Metals made possible advances in
• agriculture,
• transportation,
• communication,
• technology, and
• warfare
The industrial revolution has been
entirely dependent on metallurgy

Metals - Greek: “metallon” = mine, quarry
Definition: Materials hard, dense, opaque,
shiny, with good electrical and thermal
conductivity
Fusible, malleable, ductile
Gold leaf transmits green light
Lithium = least dense; Osmium = densest

Major source of metal ore, as well as lumber
The priesthood became a major power in the Assyrian society
Long wars fought that helped build Assyria into a warrior society
Social position of women was lower than in the neighboring societies.
Assyria was open to homosexual relationships between men
Assyrian domination spanned from the Caucasus Mountains in the north
to Egypt, Libya, and Arabia in the south, and from Cyprus in the
west to Persia and the Caspian Sea in the east
Decline due to civil wars and political instability
Assyria conquered by Alexander Macedon in 322 BC

Lebanon, and the copper of Magan
Consolidation of the city-states of Sumer and Akkad
Growing economic and political power
The empire's breadbasket was the rain-fed agricultural system
of Assyria and a chain of fortresses built to control the
imperial wheat production

6000 BC - the early inhabitants of Mesoamerica were
domesticating plants
Barley and wheat cultivated
All regions of Mesoamerica cultivated the base crops of
maize, beans, and squashes
All Mesoamerican cultures used stone age technology
c.1000 AD copper, silver, and gold were worked
Mesoamerica lacked draft animals. Did not use the wheel,
and possessed few domesticated animals
The principal means of transport were on foot or by canoe

Precious metals measured in troy ounces
One troy ounce = 1.09714 regular (avoirdupois) ounces =
31.1034768 g
Karat indicates the gold purity 24 k = pure gold (0.995)
For many years money had to be backed by gold
1930 - Gold Standard Act established gold as international
trade standard (USA Dollar = 25 8/10 grains of 90% gold)
1944 – Bretton Woods Conference: USA major influence
US dollar = International Standard. No more gold standard
Price fluctuated. Since 1975 gold price depends on free market
Inflation and bear or instable markets increase its price.

Toxicity: Gold salts are toxic to liver, kidneys, skin (Chrysiasis)
Drinks: Danziger Goldwasser - flakes of gold are inert
Medicine: Much used in the past for treatment of
tuberculosis– ineffective
Some gold salts have been used in the treatment
of rheumatoid arthritis

4000 BC - Separated from lead. One of the 7 metals of
antiquity.
1500 BC – Egypt – Silver more expensive than gold
700 BC – Kingdom of Lydia (Asia Minor) coins of silver
alloy with gold (“electrum”)
Silver sources: Phoenicians - Spain, Greeks - Laurium, Romans - Sardinia
Silver in the money of many nations in Europe, China, India, Japan
Pound sterling of UK (£) = Sterling silver
In many languages the word “silver” = money
19th cent. - Much silver mined in Americas
1947 - Most coins made of cupro-nickel
1970 - Last circulating silver coin (US half-dollar)

Industrial Revolution – Increased demand for
plumbing, painting, and gasoline additive
Lead paint – Children lead intoxication
Lead more dangerous if fumes are inhaled
19th Cent. – Lead causes mental disorders
Lead causes blindness
1921 – Tetraethyl lead added to gasoline to avoid
“knocking”. Phased out
1930-2000 – Enormous US and European legislation
on high lead blood levels to 2% of population
Lead Economics, Health, and Politics

Italian: bronza (bell) French: bronze
Bronze is an alloy of copper + 12% tin
Various alloys hardening the copper
Sumer, India, China and Japan - 4000 BC
Followed by the Iron Age (~1300 BC)
• Harder than iron; does not rust
• Iron easier to find and process but requires
higher temps.
• Disruption in tin supply (?)
