, smelted from raw ore that formed where a meteorite struck Cinder’s Cradle. You cannot pick a bar up directly in the world in any reliable way. Instead you gather two raw materials and process them together at a Blast Furnace.
Quick answer: Smelt 20 Celestium Ore and 40 Coal in a Blast Furnace to produce 20 Celestium Bars per batch.
Celestium Bars recipe and requirements
Celestium Bars are crafted only at the Blast Furnace, an upgraded smelting station. One smelting cycle takes 12 minutes and yields 20 bars. The ratio is fixed, so queue in multiples if you need a larger stockpile.
| Input | Amount | Output | Time |
|---|---|---|---|
 Celestium Ore | 20 | 20 Celestium Bars | 12 min |
 Coal | 40 | — | — |
The Blast Furnace itself must be built under a roof and unlocks after you pick up Bellows. It holds nine recipes in total, so Celestium Bars share the station with materials like Gold Bars, Glass, and Bronze Bars.
Where to mine Celestium Ore in Cinder’s Cradle
Celestium Ore is a level 45 material found only in Cinder’s Cradle, the volcanic region sitting above the Ancient Gate and Starfish Shores. Travel there and head for the mine sites clustered around the Ancient Gate, near Cromville Hot Spring.
The ore sits inside cave deposits as glowing veins. Point your reticle at a vein and mine it with a pickaxe until the loot drops. A Gilded Pickaxe works well for the harder deposits found this deep.
Where to gather Coal in the Albaneve Summits
Coal is a level 33 material from the Albaneve Summits, the snowy biome. Look north of the Ancient Spire there, along the icy river, where lumps of Coal can be collected. You need double the Coal that you have ore, so gather at least 40 for a single batch of bars.
Smelt Celestium Bars at the Blast Furnace
Once the timer expires, 20 Celestium Bars in the furnace output confirm the process worked. Their description calls them refined metal with a finish that transitions from pale blue to deep violet. You can stack up to 250 bars.
Celestium Bars also have a small chance to appear inside Golden, Silver, Wooden, and Locked Chests as well as Sarcophagi, so grab any you find while exploring to save on smelting time.
Material reference for the Celestium Bars chain
Each item in the smelting chain sits at a different level and comes from a different region. These are the figures to check your inventory against before you start a batch.
| Material | Item level | Rarity | Source |
|---|---|---|---|
| Celestium Ore | 45 | Common | Cinder’s Cradle |
| Coal | 33 | Common | Albaneve Summits |
 Celestium Bars | 45 | Common | Blast Furnace |
What Celestium Bars are used for
Celestium Bars feed a wide range of high-level crafting. They go into Flame Altar upgrades and into late-game weapons such as the Greater Golden Twinflame Sword, Guard Of The North Sword, Golden War Hero Axe, Jezmina’s Apotheosis, the Electric Initialiser, Proto Matter-Bender, Valor Heart Daggers, Shroud Vessel’s Greatsword, and the Sacrificial Vukah Dagger.
The bars also unlock and craft tools like the Celestium Pickaxe and Celestium Axe, Celestium and Eternal arrows, several Ancient and Golden building pieces, and decorative items such as the Celestium Platter. Keeping a steady supply on hand means you rarely have to pause a build or an upgrade to run back to Cinder’s Cradle for more ore.
