Alisa, thank so much for your ongoing testing and sharing. It is an
incredible service to those of us who are not pros, and must rely on you
pros to guide us in the glaze business.
I am encouraged by these recipes to depart from my regimen of terra cotta
and majolica, and I and two potter friends will spend the winter working on
moving into mid-range clay and glazes. We'll start with some on your list,
which should be easy mixers. Again, much gratitude.
Marian in Michigan (I'd say I was cold, but know that I won't get any
sympathy from someone in Denmark)

Hi Alisa,
You are fantastic! All those tests! Thank you so much for sharing
the results. Now, I won't even know where to restart my glaze mixing!
You are so kind to provide all of us with detailed accounts of the
glazes, your results, and your reactions.
All the best.

Dear Clayart,
These tests are done in the last kiln before Holiday travels.
The highlights were Soft blue, Blue Gree and Val's turquoise.
(That seems to be in keeping with the Blues theme at present).
Otherwise the ball crawls and fake shinos were intersting to try.
I am busy reading Ian Currie's book "Discovering Glazes", a very
good text. Have to make big test tiles as well as bowls.
Hope there is something you can use.
I am soon turning off Clayart Mail unitl mid January,
as I am going WEST young man! If you have any questions
or replies, I will be at the computer up unitl the 24th (about 6
hours before the Amercan cousins head for a(nother) cup of cheer.
I really wish you all a good happy ending to the year and hope
you all get a good start on the New Year!
Best regards,

The recent batch of tests were very mixed. I wrote up the ones that made=20
glazes that looked mature.
I have trying for a long time to make a 5 x 20 base from Tony Hansen's 20 x=
=20
5, that is more of a semi matt.
Since I seem to like the effects of Dolomite and Wollastonite, I kept them=

it react. Not too stable, not too much
bleeding, sort soft.
I think I have it, but since I cannot analyze it, maybe someone who has the=
=20
software would download it
for me?
Otherwise, the darling of these tests is John H.'s Floating Green. It took=
=20
me this long to try it because I kept forgetting
to buy Whiting. I am tantalized by the color play in this glaze and the=20
surface. That was a tasty morsel John and Ron, before I
get the book!
I have made an error in my notes. I wrote down the Leather recipe under=20
two names, Leather and Buttery Cream. So, if it is
Buttery Cream, please let me know.

Dear Clayart,
Back to the testing slab. Weather has been so great, I have been =
throwing outdoors more than mixing indoors.
Now I have virtually everything outdoors, so got the mixing done also.
Understand, we live for these short summer months, if we get a summer =
and not just a "green winter".
The darlings of these tests were Cream of Mushroom, Icing Pink and =
Butter Satin Matte. All nicely melted
and attractive. Paul's Icing Pink is crazy. Make all the little girls =
swoon over the bucket, waiting in line to
glaze their "hand thrown" pots. Reminds me so much of the Duncan Dugan =
man. The guy who used to deliver=20
bread to our house in his truck. Every week one of us kids could chose =
a cake. We were 5 kids, so I had to
wait 5 weeks to get a box of 6 Pink Icing cupcakes. Paul, this glaze is =
so cute. Good stuff of piggy banks.
Actually has a very nice and smooth feel. Much more lively than a pink =
stained glaze.
I had many cups of all the variations of this glaze with cobalt, Rutile, =
Zircon, tiny amount of Nikkel, and RIO.
Since Cobalt is so expensive I try to limit my blue glazes (maybe for =
other reasons, no mother in law, alas) =20
But I like a mottled, variegated blue.
By throwing all the test cups together, I have a very mottled and =
variegated blue gloss, very similar to
the Bright Sky Blue. This would make sense because all of the tests =
contained 1% cobalt and thereafter in
descending precents, Zircon, Rutile, RIO,Copper carb. and Nickel. The =
predominating additives Cobalt and Rutile with a=20
small amont of opacifier, give a very streaking but not runny blue. =
Attractive. Glad I have a bucket of useable glaze from all those test =
cups.
When testing a base with colorants, it could save time and costs to =
throw them all together for a useable glaze, instead of wasting all =
those 100 gram batches. =20

