Flagrante Curse
From UnknowableWiki
The Flagrante Curse is a spell that causes an object to become red-hot, burning all it touches (DH26).
Gringotts Wizarding Bank uses the Flagrante Curse as a security measure in its vaults; should someone grab something that is not theirs, they will be burned by the object, forcing them to drop it. The bank often uses the Flagrante Curse in conjunction with the Gemino Curse (DH26).
