paul,
i would greatly appreciate any good cone 6 glazes that you may have
i fire oxidation to cone 6 now w. an occasional cone 5 for
floating blue. tonight i am drinking from an oxidized mug that
i recently purchased. it is one of the few ox pieces that i have seen
and like even though i fire to 6. i guess it is the rougher texture
that i like on some high fire pieces.
i believe that for many of us, we love our work enough to want it to be
different from a piece of simple "ceramics that aunt edna made from her
2 week course " you know what else ? it is a labor of love, no matter
how much other's boast. you cannot be paid enough at todays going rates
to
reimburse you for a great pitcher. but, "it's alright"...... to quote
the indigo
girls.
i believe more cone 6 glazes are showing up though, and appreciate tham
more than your average bear.
if you would not mind sharing some i would thank you.
gnite, cp

Dear Josh,
I agree that this is a difficult glaze for ^6 oxidation.
The best I've come up with is 'chun' look alikes using titanium dioxide.
Here's three recipes for you.
1 2 3
Soda feldspar 45.0 45.0 80.0
China clay 5.0 5.0
bentonite 2.0 2.0
Lithium carb 2.0 2.0 3.0 (hazard label applies)
Dolomite 5.0
Whiting 17.0 17.0
Zinc ox. 5.0 5.0 3.0
Quartz 24.0 24.0 9.0 (hazard label applies)
Titanium dioxide 5.0 5.0 5.0
Cobalt carb. 0.1
Copper carb. 0.6
No 1 gives a light green 'chun' using a small amount of copper
No 2 gives a light blue 'chun' using a small amount of cobalt oxide
No 3 is perhaps the most satisfying in that it does pick up the colour
from iron in the clay and is best used over an iron bearing clay. Like
all chun glazes this is low in alumina but in practice it doesn't settle
out too badly although it is a bit powdery once on the pot.
Ron Roy et al may well criticise the use of the Lithium and, if you are
concerned about it, you could either leave it out altogether- or leave
it out and increase the Zinc ox by that amount.
I'd be interested to know how they come out.

Hi peeps!
I'm experimenting with cone 6 oxidation galzes this semester. If
you have any good glazes to recommend I'll mix 'em and try them at school
and report back.
Additionally, I'm woking with a cone 10 clay body for gas reduction
firings, so if you have any interesting cone 10 reduscion glazes send
them my way.
thanks! peace Em (at U.Hart)

Hi, there, Em.
I am also currently experimenting with cone 6 oxidation glazes. I've
recently created a website showing the results of my test along with
the recipes. To see them, go to:

Hiya;
I got this recipe from the archive. I don't know if it's good or not-still
working on it. I got a shiny to satiny white when thick and burnt orange

below. I have not worked out why it turned orange. Would like to see what
other comes up with.
Glaze name: Bird Matt
Cone: 6
Color: silver white

comments: Ellen, about l978 Ruth Duckworth used a glaze in Banff that was
called
it with 5% Rutile or Ilemanite. I loved the glaze. Satiny silver-white, not
blue though.

cone 6 is just a number.
a temp.
it is not a concept.
what is cone 06?
a temp.
it is not what temp you fire.
it is what you do with the clay at that temp.
i would think we are getting over the `good old boy` concept
of `hell, i got big balls and fire a wood kiln. all other potters
that do not fire like me are pissants`.
total b.s.
why not cone 10 oxidize?
why not cone 3 oxidize in a gas kiln?
so much depends on your own idea of
aesthetics of clay materials.
i love runny melted, stick to the shelf glazes with
dark brown clay. cone 11.
it is what i like. no one else on the planet has to accept
that or even care what i do. but, i care what i do.
i have said this many times:
if mr. hamada had been put in a prison, had only a small electric
kiln that fired to cone 06, had some chemicals and clay....no wheel, just
his hands.
i bet he would have made some damn fine pots.
and i totally agree with lilly. there are so damn many recipes, ideas
and concepts about `shino` it makes our head spin.
it all depends on what you are talking about.
old seto shino from japan.
american shino of jenny wirt.
malcolm davis shino.
or the three hundred variations of those recipes and ideas.
and then the 7,000 derivatives of those ideas.
and it still comes down to about three glazes. couple of temps and
some flux material.
make something of value with the kiln you have.
try and please yourself...not some judge in a show you
are hoping to get in.

electric, gas, wood, paper, coal, oil, dead grass and twigs.
just fuel. potters make pots with all the above. some don't
even have a kiln.
just a hole in the ground.

no matter what the discussion, no matter
right or wrong. deep thoughts and research.
the work of those doing cone 6 research has
been stunning.
think of what electric firing potters had
10 years ago. think of the negative feeling
potters had about firing `only` with electric kilns.
that is changing fast. as it should.
if you fire an electric kiln, stand up and be counted
as a potter.
there is no better or worse, no snob can
push you around.
the work depends on the quality of the potter,
not the kiln that is used. or temp you fire.
thanks to all that have helped make this possible.
it is an ongoing struggle.
