Good morning all.... I'm searching for a glaze that I've seen
called Emerald Green. ^6 and is a high gloss at ^6 and a matte at ^4 or ^5
... I have seen the glaze Mexico green and Sana Green posted.. I've been
testing,,, but nothing comes close .. Surprisingly, Floating blue is
compatible with this glaze and doesn't go green.. just does it's beautiful
blue where thick.. I've only been with CLAYART 1 week.. so I apologize in
advance if this is a common glaze.. Thanks so much, gracie

Hi Gracie and everybody else. Here is a glaze that came out Of CM in 6/87
if my notes are correct. I hope it is a good solid glaze because I have
been using it since then.

Emerald Gloss Green ^6 ox., but is shiny even at ^4

We use a glaze called Emerald Green at the art school where I take
throwing lessons. I don't know how it does at ^4 or 5, but at ^6, it
is a beautiful, glossy, transparent green that pools in ridges or
incising, and has a 'near blue dark green' where it is very thick.
It is a bit finicky, settling quickly, so we stir it when ready to dip.

This is the recipe I was given, and it makes enough to do about 5
gallons at dipping viscosity (amounts in grams):

Emerald Green
Cone 6 - Oxidation

Nepheline Syenite 3750
Talc 2700
Whiting 1600
Colemanite 1050
Kaolin 800
Zinc Oxide 100
Copper Carbonate 500

I would welcome any comments on ths glaze. It is one of my favourites,
and I'd really like to do a blue version, but have no idea if it's even
possible.

Hi Larry,

I'm not Ron Roy, in fact I'm just starting to understand glaze
chemistry, but when I put your recipe into Insight, results suggested
that alumina and silica are both low in this glaze, and with the
amount of copper, there's a good chance that copper would leach if
the glaze is in contact with acidic foods. Magnesium is somewhat
high, but I don't really know what the consequences of this would be.

I tried a revision just for fun, adding some kaolin and silica to
bring the amounts up within the limit formulas, but I don't know how
it will look. By the way, the extra kaolin should also help the
settling problem (caused by all that neph sy) as well as making the
glaze harder and more durable. I also subbed Gerstley Borate for
colemanite, since that's what I have. As for a blue version, with
this much magnesium, you might get purple -- I just tested a
high-magnesium glaze like this and got real, honest to goodness
purple with additions of 2-3% cobalt carb.

Anyway, here's the revision, if you want to try it -- I will too,
just for fun and because I'm looking for a good dark green.

Emerald Green revised

Nepheline syenite 25
Talc 18
Whiting 11
Gerstley Borate 12
EPK 13
Silica 20
Zinc Oxide 1

Copper Carbonate 5

Hi Larry,

Your Emerald Green glaze has some potential problems using accepted limit
formulas. With boron treated as a stabilizer (not in unity) it
calculates:

K20: 0.034
Na2O: 0.112
CaO: 0.418
ZnO: 0.023

Al2O3: 0.221
B2O3: 0.139

SiO2: 1.394

Silica is the problem. Normal limits for silica for a cone 6 glaze are
2.5-3.5. This could cause the copper to be very leachable. It could
also be easy to damage physically. If it were my glaze I would
definitely test it for copper leaching before putting it on food
surfaces. Limit formulas aren't perfect predictors so it may test OK.
If you decide to do that, let us know the results. By the way,
substituting Gerstely Borate for Colemanite doesn't change it enough for
me to alter what I said above. John

series of hobgoblins, all of them imaginary." H.L. Mencken, 1925

Andrew Buck on wed 9 dec 98

Larry,

The Emerald Green glaze that you sent to the list is very easily changed
to a blue glaze by substituting cobalt carbonate for the copper carbonate.
Cobalt is a much stronger colorant than copper, so you will need to
decrease the amount of used.

If you add up the weight of the first six ingredients of this glaze you
will end up with a batch weight of 10,000 grams. In the case of this
glaze, the first six items are what is know as the "Glaze Base" and 10,000
grams is a very typical amount to mix at one time because, as you noted,
this amount usually fills up a five gallon bucket to a usable depth.
This base glaze, I would guess, is a shiny clear glaze, by itself, without
adding a colorant like the copper carbonate. To figure out how much
cobalt to use in place of the copper, first you will have to figure out
the percentage of copper that was added to the glaze base. To calculate
the percentage you divide the amount of copper carbonate to be added to
the glaze base (500 g.) by the total weight of the batch (10,000 g.) which
gives you a ratio of colorant to base. Then you multiply the ratio by 100
which gives you the percentage.

Example: 500 grams / 10,000 grams x 100 = 5.00 percent

I think you will see another advantage to 10,000 gram batch recipes below.
It is very easy to tell what the percentages of all the materials in the
glaze are without doing a lot of math.

