A friend of mine in Missouri who is far from any affordable on-line access
asked me to put a search out for a lost glaze. She calls it Cobalt Green,
is cone l0, "almost black green satin matte" found in Ceramics Monthly
several years ago(a search through my collection did not turn it up), uses
cobalt and rutile and may have been under the questions section. If this
rings a bell with any one, could you please send it to me or the whole group
and I shall send it on to her via snail mail. Thanks a bunch.

Barb,
I think the glaze you're looking for is called Reitz Green. The recipe printed
in CM was a variation that included:
Nepheline Syenite 70
Petalite 15
Gerstley Borate 2
Whiting 5
OM4 8
Add: Cobalt Carb 1
Rutile 2
I've had some difficulty with heavy iron bearing clays, however, I have used
them only rarely and don't know for sure it was the clays. A white/buff clay
works best.

I'm hoping that someone may have this recipe because I've lost it and =
can't find it anywhere in my notes. It's a cone 6 glaze, an iron red, =
called Red #3. If I remember correctly, there was Gertsley Borate in =
it.

Hi Marianne,
This is the only Red #3 I have in my records, but has no GB. Hope it is t=
he
one you are looking for.

Glaze test for William Edwards' Red #3=A9 , cone 6, oxidation.
Tested on light, mid-range stoneware, with iron flecks. Fired to 1220c
(2228f) oxidation, at this ramp:
100c to 600c 212f to 1112f
150c to 1100c 300f to 2012f
100c to 1220c 212f to 2228f
soak at 1220c for 30 minutes =
cool down 100c per hour to 900c (212f/1652f) =
soak at 900c for one hour
shut off and cool down (aprox. 40 hours)
Recipe
24 3134
10 Neph. Sye
16 EPK
20 Whiting
26 Flint
2.5 Talc
1.5 G200
ADD
5 Tin ox.
0.35 Chrome oxide
Subs: =
Frit 169 for 3134
Forshammer for G200
Resulted in a smooth gloss glaze, with an underlying grey to pink fluid
colors under gloss "shell". Some signs of burgandy where thickest at top=
of tile. Stayed where dipped and no discernable difference where thicker.=
I
believe like the Rosenrot, I should let this glaze soak longer before usi=
ng
to get the deep burgandy. However, it is quite understated and nice on
this test.

We had a glaze that we called "Rich Oriental Green" in our studio.
Unfortunately, it and the other recipes on the same page have vanished.
This was one of our oldest glazes, and was around before our current studio
manager arrived. (about 8 years)
I am currently in the process of looking through all old CM magazines, (I
just finished the 1950's archive on CD) trying to find this recipe.
It's appearance is very similar to Korean Celadon. I believe that it has
about 5% RIO in it. It is a dark olive green glaze that breaks beautifully
over texture. Where it is thin, it has a deep rust color, where it pools,
it appears nearly black.
We think that it came out of CM, but we're not sure. Has anyone else heard
of this glaze? Can you point me to where I might find it or something
similar?
Thanks for the help
Beth