Dear Clayart,
Now that I moved my studio and shop out Krusm=F8lle farm, my former =
studio is a glaze lab. =20
It is very easy for me to set up and make tests, because all of the =
materials are very accessible.
Organization in the test lab is key. I keep everything nearby the glaze =
table so I do=20
not have to jump loops to reach for things and forget what I am doing in =
the process. I was
lucky and got to purchase glass containers with an easy off lids with =
rubber seals, that hold 2 pounds for cheap.
All lined up with name tags on my table. Boom, testing done. Cuts down =
the dust also because
I am not opening and closing bags or plastic lids that stick.
The tests were overall good.
The crystal tests were amazing, and I am sure the firing ramps down are =
very important in achieving these results.
Since I have never tried these before, I am still enchanted and charmed =
by the structures of the large crystals.
The redux. glazes in oxidation were all quite good. Similar to the list =
Marcia had supplied, I found many good glazes
when fired in oxidation. The Turquoise and Phila Green were the =
darlings.
In addition, Marianne Lombardo sent me the Touchtone Red recipe she had =
received from Clayart. =20
Because she wanted to see what it would do in the blue families, I =
tested it with some other colorants.
The Cob. carb. + Rutile gave a nice cobalt green with blue, blue =
crystals.
Hope there is something you can use,
regards from Alisa

Marianne Lombardo on sun 8 sep 02
Dear Alisa;
Thank-you so much for posting the results of your glaze testing. I know so
many of us look forward to them. I really like the format that you use and
the way you report the results of the tests. I also like it when you
indicate which tests you liked the best. Those are usually the ones I try
first, because I think our tastes are quite similiar with glazes.
A question, if you don't mind. By Borax frit, can you tell us exactly which
frit you used? Thanks!
And thanks also for the suggestion of using smaller containers to hold
ingredients for testing and having them all line up on a table, ready to
use. Now I realize why it takes me so very long to prepare my glaze tests.
I keep opening and closing large buckets of some ingredients, a real pain.
I have a lot of small canning glass jars so I plan to put my testing
ingredients out in a more organized fashion, as well. I will also keep a
look out for some inexpensive, easy to open containers. Good tip.

Dear Clayart,
These tests are from a group of recipes harvested from of Clayart and =
some other sources as noted.
The Berry Rust is Carol Tripp's revision of Craig Martell's revision. It =
is a good alternative to glazes like Randy's Red that have a high =
percent of G.B. The glaze is a classic red iron gloss. Nice one.
The darlings of these tests are the White Glaze because it is smooth and =
waxy. I like that.
Burke's Deep Turquoise, now fondly called Burke's Turk, has a rich and =
lush color. =20
Nutmeg is a good example of an iron-ochre glaze with many nuances, =
character and nice feel.
You do not need to imagine what I am talking about. See the tests at =
www.alisa-potshop.dk. Cool.
There are also three tests with Peter Pinnell's Bronze Green with three =
different white over,including the same combo
that was in CM March 2003. 3 different and 3 nice results.
We are having summer thunder storms. I rode my bike as fast as I could =
from the studio while really big lightening bolts flashed down to the =
fields. It was exhilerating to beat the rain and feel the danger of the =
electricity!
Such a dare devil. I admit I am confused. Tony wrote that about do not =
tell the other 4 guys? Am I a prude and I do not know it? What other 4 =
guys?
Never mind, I am going to see what Little Claus, Big Claus, Clausman and =
Claus are doing in the kitchen.
Hope these tests are of some interest.

Dear Clayart,
These tests were fired in my smaller kiln, with exactly the same ramp =
and cool down ramp I use in bigger kiln.
I fired test tiles of my usual glazes, so I had something to compare. =
The glazes from this kiln look identical to
those fired in my bigger kiln. I use a kiln controller for both kilns =
with exacting degrees, up and down.
These tests were done to determine coloring possibilities in a base.
I had been testing dolomite bases, and used Grace's "B" Base, published
in Clay Times, Sep-Oct. 2002. It is a variation of Tony's 20 x 5, which =
is a base
I tinker around with, keeping the materials all 5 x 20. This seemed =
like a good=20
candidate base and it was. The surface is quite waxy and Vellum like, =
as Charles Moore
has described this type of surface of to me. =20
The other tests are overlapping tests, where I kept the constant first =
glaze as
MC6G Licorice. There are some tests that have a fur, similar to =
Floating Blue.
The next tests were the idea given by Ron Roy that Chrome fumes. =20
Take it to the bank Roy. It certainly did.
I have used a direct substitution of a new Frit I am trying, Frit J.
Unlike my other Frit 623 and 169, it has no Barium of Zinc.
I will send the analysis under a separate post.
As I am working away with GlazeMaster, I have not mastered the unity =
formulas yet.
The look-feel results were all good, but I have not cracked the surfaces =
of the tests yet on
GlazeMaster.
You can see most of these tests now at=20

