Picture of the Week
9 September 2013
This photo from UCL Geology Collections shows an ancient Greek hangover cure.
Amethyst, a popular gemstone, means 'not drunken' in Greek, and it was widely believed in the ancient world to halt the effects of alcohol.
Of course modern science sees no such property in amethyst. Chemically, it is virtually indistinguishable from quartz (silicon dioxide), with trace impurities and radiation effects responsible for the crystals' colour. And since glass is nothing but non-crystalline quartz, an amethyst glass won't stop a hangover any more than a wine bottle will.
UCL has a large collection of geology specimens, the oldest of which date back to 1855. Used mainly for teaching by the Earth Sciences department, they are also displayed to the public in the Rock Room between 1pm and 3pm every Friday.
