What are you using for a saggar? I've tried a hand made slab built, cone =
10 fired saggar, sealed w/ clay and fired to cone 02 in my electric =
kiln. Saggar filled w/ sawdust, oxides, salt, copper wire, etc {bottom =
exploded} but results beautiful.=20
I tried a commercial flur tile {12"x12"} sealed w/clay and kiln shelf =
etc, etc, with beautiful results but the flue tile broke in two ip the =
middle.=20
What are YOU using for a saggar?

Hi Greg,
Our best saggars have been evenly-thrown, deep bowl or planter shapes. Lids
can be another bowl-shape on top or a plate. Clay body--highly grogged raku
clay bisqued to 08 or 06.
When the inevitable cracks do appear, we repair the saggar with Sairset (a
brick cement). You just putty it into and over the crack. Even saggars that
have come apart in several places can be pieced back together with the
Sairset. (I think we have
some saggars that are more Sairset than clay :-))

I will be including some investigations in saggar firing as part of our
yearly summer raku course where I teach.
We will be doing the saggar firing in our Geil gas fired kiln.
I've done some saggar firings over the years, both in gas kilns with saggars
of bricks, old shelves, and handbuilt ones and in pit/sawdust firings.
I ran across this web site:
http://www.alexmandli.com/techniques/saggar_firing.html
The image shows a saggar using a chimney flue liner.
Has anyone used a flue liner like this?
How high did you fire?
How long did it last?
Just wondering if it would be cost effective to purchase some of these or
just build our own.

hi bill,
i've saggared in my electric kiln (itc'd) using the
flue liners you mentioned (they are terra cotta and
inexpensive, but if you can find fire clay ones, i
assume they'd be better!). i use a coil of clay (not
very thick) to make the 'seal' between the liner and
kiln shelves. i fire to 010. my program is listed
below (i'll probably ramp faster before and after
quartz inversion next time). the liners don't last -- i
sometimes still use the cracked ones and try to seal
them with paper clay (no, it doesn't really work).
Ramp program for Saggar 010
Seg Rate Temp Hold
1 80 180 6 hrs (7hrs) (to dry liner: damp basement)
2 300 900 0 (2.5hrs)
3 150 1150 0 (1.5 hrs)
4 300 1550 0 (1.5 hrs)
5 108 1632 0 (< 1 hr)
~12.5 hrs total
some of my results can be seen at:

click on gallery, click on saggar fired
hope this helps a little, and if you have more
questions, feel free to contact me. i never
have all (dang, not even 'most' most of the
time!) answers, but as they say: 2 heads...
