Bronze

Bronze is a metal alloy, primarily of copper, that holds significant practical and symbolic value within the wizarding world. It is most notably used as the material for the lowest denomination of wizarding currency, for various pieces of scholastic equipment at Hogwarts, and as the secondary house color for Ravenclaw House. Its presence is found in locations ranging from Gringotts Wizarding Bank to Hogwarts itself.

Bronze appears throughout the series in several distinct contexts, highlighting its utility and symbolic importance.

• Currency
  • The Knut is a small bronze coin that serves as the lowest denomination in the wizarding monetary system. There are 29 bronze Knuts to a silver Sickle, and 493 Knuts to a gold Galleon.
• Architecture and Statuary
  • Gringotts Wizarding Bank: The entrance to the wizarding bank in Diagon Alley features a set of burnished bronze doors, which are attended by a goblin.
  • Ravenclaw Tower: Access to the Ravenclaw common room is guarded by a bronze, eagle-shaped knocker on the door. Instead of requiring a password, this enchanted knocker poses a riddle to any who wish to enter.
  • Ministry of Magic: In the Atrium of the Ministry of Magic, the Fountain of Magical Brethren featured a golden wizard, a witch, a centaur, a goblin, and a house-elf. The witch was depicted sitting on a bronze chair.
• Scholastic Equipment
  • Bronze is a specified material for equipment required by first-year students at Hogwarts. The official school list includes:
    • A set of bronze scales for use in Potions.
    • A bronze telescope for use in Astronomy class.
• Symbolism
  • Bronze is one of the two official house colors of Ravenclaw House, paired with blue. This color combination represents the element of air. The house's association with bronze is seen in its banners and decorations, such as the blue and bronze silks attached to the lost Diadem of Ravenclaw.

• In the Warner Bros. film adaptations of the *Harry Potter* series, the house colors for Ravenclaw were changed from the book's blue and bronze to blue and silver. This change is reflected in all film-related merchandise and visual representations of the house crest and attire (film).
