Historie
Mercury was known to the ancient Chinese and Indians and has been found in Egyptian tombs dating back to about 1500 BC.
Alchemists thought of mercury as the First Matter from which all metals were formed.
They believed that different metals could be produced by varying the quality and quantity of sulfur contained within the mercury.

Anvendelser
Mercury is used in barometers and manometers because of its high density.
Gaseous mercury is used in mercury-vapor lamps and some 'neon sign' type advertising signs and fluorescent lamps.
Mercury is also found in liquid mirror telescopes.
Gaseous mercury is also found in some electron tubes, including ignitrons, thyratrons, and mercury arc rectifiers.
