Does anybody have some experience with putting salt in a saggar firing?
I am interested in trying this, but if it's gonna be a waste of time and
space, etc. I'd rather not.
I'm thinking in terms of placing a pot inside the saggar with
combustibles and either table or rock salt, firing to ^6 electric.

Lisa, do you regularly fire a saggar in your electric kiln? What are the
problems with combustibles, (especially in a basement firing). TIA

Hi Lisa;
I did this as an experiment in one of my college ceramics classes. I used
a buff stoneware clay (fairly smooth) added salt to the saggar and if
memory serves, some banana peel. Glazed the inside of the pot with a honey
amber glaze. I made sure I sealed the saggar as best I could with
fiberfax. The result was a fairly pleasing light glaze that looked almost
clear with a slightly pebbled surface. I did a little brushwork on the
bisqued surface with cobalt oxide mixed with a little water. This however,
faded out almost entirely. For more color you might want to add colorants
(copper carb. for instance) or use a clay with more color (iron oxide
whatever). This would probably produce a warmer color. Its worth doing if
only for the sake of experiment and new experiences. I'd like to do it
again maybe using cone 6 porcelain and a wider variety of combustibles in
the saggar. I read an article in an old ceramics monthly in which the
artist had used low fired saggars and produced from what it sounded like
more color as a result.
At the same time I did a saggar firing in the colleges gas kiln.....using
copper carb., seaweed and steel wool draped on parts of the pot...with a
shino liner. This was a cone 10 firing and except that my saggar split
(because I had used a mid range stoneware clay instead of a high fire
clay)...was a more pleasing result. Faint blush of pink on one side but
not enough salt from the seaweed to produce a all over light glaze coat.
I was however, quite pleased with both pieces and they generated a best of
our class of '94 in Canadas' Contact magazine. (They were doing an article
on graduating classes across the country).
Experimenting with new techniques and ideas is something I definitely miss
since finishing these classes. The teacher was definitely inspiring and
generated a feeling of "why don't you try it and see what will happen'
attitude.

my response is prefaced with: i am a beginner but this is some of what i've
done during a "primitive firing" workshop...
materials used inside a saggar pot either on or around the ^012 fired bisque
ware:
*straw soaked in a salt brine
*baling twine soaked in a salt brine
* organics : beets & brine, onions, etc (can't personally account for their
affects)
* kosher salt
* "sulfates", cobalt, iron and copper in water
the saggar pot enclosing the to be saggar fired pot were fired in an converted
electric kiln fuled by propane gas to about 1500 degrees
the results are rich in browns, blues and reds
any questions ask me...Grace

the saggar firing i've been involved with is done outside as the fumes are
great and not good for breathing !
