ARRRGGHHH!!!!!!With no testing, and works on any clay body from cone 024
to cone 13? And I suppose you also want the glaze to fix any defects in
the pot's construction, right? Christmas isn't for another 9 months my
friend.

Mel, your post is wrong on so many levels, I'm not even going to start!
It's too close to NCECA to start tweaking us. (I see you grinning up there
in the frozen north, don't think I don't.)

And to think, before I realized what you were up to, I actually started
searching through my software archives to find you one. Fool me once,
shame on you fool me twice.....
Best,
Wayne
The only perfect red I've ever seen comes in a can labelled "Rustoleum"

Hi Mel,

I don't have the book handy right now, but if you have it, take a look in
John Britt's high fire glaze book. He has a glaze in there called Lab Fee
Red. Looks very bright, and pretty much a no-fail glaze, since it uses
Mason stain. I would think the color would stay fairly consistent, even if
you fired a little lower than cone 10.

BTW, I like your webpage. :-)

Take care,

Stephanie

One of my students has been experimenting with Lab fee red. It seems =
more like easter puke pink to me. Some students in beginning have been =
combining a copper green and temmoku and accidently getting brillinat =
reds.

Mel,
Back in 1999 Ingeborg Foco posted a series Ron Roy revisions to
Pete's Cranberry(^10), dated 22 Dec 1999. In that post he gave 4
different recipes along with his notes. My favorite is the RRRPR194,
adding .35 copper carb and 3.0 tin ox. It is a nice reliable red
glaze.

The Mayor sez:

>>i want a perfect , no fail, always perfect recipe. i want my

That is funny!

Of course you are going to get a perfect C10 Red from someone else that
is going to be perfect for you.

Ha! That will never happen on this planet. A perfect glaze passed from
one potter to another??? Good grief. What ambition! What nerve! What
foolishness!

Mr. Mayor, good joke. At least some of us got it. At least Wayne S. got
it.

Can we expect to be twitted again before NCECA? LOL

Hmmm...the perfect glaze....


actually...last summer I did stumble on the perfect
red glaze...for me....I mistakenly dumped a dry batch of
Pete's Cranberry
into a batch of another already mixed but 1/2 empty
pail of cu red glaze called Jeff's red.

I normally used one glaze over the other. the sum of
the parts of these is much better than either glaze was on
it's own.


I figured it was too many chemicals to waste so I fired it

cone 10 reduction ...started the redux at c 010

The glaze is just amazing...I still have about 8 gals left.
It's consistent... fires beautifully every time..no icky
greeny semi
oxidized spots from uneven reduction. Looks wonderful on
porcelain
not so great on stoneware.

I'll never replicate it...or at least I'm unlikely to
so I'll just use it and enjoy my mistake.

Anyone else ever have those serendipitous moments???

Also a practically perfect glaze I have used and have shared
with others
who sing its praises is one called CM White (c 9/10 ox or
redux.)

This one's been good for 25+ years now. Nothing fancy, just
the best white going.

Kathy


and...I don't want it named after me ......

I am just wondering what it is about my first name "Ingeborg" that makes it
sound like I am a he.
Please understand I am not upset. It is a routine thing for me and
constantly having to spell my name
several times over the phone. I get all sorts of mail and it is always
addressed to Mr. Ingeborg Foco, never MS or Mrs. I personally, just don't
understand it. On the other hand, my step father is named Bela, and many
people call him Ms. Bella which is the female version of Bela but most
people address him as Ms Bela. He is the least feminine creature I can of
think and I like to think I am not at all masculine.

So please tell me what it is about the American psyche that makes me,
Ingeborg, a man and my stepfather who is all hairy and well masculine, a
female. Just curious and not
upset but just wanting to understand. Since this is a friendly group and I
felt I could ask this question.

Best wishes

Sincerely,

Ingeborg,

Hi Ingeborg,

Sorry to hear you have such a problem with people recognizing your name as
feminine. Have you ever thought of using just Inge? If you had not said
it, I admit I most likely would have made the same mistake.

Most Americans do recognize Inge as a feminine name. Just a guess here,
but I think it's because it ends in a vowel. When people read names they
are not familiar with, they immediately (maybe subconsciously) try to
connect it with whatever they already know. If they see something ending
in an e or an a, that immediately sparks feminine recognition. If you
think about the most common names of people you know, very often (though
not always), girls' names end in a vowel - examples - Anne, Corynne,
Genevieve, Stella, Virginia, etc. It is more common for boys' names to end
in a consonant - examples, Michael, David, John, Albert, William...

Not to say it is correct, but it is common. Just my two cents worth. :-)

Mel,

It is so easy to get a copper red to fail. Wrong thickness, wrong schedule,
substituted ingredients.

Here are two reds I have used for some time.

HX Red (Hersioux Red)

custer 22.91
kona 22.91
whiting 10.93
flint 24.07
gertsley 14.17
epk 2.4
red iron 1.0
tin ox 1.0
cu carb .61

Hill Red (From Ceramics Monthly years ago)

custer 42.5
flint 26.6
whiting 2.7
gertsley 8.8
dolomite 8.8
barrium carb 8.8
zinc ox 1.8
tin ox 2.7
copper carb .4

I get all my materials from Continental, so there should not be any
substitution problems. I have tried the Hill red without the barrium and
without the zinc oxide. It is different without them. You can change the
red in the Hx red by varying the proportions of custer to kona.

My firing schedule is as follows:
red heat to cone 015 - oxyprobe .5 (in the neighborhood)
cone 015 to cone 06 (about 2 hours) - oxyprobe .7 (in the neighborhood)
cone 06 to cone 10 - oxyprobe .5 (in the neighboorhood)

Chris

Dan Semler on tue 6 mar 07


Hi Chris,

In respect of the Hill Red, you mentioned a difference without the
barium and the zinc. Can you expand on that ? Did you just remove the
barium/zinc (or one at a time) or did you replace or make up for the
lost fluxes with something else, eg. sub strontium or whiting ?

Could you describe what you mean by different ?

Thanx
D

Kathy McDonald on tue 6 mar 07


Thanks for posting this John,

Very similar to the recipe I have in my notebook.



Base glaze recipe is identical.

The additions are a bit different.


Additions:

Copper carb 1.00
Tin oxide 2.00

I have no idea why the variation exists
except that this recipe is from a workshop
that I attended in 1980.

Must try tests of both.

Following up on my original post, has anyone else ever tried
mixing two cu red glazes together. What would the
implications
for safety be ?

I now have a 10,000+ g batch of the mixture of the two
glazes.
The proportions would be by volume about 40% Jeff's red
and 60% Pete's Cranberry.

Should I use it on non functional items only?

Kathy

Lesley,

John Britt posted the recipe for Jeff's red.
and I reposted the small differences
in the one I have. My version has more copper
carb.


I am posting a picture of a plate with
the "mix" of the two glazes used as accent.

I took a picture of the glaze used as an overglaze
decoration and posted it:

The detail picture is likely the most accurate
representation of color.
