Brass in Africa
Some of the most famous objects in African art are the lost wax
castings of West Africa, mostly from what is now Nigeria, produced
first by the Kingdom of Ife and then the Benin Empire. Though
normally described as "bronzes", the Benin Bronze plaques, now
mostly in the British Museum and other Western collections, and the
large portrait heads such as the Ife Head of "heavily leaded
zinc-brass" and the Bronze Head of Queen Idia, both also British
Museum, are better described as brass, though of variable
compositions. Work in brass or bronze continued to be important in
Benin art and other West African traditions such as Akan
goldweights, where the metal was regarded as a more valuable
material than in Europe.
Copper is a chemical element with symbol Cu (from Latin: cuprum)
and atomic number 29. It is a soft, malleable, and ductile metal
with very high thermal and electrical conductivity. A freshly
exposed surface of pure copper has a reddish-orange color. Copper
is used as a conductor of heat and electricity, as a building
material, and as a constituent of various metal alloys, such as
sterling silver used in jewelry, cupronickel used to make marine
hardware and coins, and constantan used in strain gauges and
thermocouples for temperature measurement.
Copper is one of the few metals that occur in nature in directly
usable metallic form as opposed to needing extraction from an ore.
This led to very early human use, from c. 8000 BC. It was the first
metal to be smelted from its ore, c. 5000 BC, the first metal to be
cast into a shape in a mold, c. 4000 BC and the first metal to be
purposefully alloyed with another metal, tin, to create bronze, c.
Eventually it was discovered that metallic zinc could be alloyed
with copper to make brass; a process known as speltering and by
1657 the German chemist Johann Glauber had recognised that calamine
was "nothing else but unmeltable zinc" and that zinc was a "half
ripe metal."However some earlier high zinc, low iron brasses such
as the 1530 Wightman brass memorial plaque from England may have
been made by alloying copper with zinc and include traces of
cadmium similar those found in some zinc ingots from China.
