Celestial bronze is mined by the Cyclopes from Mount Olympus. The ore is shaped by tempering the metal in Mount Etna and cooling it in the River Lethe. The metal is deadly to creatures of the magical world. Unlike mortals, demigods are also affected by it because of their blood. Artifacts of celestial bronze are known to emit a faint bronze glow. The metal is able to disperse monsters into dust once a weapon made of Celestial bronze passes through them.
Known Celestial Bronze Weapons
- Annabeth's Knife
- Backbiter (partly steel)
- Thalia's Spear
- Zeus' Master Bolt
- Poseidon's Trident
- Orion's mechanical eyes
- Orion's bow (the handle)
- According to Reyna, Celestial Bronze is much rarer than Imperial Gold. Although this might have been due to the Roman's camp location.
- Celestial Bronze is one of three magical ores, the others being Imperial Gold and Stygian Iron. However, in Percy Jackson's Greek Gods, Adamantium is also mentioned.
- It gives a faint light as in the case of Riptide.
- With the exception of Stygian Iron, Celestial Bronze and Imperial Gold are the only metals which turn monsters into dust.
- "Celestial" means "from the sky" or "heavenly."
- While Celestial Bronze is normally mined from Olympus, if Hephaestus is upset with his work, he throws pieces of Celestial Bronze into the mortal world.
- As it is not silver, it cannot harm lycanthropes.
- Unlike Imperial Gold, Celestial Bronze seems almost as abundant as iron to Greek Demigods, as not only their weapons made out of it, but it seems like almost everything the Greek Demigods make is made out of it, using it as a magical alternative to what other metals would normally be used for weapons. Though this is justified as its mined from Olympus which is right above the Empire State Building.
- Annabeth's father, Dr. Frederick Chase, melted down her weapons and turned them into bullets, which he fired at monsters out of his Sopwith Camel in The Titan's Curse.
- Celestial Bronze can hurt the Egyptian magicians as seen in The Son of Sobek.
- In The Demigod Diaries, Luke Castellan says that he once had a sword made of Celestial Bronze but it was destroyed by the acid of a monster.
- Celestial Bronze is the sacred metal of the Greeks, which explains why Camp Half-Blood mostly uses Celestial Bronze weapons, while Camp Jupiter uses mostly Imperial Gold.
- Just like Imperial Gold, a stab wound from Celestial Bronze can damage not only the body, but the soul of a demigod as well. It is unknown but probable that Stygian Iron can do the same.
