For
those who are curious, I have summed up the process of how
I make ceramic flutes.
The
creation of a ceramic flute:
I
first form the bore using an extruder. I then insert the
wall inside the bore and form the mouth piece. At this point
I allow the clay to dry a bit before continuing to the next
stage.

In the next step, I cut the sound mechanisms into the bore
and continue to slowly let the clay dry. Once the flue and
fetish have been formed and the sound holes are correct,
I make sure that I have a good fundamental note.
I
continue to work the sound mechanisms, adjusting the sound
holes and the tone. Once the clay is leather hard, I then
do the pre-firing voicing. I take into account the shrinkage
that will occur during the two firings.

Next,
I continue by placing the tone holes and tuning them. At
this stage it is very important to take into account how
much the clay will change during the firings. Different
clay bodies either shrink or enlarge depending on their
composition and I have applied a lot of research to get
accurate results.

Now
it is time for the oven.

The
first firing is a bisque firing. After this firing, I again
adjust the tuning to make sure it will be correct after
the second and final firing. At this point, I have the tuning
just about where it needs to be for the final flute.
The
next step is the final firing.

Most
of the time I either pit fire or Raku fire the flutes.
For
pit firing, I place the flutes in a large open pit. I then
add various organic materials such as: woodchips, coffee
grinds, seaweed, banana peels and pine needles. After adding
the wood to create the fire, the pit is covered and the
fire is starved for oxygen. This creates reduction and the
fire looks for oxygen from the organic materials. The gases
that are expelled from the organic materials are what give
the flutes their unique and beautiful colors.
If
I chose Raku firing, the process is quite different. Raku
is a 400-year-old Japanese firing method that uses glazes
and reduction to create the beautiful colors you see on
these flutes. I use Raku clay to ensure the best results.
I then glaze the flutes using specific glazes for different
finishes. The flutes are heated up in a Raku kiln. Once
the flutes are heated to the correct temperature, they are
removed from the kiln and placed in a reduction chamber
where they cool down and their unique colors are created.
A
final tuning step, and the flutes are ready for their journey.
