Gold
Bullion: (Symbol
Au) A soft, yellow, corrosion-resistant element, the
most malleable and ductile metal, occurring in veins and alluvial deposits
and recovered by mining or by panning or sluicing. A good thermal and
electrical conductor, gold is generally alloyed to increase its strength,
and it is used as an international monetary standard, in jewelry, for
decoration, and as a plated coating on a wide variety of electrical and
mechanical components. Atomic number 79; atomic weight 196.967; melting
point 1,063.0°C; boiling point 2,966.0°C; specific gravity 19.32; valence
1, 3.

Gold Ever Since it's Discovery it has
drawn the attention of Men who search it out!
Ever since its discovery
5,000 years ago, gold has been treasured for its unmatched luster,
beauty and intrinsic value. Today, gold continues to enjoy
widespread appeal as an investment and storehouse of value. Gold is
an internationally recognized monetary and financial asset held in
reserve by major governments. It is so rare that all the gold ever
mined could fit into a cube measuring just 20 yards on each side.
What is Gold?
Gold is a heavy, yellow, metallic chemical element. It is a precious
metal, with a high degree of ductility and malleability, that is
used in the manufacture of a wide range of products including
jewelry, electronics, and coinage. Gold forms in high temperature
hydrothermal quartz veins. These veins carry the gold to the earth's
surface through super heated solutions and this material deposits in
fissures to form ore bodies. Erosion of the host rock by wind and
water washes the gold from the ore bodies. Some of the gold stays
near the vein and water carries some of the gold into rivers and
streams. The gold nuggets found in rivers and streams are known as
placer gold while the gold found in ore bodies and veins is known as
lode gold. Typically, the old timers would follow placer deposits to
the source, or lode gold, and then start hard rock mining.
Investing in Gold is a
stable investment with a more than 4,000 year history of use by
humans. Gold is the most stable of all investments and is an
excellent hedge against inflation and deflation. Buy Gold and
Buy Silver just buy the metals to protect your current and future
wealth! There is a company called: GoldMoney.com that
provides a way for you to buy gold safely and securely and trade it
right over the Internet while having actual possession of the gold
in an insured vault, thus creating truly insured
gold bullion.
Mineral symbol: Au, hardness: 2.5-3, specific gravity: 19.29, color:

How is Gold Weighed?
The weight of gold or gold articles is usually expressed in troy
ounces.
1 troy ounce = 1.097 ordinary ounce
12 troy ounce=1 troy pound
31.1 grams=1 troy ounce
1.55 grams=1 pennyweight (1dwt)
20 pennyweight (dwt) = 1 troy ounce
24 grains=1 pennyweight (dwt)
480 grains=1 troy ounce
How is Purity Measured?
The purity of gold articles is generally described in three ways:
Percent Fineness Karats
(parts of gold per 100) (parts of gold per 1000) (parts of gold per
24)
100 percent 999 fine 24 karat
91.7 percent 917 fine 22 karat
75.0 percent 750 fine 18 karat
58.3 percent 583 fine 14 karat
41.6 percent 416 fine 10 karat
What Does it Mean?
Gold Filled: Also called gold overlay, a layer of at least
10-karat gold permanently bonded by heat and pressure to one or more
surfaces of a support metal, then rolled or drawn to a prescribed
thickness. The karat gold must be at least 1/10 by weight of the
total metal content.
Rolled Gold Plate: Material consisting of a layer of plating
of 10-karat gold or better which is mechanically bonded to a base
metal. The karat gold content may be less than 1/20 but must be
properly identified by weight in terms of total metal content.
Vermeil: Gold at least 15- micro-inches thick, bonded to
sterling silver by an electrolytic or mechanical process.
Gold Leaf: Pure gold that is pounded into sheets applied to
other surfaces by hand. Usually about 3 micro-inches thick.
