Making purple gold
NileRed
NileRed tries to make a ring from pure purple gold, a gold-aluminium intermetallic that is brittle and hard to work with. The 53-minute video follows the chemistry and many failed attempts before he produces a finished ring.
HN mentions it as a fascinating example of chemistry persistence and as something people learned from, such as discovering purple gold exists.
