Brass

"The sun shone brightly on a stack of cauldrons outside the nearest shop. 'Cauldrons — All Sizes — Copper, Brass, Pewter, Silver — Self-Stirring — Collapsible', said a sign hanging over them."

- Description of Potage's Cauldron Shop.

Brass is an alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying hardness and other properties.

The number four on the Dursleys' front door in Privet Drive was made of brass. Every new Hogwarts student had to be equipped with a set of Brass scales, which they could purchase at Wiseacre's Wizarding Equipment. The goblins of Gringotts Wizarding Bank weighed coins in brass scales. One could also buy collapsible brass telescopes at Wiseacre's. Brass Cauldrons were sold at Potage's Cauldron Shop, in Diagon Alley, for a price of twenty-five Galleons. The junk shop sold "lopsided brass scales" as well. The doorknob of Moaning Myrtle's bathroom was made of brass, as was the griffin-shaped knocker on the door to the Headmaster's office, and the plaque saying "Sybill Trelawney, Divination teacher" outside the circular trapdoor leading to the Divination Classroom at Hogwarts Castle. On the Hogwarts kitchens, mounds of glittering brass pots and pans are kept heaped around the stone walls. Rubeus Hagrid owned brass pots, which he kept hanging from the ceiling of his Rubeus Hagrid's cabin. The Broomstick Servicing Kit that Hermione Granger offered Harry Potter for his thirteenth birthday included a tiny brass compass to clip on one's broom during long journeys. The bedsteads of the Knight Bus were made of brass, as was the number eleven outside Room 11 in the Leaky Cauldron. Omnioculars were also made of brass. The instrument to check the wood, core and length of wands of wizards arriving at the Ministry of Magic was made of brass. Brass was also the metal out of which plaques outside office doors at the Ministry were made of, such as the Misuse of Muggle Artifacts Office. In the 1995–1996 school year, when the Dumbledore's Army started using the Room of Requirement as a safe place in which to practice defensive magic, the door to the room materialised as a highly polished door with a brass handle. At St. Mungo's Hospital for Magical Maladies and Injuries, at the entrance to the "Dangerous" Dai Llewellyn Ward, there was a brass holder with a card identifying the Healer-in-Charge (Hippocrates Smethwyck and the Trainee Healer (Augustus Pye). During her lifetime, Hepzibah Smith kept many flourishing potted plants in brass containers all over her sitting room, which was noted to look like a cross between a magical antique shop and a conservatory. The passageway behind Ariana Dumbledore's portrait that linked the Hog's Head Inn to the Room of Requirement during the 1997–1998 school year, was lit by brass lamps hanging from the wall.
