To fully understand the Raku Firing Process, one would have to delve into and study Japanese culture. Raku is deeply
associated and intertwined with the ancient Japanese tea ceremony. Serving and drinking tea using Raku fired bowls is
an age old “happening” that is still performed in some areas of Japan. Tradition, religion, attitude and philosophy of life
are all integral parts of the process.
The Raku Firing Process involves a special kiln, that can be raised and lowered over the pieces to be fired. Raku glazes
contain a lot of copper that gives the fired pieces: green, red, blue and copper shades. The temperature is rather
quickly run up to about 1800-2000 degrees F and then the kiln is raised, revealing red hot pieces standing there. The
piece then placed in a bucket containing combustible materials. As soon as the red hot piece comes in contact with the
combustible materials, spontaneous combustion occurs. The lid is put over the can tightly in order to make reduction
atmosphere and let the flames seek for the oxygen removing it from the glaze and clay body of the piece. The result is
black clay body and very interesting colors on the piece. Depending on the type of combustible materials, the glaze
composition and the time in the can, no two pieces of Raku will ever be the same. It 's like Christmas! After the piece is
removed from the can and sprinkled with water and the colors are then “set”.
Raku ceramics by their creative process and their very nature serve only for decorative purposes and are not intended to
be used for food or tea !