Emerald Green Cone 6 - Oxidation
3750 Nepheline Syenite...... (3750 / 10,000 x 100 = 37.50 percent)
2700 Talc................... (2700 / 10,000 x 100 = 27.00 percent)
1600 Whiting ............... (1600 / 10,000 x 100 = 16.00 percent)
1050 Colemanite............. (1050 / 10.000 x 100 = 10.50 percent)
800 Kaolin................ (800 / 10,000 x 100 = 8.00 percent)
100 Zinc Oxide............ (100 / 10,000 x 100 = 1.00 percent)
10,000 grams Batch Total (10,000 / 10,000 x 100 = 100 percent)
Add:
Copper Carbonate......500 (5 percent)

Now to determine how much cobalt carbonate to add to the base recipe you
will have to do a little experimentation. My books tell me that adding as
little as 0.2 percent will make a glaze take on a noticeable blue tint and
that the usual range of addition is between 0.5 and 1.0 percent. You will
have to mix up a small test batch to find out how much cobalt is needed to
give you the blue that you want. The more you add, the bluer it will get,
until you get so dark that it looks almost black (over 1 percent, most
likely). Make up some test tiles or small pots to test the glaze on (make
sure you number the tiles or pots some way so you can tell one from the
other after firing) and try mixing up a 1000 gram batch of the glaze base
as follows:

375 g. Neph Syn
270 g. Talc
160 g. Whiting
105 g. Colemanite
80 g. Kaolin
10 g. Zinc Oxide
======
1000 g.

Add 2.5 grams of cobalt carb. (0.25 percent of the batch), mix and apply
to a test piece. Add 2.5 grams more cobalt (total of 0.5 percent of the
batch), mix and apply to another test piece. Repeat this process two more
times for a total of 10 grams of cobalt added (1.0 percent of the batch).
Fire the pots and take your pick of the best results. Now you have blue
version of a glaze that you like and you are on your way to being the next
Clayart glaze guru. 8^o Happy testing.

Do you mean damage as in chipping of the surface?

Oops... too late. :-)

Seriously, I'd love to test it. Can I do so without being a chemical
engineer, and without accidentally manufacturing nitroglycerine or
hydrazine?

As a reminder, I've attached the instructions for having glazes tested
for leachable metals for anyone interested. These can also be found on
Tony Hansen's site (digitalfire.com) or on my site (see below))

I've received some requests for information on how to have glazes tested
for extractable metals at the Alfred Analytical Lab. It is really quite
simple and inexpensive and we should all thank Monona Rossol for working
with Roland Hale at Alfred to get this set up. Here are the details.

1. Make a small cup (mug size or smaller--I use about 300 grams of clay),
glaze it and fire it at your standard conditions. I usually put a cone
pack right next to the cup so I will know exactly what temperature it saw
during firing.

2. Send the cup to:

Dr. Roland Hale, Director
Alfred Analytical Laboratory
4964 Kenyon Road
Alfred Station, NY 14803

3. Enclose a letter specifying what to test for and a check (U.S. funds)
based on the following fees:

There is a standard $10 fee per sample to do the acetic acid extraction

Add $10 for each metal you want analyzed

Example: Analyzing a single sample for lead, copper and cobalt would cost
$40.

If you want your samples returned there is an additional fee for shipping
and handling of $15 per order.

4. If you send multiple samples make sure they are well labeled so you
will know which result goes with which sample.

5. In 2-3 weeks you will receive a written report on your glaze. This
laboratory is a New York State approved Environmental Testing Laboratory
and your report will come on letterhead stating that. I have found
Roland, and the others in the lab I have talked to, to be extremely
helpful and courteous.

6. While there is no requirement that you send the glaze composition or
firing conditions, Roland would appreciate it if you would. He is bound
by state law to keep the information you send confidential unless you
specifically release him to disclose it. However, Roland is developing a
data base of the samples tested and will try to extract from that
information which will be useful to potters in developing leach resistant
glazes. He can do this on a unity formula basis while still maintaining
confidentiality of specific recipes.

Any questions? Call the laboratory at 607-478-8074 or fax at
607-478-5324.

Dai Scott on thu 10 dec 98

Regarding the percentages (Judith's) of the Emerald Green glaze
(Larry's)---if the base recipe equals 10,000 grams (as I read it) then
shouldn't the percentages be:
Neph Sy 37.5
Talc 27
Whiting 16
Colemanite (G.B.) 10.5
Kaolin 8
Zinc oxide 1

Add: Copper carbonate 5

Also, my understanding (slight as it is regarding glaze formulation) is that
food-safeness and durability isn't dependent on the recipe adding up to
100%, but rather on the ratio of each ingredient to the others within the
recipe. Am I way off base?

Glad to be back home after a trip across the Rockies to Calgary for a
wonderful show last weekend---and the roads were great!

Thanks, Chris, I'll mix up a batch as soon as possible, and give it a
try. I'll also pass it on to the fellow who mixes the glazes at the
community art center. The main thing I want to preserve about this
glaze is the wonderful transparenc of it, and the way it pools dark in
the grooves.

Thanks a lot for offering another glaze formula. I didn't really mean I was looking for "simple" glazes. What caught my attention was that your glazes resemble a look I use already. I want the students to have an appreciation for glazes with texture, depth, and color variation. I just need a few more formulas to try-because we don't plan to buy any commercial glazes this year.

