From 16th century methods founded in Japan
to the 20th century reduction methods of the
West, raku has always revealed exciting
and dramatic results. Mayco Raku glazes
produce a variety of metallized, brilliant
and crackled finishes. All glazes are non-toxic,
formulated using no added lead or other health
We recommend using a thermal shock-resistant
Raku clay body (will help reduce the incidence
of cracking). As glaze application, glaze fire
temperature, combustible materials, firing process
and kiln type vary from artist to artist,
final results will vary. Our product testing
involved a Raku clay body, Raku kiln and straw
for our reduction material.
Raku can be done in a gas or electric kiln
environment as well. Maturing the glaze at
lower temperatures and using different combustible
materials such as sawdust, newspaper, straw
etc., will greatly influence the colors and
look of the glaze. Minimizing the distance
between the kiln and the reduction container
will also enhance color.
Proper safety processes and personal protective
equipment are very important when doing Raku as
you are exposed to high heat, flames and smoke.
Always wear heat and fire protective clothing
and fireproof gloves. Do not open or insert tongs
into an electric kiln without shutting off.
Reduction process should take place outside
of building due to flames and smoke.
