My father’s taxidermist and slaughterhouse business was an overwhelming environment for me as a child. Scenes of hanging carcasses of deer, piles of sawed-off animal feet and freezers full of animal hides left me with powerful images, ones that presented a lack of empathy for life.
The goal of my artwork is to create a sensory experience or narrative that refers to memories of this provocative atmosphere, and also to evoke the animal spirit that was once destroyed and to make amends for the discord and waste. While my father’s vocation was to permanent displays frozen in time, my work conjures the past, present and future to invoke a contemplation of our existence. I attempt to expose the unseen core, the essential structure of skeletal or embryonic animal references. I find that these references offer me an opportunity to understand our own growth and decay.
|Catch of the Day
There are many ways to prepare fish—fried,
grilled, smoked, sauteed-however, you can make a clay fish using a
plaster mold and “barbecue” it in a raku firing. Ironically, my mold
(figure 1) is the same taxidermist mold that my father used for
thirty-five years to mount fish. I remember the day I helped him make
that plaster mold after he caught a twelve pound bass and decided to
make it one of his “frozen memories”.
|To follow the process for creating a skeletal fish similar to the ones
I use in my work, begin with twenty pounds of white raku clay (or
whatever amount is appropriate for the scale of your press mold). Compress the clay into the completely dry plaster mold (figures 2 and
3). Smooth out the surface of the clay and allow it to stiffen for at
least two hours.
As soon as the clay sets up, gently begin to separate it from the
plaster mold (figure 4).
|Next, cut away the excess clay using a
fettling knife (figure 5).
|Shape the bottom of the fish by carving away more clay (figure 6).|
|Begin to bend and alter the fish into a more active gesture (figure 7)
and prop it up using wads of clay so that it maintains this shape.
|Now you’re ready to begin carving away the clay to create the skeletal
framework of the fish. Use small and large loop tools to carve the
space between the spine and the ribs, and define where the skull begins
(figure 8). In addition to carving, add more clay to enhance the form,
creating a more anatomical structure.
|For instance, add more clay to the body to create a fish tail. And
other objects can be used to create texture, for example I use a sea
shell to imprint a simple line pattern on the tail (figure 9). Finish
defining the head by adding and subtracting clay to define the eye and
mouth area if desired.
After completing the body and tail structure, use a wooden skewer to

After the bisque, you can apply glazes by brushing,
dipping, pouring, etc., to suit your own aesthetic. Whatever your
method of glazing, remember that applying the glaze is just as
important as the glaze itself, and where and how the glaze is placed on
the piece can enhance, emphasize or obscure particular areas. I like to
apply glazes with several acrylic brushes, a pointer to retain a high
degree of accuracy and several soft towels for applying and wiping away
large areas of glaze. I’ve found that wiping off the surface of a
freshly applied glaze with a towel allows the carbon from the
post-reduction process to partially enter the clay body, creating a
mottled effect. As a result of diverse glazing techniques, the ceramic
piece might have three coats of glaze applied next to an area that only
has one coat of glaze, or even an area that hasn’t been glazed at all.
As I apply glazes to my pieces, I take lots of notes and draw diagrams
in a sketchbook. By recording good notes, it’s possible to develop a
quasi-controlled outcome in the unpredictable firing process. For the
past several years I’e used five glazes. Three are from Amaco’s Old
World Crackle Series (Fog Gray, Amber and Satin White), while the
remaining two are recipes I mix in my studio (White Crackle and Copper
Matt.) All five glazes mature between cones 06-05.
I’ve been very
selective about my glazes because I want a wide variation of color, hue
and texture in my palette. I knew that the more glazes I introduced,
the less control I would have on the surface effects and I wanted the
glazes and alternative firing process to enhance my sculptural forms.
Through countless firings and a limited number of glazes, I’ve been
able to achieve a wide range of surface color and texture using the
variables of the glaze selection and application, firing temperature
and atmosphere of the kiln and the post-reduction chamber.
|After the bed of combustibles is made, place your piece in the kiln
(figure 12) and raku fire to 1600-1800 degrees F, depending on your
glazes. Using raku tongs and protective wear, gently grab the fish from
the kiln and place it in the post-firing reduction chamber filled with
combustible material (figure 13).
Note: Work in a well-ventilated
environment. Extra airflow is beneficial with the combination of Satin
White and White Crackle glazes over the ceramic surface. This rapid
cooling causes the glazes to shrink even more, allowing for more carbon
to reach the body and create large, bold black lines.
|Once the heat from the piece has ignited the combustible material, put
a tight fitting lid on the can to create the post-firing reduction.
After the can has smoked for a least fifteen minutes, remove the piece
and set it on a non-combustible surface to slowly cool. This is a very
critical time because your piece is extremely hot and fragile and can
break easily due to thermal shock. It’s imperative that you use a raku
clay body containing a medium grog and/or kyanite to withstand the
rapid cooling that takes place. So, never throw water on your handbuilt
piece right away; the uneven thickness throughout the clay body will
compound the stress caused by the sudden shock of temperature change,
and may cause the piece to crack or break apart. Instead let the piece
cool for another ten to fifteen minutes before “freezing” the color
with cool water.
|Finally, use a scouring pad or kitchen scrubber to wash away the
surface carbon (figure 14). I typically resist the urge to leave the
metallic color, even though it can be very attractive, and continue to
wash the surface to reveal an even more beautiful inherent coloration
with many tonal variations in the glaze and clay body under the surface
carbon. Experiment, test and have fun!
|My work has always considered
the many possibilities of inherent coloration through experimentation
with various applications of color and firing techniques including
raku, pit fire, gas kiln reduction, etc. By varying the application of
the versatile Copper Matt glaze, I’ve been able to produce a wide range
of color that’s very receptive to atmospheric changes inside the kiln
as well as outside the kiln during post-firing reduction. From
experiments with the application of the glaze, I’ve been able to get a
beautiful mottled surface with a gorgeous luster sheen and opalescent
color. In particular, I’ve discovered that applying less is better-one
thin coat of glaze that is then wiped off with a dry towel works best
to achieve a matt, speckled brilliant surface.