Dear Alisa:
Thanks very much for your generosity in sharing your glaze test results
(and photos!) with us; it is very much appreciated.
I have been on the hunt for a teal glaze (have tested a few with no
luck) and Grace Lewis' "B" Base glaze with the 1 cobalt carb. and 2
chrome is one I will definitely test on my iron rich clay body.
Also, congratulations to the "baby" kiln in replicating the tests
exactly the same as the big one. You must be thrilled! I am very
happy for you.
Warm regards,

Dear Clayart,
I collected recipes from issues of Clay Times, as well as the =
interesting revisions Peter Pinnell has made from his popular Weathered =
Bronze Glaze.
One thing I realized, is that I had always used Ball Clay in his recipe, =
although it should be Kaolin. My glaze works well, with a good green =
patina look. However, many on the list have said that they get browns. =
I tested it with Kaolin, and it was brown. I have tested some of his =
revisions with both Kaolin and Ball Clay as gram for gram sub. I =
personally prefer the Ball Clay versions, although the Seafoam is =
brighter with the Kaolin. I also made a couple of tests with subbing =
Strontium by MW for Barium in Em. Cooper recipes. The Strontium did not =
give the color response that Barium does.
The Purple Opalescent glaze is one I tested here again, with both G.B. =
and my Frit J, gram for gram. I also tested the Blue version given with =
various amounts of both Cobalt carb. and Copper Carb. Previously I had =
made tests using Colemanite instead of G.B. I have never seen any other =
color produced by these tests than browns. Can't make it work for me.
Peter Pinnell's Green Black is the darling of these tests. The Grey =
Greens are also very attractive. John Hesselberth has written an update =
to Clay Times about all of the revisions of Weathered Bronze. He had =
them tested and they leach Copper and should not be used for food =
surfaces.

Hello again Alisa:
Since the Pinell Bronze green works great for me,I went back and looked at

again thanks.

Carissa Doying Salazar on fri 28 may 04
Hi Alisa,
When I sub strontium for barium I take the amount of barium and
multiply it times .75 or the amount of barium divided by 4 times 3.
This might give you better color results.

Alisa,
I can't tell you how much I appreciate your testing and sharing the =

results with Clayart. I am following in your footsteps, some of the =
glazes
I have tested before reading your results, some only after reading what =
you
have to share. I am not an enthusiastic glaze mixer. For me it seems =
like
a lot of work and so far I've not come up with the 2 or 3 that I like =
well
enough to make into big batches of glaze. So your work is a great =
stimulus
for me to get back to the mixing table.
Question, what water are you using. I'm sure that your "tap" water =
won't
compare to mine, maybe not even your rainwater! But maybe if you are =
using
distilled water. Our water is VERY hard (high calcium) and I suspect it
affects my glazes. I am going to follow Dale Neese's advice and try
rainwater next.
Again thank you so much for sharing your research! =20

Alisa,
The most difficult part of glaze testing for me is the tedium of weighing.
How do you manage all these tests? Do you weigh everything by hand or do you
have a more efficient means of tackling that problem?

Wet measure takes the tedium out of weighing. ;-)
In my last firing, because I noticed that deposited ash bleaches the red
out of my new shino type glazes, I thought I'd add ash to see what
happens. I happened to have rinsed wood and and amakusa stone mixture
50/50 in a bucket, in a slurry form. You scoop the water off the top and
then ladle out thick slip or slurry.
I did one test one ladle Shino type, one ladle Ash/Amakusa. The other
test was 2 Shino type/1 part ash/amaksusa. They really paled the glaze
out, the 2 to 1 being more bronzy. So, in Euan's last firing, I tried 1
part Shino type/.5 parts Ash/amakusa. This looked better, but it was
hard to tell exactly what it would be like in my kiln, because Euan
introduces a soda ash/sawdust mixture. Will test again in my kiln. Will
also test adding wood ash and no amakusa.

