What is the origin of the name "aluminum foil"?

The name 'aluminum foil' originates from the metal's properties and historical context. 'Aluminum' is derived from the Latin word 'alumen,' meaning alum, and 'foil' refers to the thin, pliable sheets it's made into. Aluminum was once rare and valuable, making it a precious metal. The term 'foil' was used to denote its thin, shiny nature, similar to gold or silver leaf. Over time, as aluminum became more abundant and affordable, the term 'aluminum foil' stuck, despite its common usage today.
