This spell was used nonverbally by Professor Remus Lupin in 1993 in order to heat up his kettle so that he could make tea for himself and Harry Potter. When he cast it, a blast of steam issued almost instantly from the kettle, after which he prepared the drink.

Behind the scenesEdit

• It is unknown if this could be used to heat things up in general or if it is exclusive to kettles.
• This may be a variation of Incendio.
