Traditional raku techniques normally use
some type of organic
material to affect the visual outcome of
the work during the firing process. Materials such as sawdust, dung,
dried leaves, etc. are often used to
impregnate the clay body and make it change
in color and effect.
Smokeless raku is a technique, which
eliminates the organic materials, as well as
smoke, yet provides similar surface finishes
as smoking. This technique is a great asset
for practicing raku in confined locations
where smoke would be not be tolerated. The
key to smokeless raku is the use of
“denatured alcohol”. This replaces the use
of any type of organic material.
Important to this approach, however, is how
the post firing system is set up and
operated in order to get the best result
with alcohol usage.
