Firing Methods and Results
The process of Raku
firing differs from other firing methods because the pots are removed from
the kiln at their maximum temperature.
Thermal shock of this rapid cooling is
stressful on the pottery. It is achieved by using an open clay body. The
porosity of the clay body acts like a shock absorber, preventing the body
from immediately fracturing when the pot is removed from the kiln.
Raku glazes are often fractured, which are referred to as Crazing.
These crackle glazes are enhanced by the post firing smoking of Raku pots
that embeds carbon into the crackles of the glaze.
