PLATINUM: The Metal of Miracles
It's the late
1500's and the Spanish conquistadors are busily ransacking the
cultures of Latin America, looking for gold and silver to take back to
the mother country. Both metals are soft and can be heated into
liquids that pour into convenient bar forms, which were easier to
stack in the holds of their galleons than the exquisite objects that
were so eagerly melted down. But from time to time the explorers
come upon another silver colored metal. It didn't melt the way
silver did! "It must be some kind of inferior silver."
- so they named it platina, meaning "little silver" or
"lesser silver." Then they kicked it aside and
continued their plundering for silver and gold. They did,
however, find one practical use for the uncooperative metal: as
gunshot, in place of lead.
Over the years, the
name stuck, but not the idiom. Today, PLATINUM is a precious
metal, and in Europe, it is known as the noblest of metals, which is a
fair description of its exalted position in the metallurgical
world. Platinum's incredible strength, its density and its
absolute inertness make it the perfect metal for a variety of widely
diverse uses, such as fighting cancer, cleaning pollutants from
automobile exhaust in catalytic converters and creating incredibly
sensuous photographic prints. But when most people ponder
platinum, they think of the function it serves on the ring finger of
the left hand. PLATINUM holds a diamond more securely than any
other metal, yet it has a delicacy that is unrivaled.
Platinum also adds a
purity to jewelry that is unequaled, because it is used in a virtually
unadulterated state. Even when alloyed, it is usually combined
with a member of the platinum group, making the metal far more
precious than average gold alloy. And because the platinum group
metals are inert, they cannot cause allergic reactions. Platinum
also does not leave a black mark on the skin or clothing the way that
silver does.
In an age where
image is everything, it is fitting that platinum is still the supreme
material in the process of photographic prints. Although widely
superseded by much less expensive silver, platinum is preferred for exhibition
prints because of its great beauty. For archival use, nothing
comes close to platinum; 100-year-old prints retain their vitality and
are expected to do so for up to 500 years. Palladium is combined
with platinum to give the prints a warmer tone. Another
testimonial, another role for the noble metal. It's gone through
many incarnations in the past 400 years, but one thing's for
sure: no one is likely to use it in place of lead again, and it
is definitely not little silver.
