hi bettie
i do microwave raku
for the last several years i have perfected a technique to speed dry pottery using
the microwave
this was my response to bemg able to include pottery as a day or weekend workshop
at esalen institute, big sur, ca
i make coarse raku clay bodies that will dry in the microwave in 5 minutes to
several hours and then into a kiln for a bisque fire...the pottery can be pulled
out at peak bisque temp, without waitning for a cool down
i have also been able to take a pot out of the microwave and into a cone 05 kiln
instantly for a 5 min firing
in all i can make a wet tea bowl wet glaze, microwave, and fire and glaze all in 15
minutes
i call this microwave fast food raku
i conduct weekend and day long workshops that have included from 10 to 25
participants and over 70 pieces all dried, fired, and glaze within 24 hours, with
no losses, and then have a tea ceremony
my next workshop is april 21,22 near osaka, japan
there is no other secret...do the wave

Hi,
Is there anyone who knows about making raku with the microwave??

Yes,=20
I use to make pots at the weel every chrismas using:
Kebab-meat or/and minced meat and "bake" them in the microwave-owen. =
Kids love
to eat potts!
Other materials: gingerbread-dough or marzipan works well too.
Not Raku but good!

Hi Bertie,
That's Ragu, not raku....a spaghetti sauce for pasta, and yes, you can
do it in the microwave with the rest of the leftovers.
Cheers,
Harvey Sadow

Hi all,
Yesterday I had a phone call from a research worker in British Steel

Noel,
Thanks for this interesting post. I (for I) would be interested in such info
as the heating protocol, the power of the unit, whether pieces need to be
moved around (on a carousel?), how the capacity of the oven is determined,
and how load affects heating protocol. Thanks.
Best regards,
Jim Mason,

Hi, there - At first I thought, by the subject line, that someone was
actually rakuing in a microwave! Of course not---it doesn't get nearly hot
enough. Then, upon reading further, I discovered that this person is just
DRYING the stuff in the microwave---this isn't the first time I've heard of
that. The person who used to do my firing when I first started potting
would ocassionally fast-dry something in the mike in order to get it into a
bisque firing right away. I have made many small items for rakuing and
regular firing and immediately put them into my regular oven, at 250F or
300F and fast-dried them, then bisqued them later that day. As long as you
get them into the oven while they're still damp all over, it works. If
they've started to dry on the outside, they'll usually break. I've only
done this with smaller handbuilt (pinched or slab) items, and they don't
have fragile or complicated attachments. This is a desperation technique,
used with a "what have I got to lose?" attitude.

Could someone who's done this please post some more info, such as how to
determine how long to keep a piece it? How much breakage do you get and how
to prevent breakage?
The note about putting it in fresh was helpful, but my first piece I tried
(very small vessel) broke after a few seconds.

I had the same experience and DO NOT RECOMMEND IT FOR SERIOUS POTTERS.
