Thanks for the cone 6 reduction glazes. Here a the glazes we've found work
out OK, and are currently studio shop glazes. We have noticed that a
slightly heavier reduction is needed for cone 6 than in cone 9/10.

Lith Carb............. 2.8
Whiting............. 8.4
Talc................ 11.2

I am getting encouraged from the responses. If you have any more cone 6
reduction glazes out there, I'd love to have them to try.

I haven't done any cone 6 reduction yet, but I have done cone 10 reduction using cone 6 glazes. Some were good and some weren't. I do mix cone 10 glazes with cone 6 glazes. You just have to test, test, and more tests.

Hi everyone,
Long time without so much as looking at the list...hello again...been busy.
Anyway, I was wondering if those of you out there might have some good cone 6
reduction glaze recipes stored away to give out. The high school I work at is
going to change over from cone 5 OXidation to cone 6 reduction over the
summer and change to all hand-made glazes. I've searched the archives and found
quite a number of glazes from 1996 through 2000, but who knows what changes and
revisions and new finds may now be available...I have Ferguson's Yellow written
down, thanks.
I'm not looking to get the list inundated with recipes...unless y'all want
that. I'm looking specifically for glazes that are fairly stable (as in don't
run all over the place) and mostly food safe. It would be nice if the glazes
were also fairly cost effective (low income school and all). Interesting hard to
find colors would be nice...I've already got about five iron red recipes,
several blacks, and a stack of browns to test.
A nice grey
A nice purple
A nice orange
A bright yellow would be nice...but I know it would be hard.
A reliable copper red
anything that might have a visually mottled look would be nice to test; I
have enough base glazes and simple recipes for matt, solid-colored glazes
I realize some of these colors are nearly impossible to come by without the
addition of expensive stains (which we cannot afford), but just throw it out to
me if you're willing and we'd greatly appreciate it.
Thanks, your all always a big source of help.
PS- if you do post recipes, would you mind also sending an extra copy to my
email
demjeffhq@aol.com
sometimes I miss posts that I really want to read because of the large # of
posts to the list nowadays.
thanks,
Jeff Tsai

Hi Jeff,
I posted the shop ^6 reduction glazes we used for 20+ years when I taught in
Montana State University in Billings. Many of those are going to be included
in Michael Bailey's new book on ^6 reduction glazes.
You may already have our black, iron reds, etc. So if you go back
to the archives, I also posted a good base glaze I called Marci's matt. It was
also listed in the Fire Place article in PMI Sept./Oct 2003.
I listed a variety of colorants with it in that article. You can also see the
results there as well.
Best wishes, Marcia

Lots and lots.
First, though, I should ask why you want reduction
glazes? Because reduction is what your kiln does
best (or all that your shared studio offers) and you
want glazes that will look good? Or because you
seek certain effects that can't be achieved in
oxidation?
Many glazes, of course, will work for both reduction
and oxidation, but some will look much the same
either way and some will differ. A 'specifically for
reduction' glaze is often just a glaze that looks
different if reduced than if not, being used in
reduction.
If it's reduction-specific effects you want, look for
glazes that get specific changes from reduction:
copper reds, shinos, temmokus, iron glazes, et al.
If you just want glazes that look nice in a reduction
firing, you can try almost any temperature-
appropriate recipe. Many of them will work well
in any atmosphere, though the result may differ.

Are there specific glazes? Yes and no. I've tried commercial glazes
that have no change that I can see in reduction and commercial glazes
that change dramatically in reduction. I'm finding things with blue
and green in them can become magical in reduction. The raspberry glaze
recipe in MC6 Glazes turns a magnificent melange of pinks and blues.
I've found the Caribbean Green (or Blue - I forget and my book isn't
handy) from MC6 Glazes turns a crappy black in reduction. I've found
the Coyote Clay Blue Oasis glaze is miserable in oxidation and
delightful in reduction.
There's a glaze called Panama Red (it's somewhere on the internet)
that is mint green in oxidation and deep red in reduction. And if you
do it just right, it's mint green on the flat parts, and deep red in
the incised parts. It's a great glaze for textured pieces.
Logan's translucent aqua (from Logan) may or may not turn maroon in
part or in total in reduction. Depends on where it is in the kiln and
how much of the stuff there is.
Reduction is great fun and I'm having wonderful fun experimenting.
Test like crazy. For me and the kiln I'm using, I fire to roughly ^5.5
(5 down and 6 starting to move). Then, I shut off the middle burners
and turn down the outer burners and leave things alone for 30 minutes.
An hour is too long. I fire reduction from ^08 through ^1. Then it's
oxidation up to ^5.5 or so. The hold is also done in oxidation. Then
everything is shut off, damper closed, peeps plugged, and let things
sit until cool.

Mel wrote in a message on kilns:
"diana pancioli has many modified recipes for cone 6 reduction.
bill burgert is firing cone 6 reduction in his small back yard kiln
and because of denver altitude, and low gas pressure he found
that cone 6, light reduction is perfect for him."
I would like to invite folks interested in cone 6 reduction firing to visit
Diana's website for a list of glazes to test. Here's her Glaze Forward page=
:
http://www.dianapancioli.com/downloads/GlazeForward.pdf
I would also invite you to visit my web site for a page of cone 6 reduction
glazes:
http://www.creativecreekartisans.com/creativecreek_cone6re.htm
At the bottom of the page, I have just added the latest named Ron's Fall
Yellow. Ron Roy was of great help in suggesting base formulas to get a nice
smooth mat. This was an attempt to recreate a yellow glaze we were using at
cone 10 and after months of testing, we finally got it to work.
Also, Dick White reports that similar effect can be had with this glaze in
an oxidizing firing.
