Gold is a malleable, heavy, naturally occurring element. It is about 19 times
heavier than the same volume of water. Gold is found in hard rock known as
lode,
or as pieces which have broken away from their source and traveled some distance.
Such gold is known as placer.
The most common measure of weight in the United States and Britain is
called avoirdupois. However precious metals are measured in troy weight. The
