Bell foundries are specialized facilities where bells are cast and manufactured. These foundries use a combination of metal alloys, typically bronze, to create bells of various sizes and tones. The process involves melting the metal, pouring it into molds, and allowing it to cool and solidify. In addition to producing bells for churches and public buildings, bell foundries often create smaller bells for schools and decorative purposes. Famous bell foundries, such as Whitechapel Bell Foundry in London, have a long history of crafting iconic bells, including the Big Ben bell in the Elizabeth Tower.
