Silver, “Periodic Table of Poetry” poem by Chicago poet Janet Kuypers

Silver

Janet Kuypers

from the “ Periodic Table of Poetry” series (#47, Ag)

Got a huge batch of silver bars,
but didn’t want to sell them
because at the time the value of Silver
temporarily dropped.
But the thing is, with all that Silver,
I would have had to pay
people to store it,
costing me even more money.
So I buried it,
and waited for the value of Silver
to rise again
before I cashed my Silver in.

#

I never got the Silverware
from my grandparents,
I was too young
and they lived too long,
but I got the silverware case
from my brothers house
when he moved out
of his last hone.

#

My engagement ring
was originally the wedding ring
of my husband’s great-grandmother.
But that engagement ring
(with a diamond in a white gold setting)
later became a pendant,
and after the fragile
white gold chain broke
(because even though it’s heavy,
it’s expensive, so it was thin),
we replaced it with a Silver chain,
thicker, and therefore stronger,
and worked perfectly
to showcase that diamond
around my neck for years.

#

Silver, mixed with other metals,
can make amalgams, for people
like me with too many
cavities to count. Silver may be
a worthwhile metal element,
but I was relieved
when the dentist
fixed those fillings
with an amalgam matching
the color of my teeth…

#

I worked for years for a minor
in photography in college,
aced every course
from photojournalism to
portrait to art photography.
I’d wind my own film,
coated with an emulsion
containing light-sensitive
Silver halide salts. I loved
working in that darkroom,
seeing images appear
that I captured with my
Silver-emulsion film.

#

I’ve collected Silver coins for years,
and traveling around the globe
has increased my desire
for coins from other countries.
And my mother, years ago
played the dollar slots in Vegas
(back in the day when the slot machines
paid cash directly to you,
and didn’t give you a card
you needed to cash in),
and she won tons of old Silver dollars.
For decades she kept a jar
in the cabinet in the kitchen
(labeled “Maw”)
filled with these Silver dollars.
The Silver dollars were given to me
after she passed away,
and now I have stacks of these
century-old Silver dollars
displayed with all of
my other Silver and metal coins
from around the world.
I know the 1888 Silver dollar
in that collection is so worn
that it can’t be worth much,
but trust me, for sentimental value,
it’s priceless.

Lutetium poem by Janet Kuypers

Lutetium

Janet Kuypers

from the “ Periodic Table of Poetry” series (#71, Lu)

When I was little
and first fell in love
with the stars in the sky,
it was always easy
to spot the constellation
Cassiopeia at night —
just look for five dots
that looked like the letter “w”
as the throne for Cassiopeia,
queen of Aethiopia.
But apparently the Germans
had a thing for Cassiopeia too,
because an Austrian,
a Frenchman and an American
all independently discovered
the element Lutetium
at the same time…
After years of debate,
the Frenchman won
the naming rights for Lutetium,
but the Germans still
stuck with Cassiopeia
for their name-of-choice
through the nineteen fifties.

But I don’t know, maybe
this element Lutetium
was the perfect thing
for queen Cassiopeia,
because although it is
more common than silver
here on Earth,
it’s hard to separate
from other elements,
and it’s harder and denser
than it’s counterparts
(even costing ten thousand
dollars per kilogram).

#

If I could have photographed
queen Cassiopeia,
I may have wanted
Lutetium aluminum garnet
as the liquid element
in immersion lithography
for added depth-of-focus
in my photo journalism travails…
Though maybe I should just
savor the connection
between queen Cassiopeia
(with her throne in the sky),
the mother of Andromeda
(goddess and galaxy),
and Lutetium —
something that has always
been so strong,
and has also worked
with others, to help us see
everything so much better…

lutetium electron structure
    * Germans used cassiopium (Cp), after the constellation Cassiopeia, as the name for element 71 (Lutetium) until the 1950s.
Lutetium is not a particularly abundant element, though significantly more common than silver in the earth’s crust; it has few specific uses, but is found with almost all other rare-earth metals but never by itself.
Lutetium is very difficult to separate from other elements, and pure Lutetium metal is very difficult to prepare. Even though it is more common than silver, it is one of the rarest and most expensive of the rare earth metals with the price about US$10,000 per kilogram, or about one-fourth that of gold. Lutetium also has the highest density, melting point, and hardness of the lanthanides.
For an application for Lutetium: Immersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. Currently, the most promising high-index lens material is Lutetium aluminum garnet.
