(Western
Style) Rakuyaki, or Raku, is a Japanese firing process. A bisque piece
is glazed with special raku glazes. It is fired in a small gas
kiln with a removable top. When the piece reaches maturity the top
is removed and the glowing white hot piece is moved via long tongs to
a trashcan full of combustibles. ie. newspaper, sawdust, banana
peals, leaves, bark... so on. The stuff inside the trash can
instantly bursts into flames and then the lid is put on the can and the
piece sits in the smoldering, smoking can. This causes the glaze to
change colors unevenly giving it a flash of colors. The unglazed
areas absorb this smoke/carbon and are turned black. White crackle glazes
absorb the carbon into the cracks making them visible. After the
pieces are cooled they are removed and gently scrubbed to reveal all
the colors! Please note that rakued
pieces are not food safe. Keep them out of direct sunlight because
the colors will fade. They are not water tight and should not be
used for planting.
You can take part in this fun amazing process by coming to the
KC Clay Guild's Raku Night! You get to
choose a bisque piece to glaze. We fire it for you and
you get to take it home that night! The whole process takes
about 1 to 1-1/2 hours. You
also get to choose a regular fired, already glazed, food safe piece
of pottery. While you are waiting for your piece to be fired, enjoy food and drinks
donated by local restaurants and guild members. When ever possible we also
have live music to entertain you while you are munching
on your snacks and waiting for your piece. We
also have a moonwalk, cotton candy and sidewalk
chalk to entertain the kids! Not only that, but
we will be giving away door prizes about every 30 minutes! Everybody gets
at least 1 ticket for a chance
to win. For the small fee you can't beat the fun
and excitement of Raku Night! If you have never been to one you have
to try it at least once! And If you have been before we'll be
looking forward to entertaining you again!

 Bisque
pieces are glazed using one of our many Raku
glazes.
|
 Then the
glazed piece is warmed up on small gas grill. This helps the
glaze dry too.
|
 Then the
kiln is loaded and fired up to 2000 degrees in about 30 to
45 minutes.
|
|
 Then the
kiln top is removed and the glowing hot pieces are quickly
moved to a trashcan full of combustibles.
|
 The newspaper
instantly bursts into flames and the reduction process begins.
This causes the colorants to seek oxygen and come to the
surface.
|
 This is a sample of what a Raku
piece looks like. Some glazes come out shiny in a rainbow of
colors and other come out matte. Some are smooth and some are
rough.

 This piece was
glazed with Copper Ridge. When applied thin and reduced just
right, you get a sandpaper texture with a matte rainbow of
colors. The thicker it is applied the heavier the
texture!
|
 These pieces
were glaze with White Crackle. Just 2 quick dips of glaze is
all you need. For a good crackle, don't put it in to the
reduction chamber too quickly. Waive it around in the air with
the tongs for about 15 seconds to let the glaze cool quickly,
causing it to crackle more.
|
 This piece
was glazed with Red Black Blue. It was reduced too long which
caused the whole thing to turn basically copper with some
pearlescent qualities. Had it been removed sooner there
would have been more color
variations.
