Hello,
I am new to this forum and have only a limited experience with glaze
making. That's why I have started with simple recepies and pictured
books such as "The Potter's palette" by S. Ogden and C. Constant :-)
I hope to improve and possibly fire at lower temperatures, like cone 6.
I would be very interested to know what you think about this book and
its glaze recepies. I would appreciate your comments and advice because
I have problems with running glazes.
I have done some tile testing, adjusting temperature and line blending
the base glaze with several materials. Pictures are sometimes better
than words for explaining things, so please have a look at my small
draft website :
www.perso.be/ceramic
Alex
P.S. I have a round electric kiln (120 L, 60cm diametre, 46cm height;
maximum 1300'c or cone 10 Orton with automatic regulation).
I use buff and off-white stoneware clays + simples ingredients (no
frits, barium, strontium, lithium carbonates at this point, perhaps
when I become more "expert"...)
The firing takes about 8-9 hours till 1280'c with a 60 Min. soak
(=cone 8 Seger "touch down").
++++++++++++++++++++
Base glaze used is from "The Potter's palette" book
by S. Ogden and C. Constant :
( Recipe C)
Potash Feldspar.....50
Kaolin*.....20
Dolomite.....20
Bone Ash.....10
Cone 10 Seger 1300'c according to the book
* In my book (in French) it is mentioned "Tesson de porcelaine"
(that is actually the extra fine chamotte made of fired
Porcelaine/China!).

Hello Alex, I
do not know much about this book but a recipe or too.
The way Tony Hansen says , in my words,be carful from text book.
Especially the old ones these books are full with un safe materials.
I suggest you to buy too most modern as well as educative ( I made up
this word but my translator say there is such a word) Back to educative
books:
Cone six glazes of Michael Bailey to know all you can do in ^6 oxidation
and Mastering cone 6 glaze of Ron Roy and John Hesselberth will teach
you how to make your glazes safe as well as beautiful.

Hello Ababi,
Thank you for your replies. I will keep your Deep yellow recipe for
my future firings at lower temperatures once I get the book by
Michael Bailey you mentionned.
From what I know, the Frits you indicate are not (easily) available in
Europe, and I would rather prefer to use local materials available to
me,
especially the simple raw materials such as feldspars, whiting, flint,
kaolin, dolomite, colemanite, zinc etc. Those "natural" material should
-I am told- provide many (high) stoneware glaze components
(K2O, Na2O; CaO, ZnO, MgO; B2O3 and of course Al2O3 and SiO2 etc.).
I don't use glaze softwares (yet), I somehow tend to prefer the "line
blending" approach of G. Daly, but I might change my mind if I don't
manage
to secure a stable glaze :-)
I would like to find some stoneware glaze recipies that do not run on
vertical surfaces. Temperature range around 1260-1280 'c OX (cone 7-8
Seger).
Base glazes: transparent, or opaque -preferably satin- with good colour
response (yellows, roses and blue especially)
Anyone has managed to get an interesting orange (or red) without stains
in
electric kiln?
I know that those are difficult ones!
Too many questions...
Thanks

Sorry Alex
You really don't need frits for this temperature.
I do not fire to this temperature so I will give you some links instead
of recipes. Yet if you send me the problematic glaze and cone, I
might be able to adjust it using Matrix.
http://www.potterymaking.org/recipes.html
http://cclay.com/glazes.htm
Can you buy G.R.T. a German low fire casting slip , red clay?
It can be used to reformulate Alberta slip or Albany slip.
In Chris Stanley's wonderful site:

From Japan

Good glazing
