What is aluminum?

What made aluminum valuable back then was poor smelting technology.

Aluminum was only discovered in the 19th century, yet strangely enough, it was not formally refined until long after it had been discovered and had already earned its name.

When aluminum was first refined, it was treated as a precious metal, as jewelry. The king of Thailand used an aluminum watch chain; At the International Exposition of Paris in 1855, a small piece of aluminum was displayed, labeled "Silver from clay," and placed next to the most precious jewels. In 1889, Russia's czar presented Mendeleev with an aluminum trophy for compiling the periodic table of the chemical elements.
