Hi,
Someone asked whether saggars were usually done to higher temperatures, like cone 6/10. The answer is, to my knowledge, not usually nowadays. Nowadays, in the United states at least, Saggars are done to lower temperature (saggar not simply in the sense of ware in a box, but ware in a box with colorants and the hope of fumed colors.) The colors tend to be richer and more variable at lower temperatures, ranging from cone 018 to 04.
I believe high fire saggars is how saggar firing originally started in the Asian countries, but I don't know enough history to tell you time or place or origin. I have seen high fire saggars even today, but they seem rarer.

Jeff,
Many years ago at Massart .......around 1976+/-)...... I started teaching=
a
course I developed called "Fire Painted Clay". It involved a number of
fire induced surface treatments as part of the curriculum. High
temperature sagger firing (cone 10) was one prime component of that cours=
e.
I've been doing some HT sagger firing since then. For the past 6 years =
or
so at NH Institute of Art I have been teaching a course solely focused on=
high temp sagger firing.
You are correct........ not too many people do it...... but it IS happeni=
ng
"out there". I have seen other HT sagger work in shows.
BTW........ the color pallete is much broader than you think.
Best,
..............................john

Went to a Byron Temple workshop a few years back. He mentioned that he
puts a saggar in every high-fire gas reduction kiln he fires. Also said
that in recent years he had switched from sawdust to chopped up charcoal
because of getting better color with charcoal. ---gail

Hmmm. This raises some questions or me. Saggers aren't absolutely
airtight?
right?
If they contain most but not all of their aerosol soup, does a little
leakage from
the
sagger effect other pots in the kiln? Does sagger placement (say, very
close to
the
exit flue) minimize any problems?
Clearly this interests me. High fire clay bodies and vitirification *and*
sagger
fired effects. Wow.

I have fired high fire saggars since meeting Byron Temple in 1976. Stopped
doing it
about 3 years ago when I had to give up my reduction kiln. I never noticed
any effect
on other pots but must confess that I usually put the saggars near the flue
opening
where I had a cool spot. Suspect they went slightly above Cone 9 and any
escaping
smoke went directly up the chimney. Mostly I fired porcelain clay as I
liked the
smoking of the porcelain better than that of stoneware.
Now you have me thinking about trying a small saggar in the electric kiln
with the
direct vent system. With plenty of ventilation in the garage of course.
I'm not
worried about the elements as I'm moving soon and plan to buy a new kiln
with a
controller.
There are some John Leach saggar fired pots at this URL. If you do an
internet search
you may find more.

Jeremy, do some tests and have fun.. Let us know your results.

Dennis and Jeremy,
Now that I remember more, I recall that Byron said he placed his saggar
near the flue also. ---Gail
