GOLD
Gold was made into art objects and jewelry as far back as 4000 BC
Alchemists, the forerunners of today's chemists, attempted to turn base metal into gold
Gold does not tarnish, rust or corrode
One cubic foot of gold weighs more than half a ton

PLATINUM
Platinum is the rarest of all precious metals
Approximately 10 tons of raw ore have to be mined to produce one pure ounce of platinum
The main producers of platinum are the former Soviet Republics, South Africa, and Canada
All the platinum ever mined would fill a cube less than 25 feet on each side
Scarce metals, such as platinum, face depletion risks this century because of the lack of suitable substances in such devices as catalytic converters and hydrogen fuel cells.
