Hi Liz, and thanks :-)
How about celedons, are there spots that do it better? Do you think about
placement in the kiln on just the carbon traps, or other types of glazes
(besides copper red)?

I have a bit of temp unevenness in my kiln too, but the variation doesn't
seem to be a problem with the glazes as far as I can see. I have gotten
some incredibly gorgeous blue celedons and carbon trap shinos and copper
reds, all in the same firing. I start reduction around 010, and reduce
fairly heavily through the rest of the firing. I haven't really lightened
redux up much after the body reduction, as the kiln seems to climb in temp
steadily and results are usually nicest if I keep it in heavier reduction,
ie: more consistent reds throughout the kiln-load, and nicer celedons.
I have been most happy with a firing that is around 9/10 rather than 10/11,
although when I do go that high in temp, the glazes are still nice, I just
prefer the overall results when I fire a bit lower in temp,
Thanks again Liz!
Mishy, trying to enjoy the desert, even when it's 109F and drier than a
bone. Our water table is lowering, had to lower our submersible well pump
42 more feet, if it gets lower than that, we'll have to drill more- 450ft
down now....

Hi Mishy,
The carbon trappers go at the back by the flues, and on the bottom
shelf by the baffle and target bricks, and interestingly enough at
the top of the kiln, (C/11) where they get nice carbon trapping. As
a rule the celadons, chuns, and go in the middle and if I do have
rutile blues in there they go in the front by the door, where it is a
touch cooler. My celadon and chuns, like it to C/11, the tenmoku
like C/10, and I try to put them in the front half. Too hot, and my
tenmoku will run. I always scatter cone 10's and 11's throughout the
kiln to monitor it, and see if there is a difference with a different
stack. I don't use a copper red, and I too keep it in pretty heavy
reduction.
Well, kilns fire differently, and glaze recipes are varied, so Mishy
if you are getting good results with what you are doing, just keep on
doing it.
Best of luck, hope your well stays wet! mine dried up last summer,
(and I don't live in a desert, but we had a severe drought last year)
just a dug well, had it topped up. Let's hope for a nice rain every
once in a while.
