Raku pottery originates in Japan.
Specially formulated clays are used to produce a bisque fired animal with enough porosity
to handle the inherent thermal shock involved in the process.
Bisque fired animals are heated to nearly 1850° then removed from the kiln
and and red glowing immediately placed in a container filled with a combustible substance,
such as sawdust or straw or paper.
Interesting colors and crackle patterns are the end results,
due to various glaze formulas including metallic oxides,and materials that cause glaze shrinkage,
yielding the crackle patterns' or causing the metals to turn to a rainbow of different colors.
All the colors are natural metal colours that are brought out by the fire and heat.
Every animal has it's own personality,because the heat,flames,and colours are always different.