For example, I can achieve interesting effects with a dark oxidation body, then layering a cream and a cobalt colored glaze that has a little granular rutile in it.

The glazes the students have trouble with are mostly the reduction-look commercially prepared glazes called "Opulence." We also need to save money and therefore plan to mix all of our own glazes. With these glazes, the color is nothing like the catalog shows unless they are applied really thick. Then they tend to flake off the pot before they are even fired.

I have more than a dozen really stable interesting glazes that I have developed on my own over the years. I just need a few more to use in layering so I can stop buying the ones called "Opulence." I will try and put a few pics on the Clayart spot on whatever that picture site is called.(Flickr I think)

If I had the formulas for Raven Wing, Mountain Mist, and Rose, I think they would work nicely with the teal, cobalt, cream, gray, turquoise, black,etc. that I already have. I fire at cone 5 or 6. Of course I would never in any way try to copy your look. As I mentioned before, it is that blended, textured look that my students have already grown to appreciate.

Thanks for your input- Sally.

Sally,
We would love to help and will go through our recipe book but most of the
glazes we use don't fall into the "simple" category. The glazes you see on
our pots have been tailored to suit the clay and particular firing
schedules we use, plus some are double applications, etc. We do have a
good gloss white which works well in the cone 5-6 range and we'll put it
up on the site tomorrow (minus pictures, we used it for a special order of
20 slab built planters 5 years ago and didn't keep any of them or the
glaze,around!), plus anything else we find that we think might help you
out. Possibly some other folks have some simple glazes they could
contribute to your project as well?

Have fun with your high school ceramics classes!

Sally,
We will respectfully decline to give those particular formulas away just
yet. There are some "tricks" there which we wish to keep to ourselves for
awhile.I suppose it could be likened a bit to the Home Ec teacher asking
Colonel Sanders for the secret recipe of herbs and spices for her class.
Just not comfortable doing that at this point.We appreciate your work and
what you are trying to do but just can't part with those glazes yet as we
are using them to make our living. We trust you wouldn't "copy" us but we
already have potters in this part of the world that have tried their best
to duplicate what we are doing and we just want to sit on the glaze
formulas and techniques awhile longer.They represent all the work Cindy
and I have done since we got together 8 years ago. Maybe we should write a
book. Anyway we hope you will understand. Does any one else on the list
have some input on sharing "special" glazes? Are we being unreasonable?

Jim,

I have to agree with you. I don't mind sharing those recipes which are in
general circulation....we used Ron Roy OBM, Yellow Salt (slightly modified)
Conrad's moonlight (again slightly modified), and a bunch of others.
Will I give out our modification to Yellow sale? No. For sales we call it
the new blue. It was a simple mod that anyone playing with the glaze could
do in their first try.

I think too many want to just get a recipe, slap it on their pots and away
we go, claiming that you owe it to them to divulge your 8 years of work. We
all know that generally doesn't work because of all the variables involved.

I think I've found that you develop your own look and style when you do your
own work. If you're not willing to do the work, use stuff that is already
in the books. As John Nance said in Mud-pie Dilemma (I'm re-reading this
one right now) there is no simple way to becoming a potter. You can't short
cut it. You have to learn it all.

Your answer to Sally was very respectful and gentle.

Hi,
I haven`t met a glaze as simple as `Ebony`. It fits on my main 2 clays,
Plainsman M340 and M390, doesn`t craze, doesn`t run. I have fired it
successfully from ^4 to an almost ^7.

Barnard slip--50%
frit 3124----50%

It`s a very dark, shiny brown.

You may have a problem finding the Barnard. I was told by Plainsman that
it is no more, but later found it, or a very close sub dubbed the same
name at Green Barn in B.C. The package credited Laguna.

You can also check Alisa`s work and tests at

www.alisapots.dk/ Others on the list also have good tests and recipes

Possibly some other folks have some simple glazes they could

No, I don`t think you are being at all unreasonable...you handled the
awkwardness
nicely.

Lela, who one of these days will get up there to see your gallery. I`ll
hitch a ride with
my `always anxious to drive`
anywhere travel buddy has some work at the craft council gallery, apparently
close
to you. We are in Lethbridge.

Jim, there is nothing unreasonable about you declining to
give your glazes and years of work to anyone at all. There
are a zillion glazes available to anyone who wants them, both
in books and on the internet. There are commercial glazes
by the hundreds available from various clay & glaze companies.
So no one will go without, eh? Many people are happy to
give away their glazes, and many are happy not to do so.

Our glazes/surfaces become our own through our work
and experience, anyway. Students can experiment, teachers
can experiment. If they don't wish to do so, they can make
other choices.

Such decisions are personal, and always no-fault.

regards

Dannon Rhudy

Sounds like our teenage son!!"Always anxious to drive" . We'd love to have
you visit Lela. We've got those four pots of Charlie Hilton's sitting in
our front window right now. Real pieces of Alberta history. Always happy
to have Clayarters visit. Craft council gallery is just a few blocks away.