Alisa Liskin Clausen on tue 9 may 06
Dear Clayart,
I am working more and more on coloring bases I use, as well as recipes
using a local red clay. However, every once in a while I take all the
recipes I
collect from Clayart or publications, and make some tests to see how the
glazes do with my materials in my kiln. Also gives me something to talk
about with
some other tester friends.
The photos of the recently posted glaze tests can be seen at
http://pg.photos.yahoo.com/ph/alisapots/my_photos
When I first read the Jayne Shatz article in CM Sep 05, I did not test the
glazes. There is a good portion of both Gerstely Borate in Barium in them.
With all the options we have today, I prefer not to use either material,
only small amounts of Barium in glazes I cannot get the achieve the same
color
response without. Certainly there are better options for a clear liner
glaze than the one published with almost 9 percent Barium. However, when
the Ketchup
glaze was discussed on Clayart, I looked up the article again. I have now
tested the glaze recipes. I did not post my Ketchup tests, because they were
all
brown. I will re fire them in the bisque. The Alligator green glaze is one
portion glaze mix and almost one portion Zircopax. This type of crawl can
be achieved
cheaper with much less Zircopax or Magnesium.
The darlings of these tests were David Hewitts Eggshell. This is one of my
favorite types of glazes, a nice Dolomite mat. Also Lili's Noah's Port is a
fascinating
glaze both in color and movement. I personally like using red clay in the
glazes I make, and Lili's a superb example of a lush Red Clay glaze.
Althought my example of Frogpond Green Mat is gloss, due to my frit sub.,
the test is also a lovely example of movement and colors.
Best regards from Alisa in Denmark

others on the list follow suit, your food budget
should be zero for the next NCECA!
I was going to make you a cup with one of your tested
glazes, but that's a coals to Newcastle kinda thing!
Blessings on your house,

Hi Clayart!
These are just a few tests I have collected while reading Clayart.
Ron Roy's revision of Nutmeg is a brownish glaze, but lighter than the
original.
Edwards Slip Glaze has a very nice smooth, silk mat surface.
I re tested WoDo, which I use a lot of, because Lili was talking on the
subject of Dolomite glazes.
The others were mentioned on Clayart.
Photos can be seen at my Yahoo Photo site at
http://new.photos.yahoo.com/alisapots/album/576460762329430796#page1
along with my new improved indoor-outdoor glaze lab. A free table and
wonderful things can happen.
They changed the format and now I cannot figure out how to rearrange the
photos.
I am going to put the recipes through Glaze Master but that is not tonight.
I have been in
three countries today. When I was a kid, I would try to stand with one leg
in NJ and one leg in NYC. I do not even know if you can still
walk over the G.W. Bridge. Now I am going for the fourth, Slumberland.
Forgive me if I made any typos.
Good night,
Best regards,
Alisa in Denmark

Dear Clayart,
These tests are taken both from Clayart discussions, as well as many from
previous Ceramic Monthly's, that were neatly published in the 07 Ceramic
Buyers Guide, A Studio Reference, given to NCECA attendees. Besides the man=
y
recipes published, there are many other very good articles, well laid out
information and interesting ideas in the magazine.
The glaze tests are varied. Some are my favorite types of glazes, Dolomite
whites, and others are just grizzly combinations of Barium and Lithium, but
with interesting results. I fired two of Lana's 06 glazes to satisfy my
curiousity about glaze materials. One with no stifferners at all, and the
other that hardly seemed like a ^06 glaze. The fired results are the
visuals I personally need to further my learning.
the Green Dragon Mat will be used on some exhibition work. A lot of non
food, colorful and lovely mat surfaces.
In all, I am stunned and amazed by V's Tenmoku's crystals, lovely, although
high Lithium. Will have to watch for shivering.
Otherwise the Barium Blues were impressive at Cone 6 Ox. and I like my own
Revision of WoDo. Lili's Dolomite Mats are all lookers and the Green Drago=
n
Mat will be used on some exhibition work. A lot of non food, colorful and
lovely mat surfaces.
You can see the tests at my Yahoo album site at
www.alisapots.dk
to to Glaze tests, and click on additional glaze test
Album is called
Glaze Tests May 2007
Hope there is something of interest there for cone 6ers and possibly others=
.
PS
I got Unity now, using Glaze Master and it is all there for you and I to
learn from.
