impossible to make and fire in two days?

updated sat 12 feb 00

 

Anita & Nick Feng on mon 7 feb 00

Is it at all possible, in any way, style or form, to do a hand-building
workshop on a Saturday and be able fire a few results on Sunday? Magic clay
body? Special formula for pit-fire or raku? Or just a dream?

Thanks.

Hi,
I do a thing with school teaches to show them how to do pitfires.
9AM Quick demo of coil techniques and slip.
11:00 They must be finished, load pots into a bisque kiln set to keep it at
around 165 degrees
3 PM load bonfire firing.
4 PM unload bonifire firing.
I use a commercial raku body that I add coarse grog to.

I also do a demo and firing in my first day of class in Beginning Ceramics.
First we pinch a pot, then glaze the interior, then we load them into the Raku
kiln and i set them to dry out, slowly turning up the juice until I can pull
the pots out fifteen before the end of the 2 hour 50 minute class.
GGROGGGY Clay.

Anita,
Sometimes I do a "quick" experimental piece and then place it in a drying
oven which consists of a base board a large plastic bag and an old fashioned
hair drier which had a tube going to a cap placed over the hair.
I staple the opening of the bag to the base, cut a slit vertically which is
then the opening for loading and cut another small hole in the bottom of the
bag to tape the tube into. I then tape around the base of the board to seal
the joint between the bag and the board.
I load the work into the "oven" seal the slit and switch on the hair drier.
When the bag pumps up I punch a few holes at the top to allow the moist air
to escape.
This method gives me a quick and even drying out of the pieces and it can be
ready to raku the next day. Incidentally when you put the pieces in put
something in to act as a deflector so the air stream a) is forced to spiral
around the bag and b) does not directly blow onto the pieces,. A brick will
do. I think this could be adapted to modern hand held driers but you would
need to protect the bag from melting near the outlet of the drier.
Experiment if you can Highest heat setting may not be the best (too sudden).

Feri.

Limitations: I've never done this with more than three pieces at a time any
thing more than 1/2 inch thick may take a lot longer to dry out.

Anita -
For raku and bonfiring here at the Craft Center and for my Ancient Clay
workshops I use a claybody which is equal parts goldart, fireclay, ball
clay, and extra fine grog. It is a joy to use, and it can be dried very
quickly in a warm kiln. It has very high thermal shock resistance, and
works great in raku and bonfire. It is also a great high-fire sculpture body.

In my Ancient Clay workshops we make wares with this claybody right up
through Thursday afternoon, bisque-fire overnight, and then bonfire on
Friday morning. If you do a raku single-fire you can do it even quicker,
but you would need to bring the raku kiln up to temperature much more slowly
if the wares have not been bisqued. I'd rather bisque in a nice even-firing
electric kiln, and then be able to glaze bisqued wares. Then you can raku
fire them immediately, as long as you do not put freshly glazed wares in an
already-hot raku kiln.
Good luck -

This looks like a job for PAPERCLAY!!!!! Have a look at Rosette Gault's
book.

John C. Campbell Folk School in Brasstown, NC has a really neat
"warming" room. Basically a big closet with shelves and strip heaters.
For the workshop I attended this was how we forced things to dry
quickly. You might want to contact them.

Vince,
What color is your clay that is equal parts goldart, fireclay, ball
clay, and extra fine grog, before and after firing?
Thanks,
Nan Kitchens

Hi Anita
I teach children's classes and sometimes have to dry work rapidly. I
created a drying room in a small bathroom with a 5 shelf bookcase in it. I
have a small heater and dry the work in a few hours. I usually have the
children make pieces that will be fine with forced drying. This set up is
in my teaching studio.
At my home studio which was built in the 50's, I heat with radiators. I put
a table in front of the heater and make a tent over the heater and the work
sitting on the table with a blanket. It becomes a great drying area when
needed.
I also have the kids make slab work and put the pieces on drywall and it
dries quickly.
Hope this helps!
Good Luck!

I did a kids class one summer where I fired every day. The secret is your
selection of items. Must be thin walled and of such a size as to not be
crack-prone (large tiles are out, small tiles are fine) Used terra cotta and
heavily grogged sculpture clay. Can't imagine raku clay wouldn't work fine.
Dried things on top of the hot electric kiln for the next day's firing. One
night, my home oved was full of things, too. Fired some things dampish, just
gave them a few more hours at the front end with a lid 2" open.

The Paragon QuikFire 6 and Evenheat Rapidfire can fire
a small ceramic piece in 50 minutes. I've made glass
fused pieces in 40 minutes, from initial firing to
finished piece, cooled to room temperature.

I tested QuikFire prototypes when Paragon first
developed the kiln and destroyed several by heating
beyond 2,000 deg. F. That taught me that over-firing
one will burn up the element.
