Mercury’s symbol Hg comes from its Greek name, hydrargyrum, meaning "liquid silver", due to its mobility and shiny surface. Mercury is used in electrical switches of thermostats, but it is most commonly seen in the new the compact fluorescent light bulbs. Interestingly, mercury nitrate played a role in the term "mad as a hatter". As mercury was used in the making of hats from animal pelts in the 18th century as it was used to clean the pelts before they turned them into hats. It was then discovered that a large percentage of the hatters working with it ended up suffering from brain damage due to mercury exposure. Mercury was found in Egyptian tombs that date back to 1500 BC. Amazingly, in China and Tibet, it was thought to prolong life, heal fractures, and maintain generally good health, although it is now known that exposure to mercury vapour leads to serious adverse health effects.
