When Aluminum Was More Precious Than Gold

Today, aluminum is everywhere—from soda cans to airplane parts. But in the mid-1800s, this common metal was so rare and expensive that it cost more than gold. At its peak, aluminum fetched between $1,200-2,000 per kilogram, over twice the price of gold at the time.

The irony? Aluminum is the most abundant metal in Earth's crust, almost twice as common as iron. But there's a catch: it doesn't exist in pure form in nature. It's locked inside ores like bauxite, and unlike other metals, you can't just heat aluminum ore to extract it. The chemistry simply doesn't work that way.

Napoleon's Aluminum Cutlery

French Emperor Napoleon III was so obsessed with aluminum that he commissioned a set of aluminum cutlery for state dinners. His most honored guests ate with aluminum forks and spoons, while everyone else at the table had to make do with gold utensils. Yes, gold was the consolation prize.

The French government even displayed aluminum bars alongside the crown jewels, treating the metal like a national treasure. This wasn't just royal eccentricity—aluminum genuinely was that valuable.

America's Aluminum Flex

When the United States wanted to show off its industrial prowess in 1884, it topped the Washington Monument with a 100-ounce pyramid of aluminum. At the time, aluminum cost $1.10 per ounce—twice the price of silver. The cap was the largest piece of cast aluminum ever made, and before installation, it sat in Tiffany's window in New York City for two days, displayed like a precious jewel.

The casting company charged $225 for the cap (about $7,000 today), and tourists gawked at it as if it were made of platinum. It was essentially putting a giant pile of money on top of America's most iconic monument.

The Price Crash That Changed Everything

Then in 1886, two men—Charles Martin Hall in the United States and Paul Héroult in France—independently discovered an efficient way to extract aluminum using electrolysis. Almost overnight, the aluminum industry was revolutionized.

The price collapsed. Within 50 years, aluminum that once cost $550 per pound dropped to just 25 cents for the same amount, without even adjusting for inflation. The metal went from imperial dinnerware to disposable beer cans in just a few decades.

Today, we crumple up aluminum foil and toss it in the trash without a second thought. Napoleon III would be horrified.
