Dear Angela:

I am willing to bet $$ that there is bone ash or some other source of
phosphorus in that glaze.

Hope you come up with it eventually.

Cheers, Hank in Eugene

Heres my sad story. A student in our adult class brought
a couple buckets of glaze she mixed up in a previous pottery
class. It is a really nice cone 6 that is very dark blue/black
when thin and a nice red when thick. Breaks beautifully
over texture. I have a couple photos on Flicker...

She called it Jen's red but I have not found any reference to
a glaze with that name. She told me it was from a recipe but
was never able to provide it. I am thinking it may be a premixed
dry glaze. I have seen Jensen Red mentioned and found it sold
by Aardvark but it is a cone 10.

I would appreciate any information about this glaze or one like it,
it really is nice.

Some of my students have had results like that with Randy's Red,
depending on the clay body, application thickness and whether their
piece was in a hot spot in the kiln. It can really vary widely.

Hi Angela:

You glaze looks quite a bit like one used in our community studio called
Randy's Red.
I believe there are recipes for it on the internet and I'm sure there
are
other's on clayart that have it available.

Heres my sad story. A student in our adult class brought
a couple buckets of glaze she mixed up in a previous pottery
class. It is a really nice cone 6 that is very dark blue/black
when thin and a nice red when thick. Breaks beautifully
over texture. I have a couple photos on Flicker...

She called it Jen's red but I have not found any reference to
a glaze with that name. She told me it was from a recipe but
was never able to provide it. I am thinking it may be a premixed
dry glaze. I have seen Jensen Red mentioned and found it sold
by Aardvark but it is a cone 10.

Thanks Hank, I won't take that bet, can't afford to lose. But thanks
much for the support.

I have had some great responses from some potters I greatly admire.
2 have said it looks just like a glaze from Minnesota Clay, HG5 iron red.
So I have ordered a batch of the dry glaze.

Another wonderful potter said it looks like Randy's red or a variation
called plum.
I have those recipes and will mix them tomorrrow to test.
When I get all the results together I'll share them here.

Thanks everyone for your help and if any still have some ideas I'm open to
hearing
them. Wish me luck!

You might compare the glaze to this one at Dakota Potters supply.

Somebody answered you that it might be Randy's Red. There is also a
Jan's Red. Jan's Red is close to Randy's Red.

The Randy's Red (Cone 5-6) I have is:

Silica 30
EPK 5
F-4 Feldspar 20
Talc 14
Gerstley Borate 32
Soda Ash 10
Red Iron Oxide 15

This adds to more than 100.

The Jan's Red (Cone 5-6) I have is:

Silica 20
Custer Feldspar 14
Talc 9.5
EPK 3.5
Gerstley Borate 28
Red Iron Oxide 15

This adds to less than 100.

I usually use the Jan's Red. Reliable. I don't get the variation you
are looking for because I usually put and even amount of glaze on.

Check Ceramics Monthly . In the year 1996 (I think) there was a page of Cone
5 or 6 Iron Red glazes. One of those is used by a Minnesota potter who sold
me a bowl at Cherry Creek that is a ringer for your mystery glaze. Maybe
someone on the list has that page. I used to have photo copies and mailed
them all out. I thought I had it on the computer but couldn't find it. I
think I sent to clayart once but haven't tried the archives. I remember one
of the ingredients had the number 44 in its quantity and I think none of the
other glazes on the page had that number. It was in the middle of the page
I'm pretty sure.

Here is a link to an article that illustrates Hank's point and even has a
glaze with 44 grams of Custer Feldspar, but I am sure the glaze I have in
mind has Gerstley Borate in it.
