Conjures blue fire
- "She whipped out her wand, waved it, muttered something, and sent a jet of the same bluebell flames she had used on Snape at the plant. In a matter of seconds, the two boys felt it loosening its grip as it cringed away from the light and warmth."
- —Hermione using the spell against the Devil's Snare[src]
Bluebell Flames, also known as Cold Fire or Blue Flames, (incantation unknown) is a magical fire that is produced by a charm of unknown Incantation, flowing from the caster's wand in a stream or jet, which then condenses into a body of fire on a nearby object, similar to Incendio.
The flames produced are described as being bright blue, waterproof, and radiating heat only to objects held directly above it. The fire can also be touched, penetrated and held without it burning the holder, though it is known to burn materials such as clothing and plants. As such, it may be safely carried in small objects, e.g. a jar, without the object being damaged. These unique flames can also be directed to a desired location by its caster, and return to its original position.
|Hermione Granger||1991-1992||Hermione cast a bluebell flame that could be carried around in a jar.|
|She used it to set Snape's robes on fire during the first Quidditch match of her first year.|
|4 June, 1992||Hermione used this spell against Devil's Snare when she, Harry, and Ron worked through the challenges surrounding the Philosopher's Stone.|
Behind the scenes
- In the film, this spell was replaced by Lacarnum Inflamarae when Hermione attempted to distract Snape, and Lumos Solem to attack the sunlight-sensitive Devil's snare.
- In the seventh film, Ron tells Harry that he always liked these flames. In that film, the flames are depicted as normal, reddish-orange fire, though in the book they appear blue, as in the other books.
- The video game adaptions of Harry Potter depict this fire as similar to the Incendio. However, these appearances must not be considered valid, as Incendio produces normal fire, not the blue magical fire that this spell creates.
- Hand-held flames may be a variation of this spell, as both produce flames that can be safely carried.
