The Raku Process
These tiles get their
irridescent effect from an ancient Japanese firing process called Raku. During
the process, the artist places the glazed piece into a very hot kiln. It remains
in the kiln for anywhere from twenty minutes to one hour or until the glazed
surface appears melted. While still red hot, the piece is removed from the kiln
and put in a bed of sawdust which then bursts into flame. After it
cools a bit, it is immersed in cool water.
When cooled, the piece is
washed with steel wool to bring out the full brilliance of the surface
It is the unique nature of this process that results in flashes of
copper luster for which the raku method is known. Because of the random nature
of this technique each piece will be special and one of a kind.
