"From lighting a warm hearth to igniting a Christmas pudding, the Fire-Making Spell is always useful around the wizarding household. However, the ability to produce fire with the flick of a wand can be dangerous to your fellow students (and worse, your books)."
Miranda Goshawk, Book of Spells[src]

The Fire-Making Spell[2], also known as the Fire-Making Charm[3] (Incendio[3][1][2]) is a charm and a form of Conjuration, that can be used to conjure a jet of orange and red flame. Thereby this spell can be used to set things alight[2].


This spell is listed in The Standard Book of Spells, Grade 1 by Miranda Goshawk. This spell is also taught to students during their first year in Herbology class to deal with Devil's Snare, in second year Defence Against the Dark Arts[4] and is reviewed in the fifth year for students sitting the O.W.L. exams.

Known uses

"Flames rose at once in the fireplace, crackling merrily as though they had been burning for hours."
—Arthur Weasley uses this spell at the Dursleys' house[src]

Known practitioners


  • In Latin, incendio is the dative or ablative singular of incendium, "fire", and can mean "to fire" or "for fire" (dative), "by fire" or "with fire" (ablative of instrument or means). Thus, the incantation is a way of calling upon fire to burn a desired object, since the spell caster wills harm to be done to an object "by (means of) fire."
  • The magic word could also be a variant of the Latin incendo, "I set [something] on fire", with an "i" added before the final "o" for euphony.
  • "Incendio" is the Spanish and Portuguese word for "wild fire". Also, in Italian, the word "Incendio" refers to a great fire similar to that one made by Thorfinn to Hagrid's house.
  • "Incendio" (pronounced in-cen-DI-u) is also the first person singular of the present of the Spanish and Portuguese verb "incendiar", meaning "to set fire to".

Behind the scenes

  • This may be the spell Remus Lupin used on the Hogwarts Express 1993, combined with a Flame-Freezing Charm when the lights went out as he is described as "holding a handful of flames" though it is more likely that he used the charm for Bluebell Flames[17]. This may also be the spell he used to relight candles during the Patronus lesson[15].
  • In the video game adaptations of Philosopher's Stone and Chamber of Secrets, Incendio is the Bluebell flames charm Hermione uses in the first book. It is used primarily to wilt dank-loving, threatening plants and burn through spider webs. In the later games, it resumes its use as a spell to conjure a small burst of normal fire.
    • Also in the second game, the manuals, and in-game info states it can be used as a duelling charm, despite that in the console versions it is the last spell to be learned in the game, thus duels are no longer as abundant. However, proof of this can be seen in that if the player times it right, they can cast their own Disarming Charm on the incoming mis-cast Indencio (as it flies back to hit the player) and thus catching the spell and mitigating it. This also works with Flipendo.
  • When Rowle used the spell offensively against Hagrid's hut, it caused an explosion, rather than simply lighting it on fire.
  • Incendio is the first known spell to be cast in the series, although magical devices (Albus's Put-Outer), abilities (Animagi) and beings (Hagrid) appeared before.
  • In the film adaptation of Harry Potter and the Half-Blood Prince, Bellatrix uses this spell to set Hagrid's hut on fire instead of Rowle.
  • In Harry Potter for Kinect Harry and Voldemort can use this spell against each other in the final battle during Voldemort's Last Stand as they engage in a normal duel.
  • This spell is mentioned in the lyrics of Celestina Warbeck's song A Cauldronn full of Hot, Strong Love.
  • It's unknown why this spell is considered a charm, as conjuration is a form of transfiguration.
