Bluebell Flames

The Bluebell Flames charm produces fire. These special flames are bright blue in colour and do not cause the damage of normal fire, surfaces it comes in contact with are not affected. These flames can be scooped up in the hand and carried around or put in a jar. This suggests that the flames do not need fuel or oxygen, but they still expell heat and light.In 1997, Harry Potter mentions that Hermione Granger was particularly adept in conjuring bluebell flames, alluding to her successful use of them in 1991

According to Harry Potter and the Goblet of Fire (video game) (GBA version), they are produced by the Incendio Charm, though in the books, the incantation is unknown but often mistaken to be the Incendio Charm though this incantation is proven to conjure actual fire in 1994 when Arthur Weasley used it in the Dursleys fireplace in order to travel via the Floo Network to The Burrow.

Uses
In 1991 Hermione produced Bluebell Flames to keep warm in the courtyard and later used them to distract Severus Snape in order to break his eye-contact with Harry whilst trying to mutter the counter-jinx to combat Quirinus Quirrell who was trying to throw Harry off his broom in his first Quidditch match. In 1997 and 1998 whilst 'on-the-run' during the Second Wizarding War, Hermione conjured these flames in order to keep warm and to cook with.

Behind the scenes
In Harry Potter and the Philosopher's Stone (film) their use was replaced by another Charm (Lacarnum Inflammare)
