Hi fellow Clayarters,
This is my first attempt to post on the list since the changeover.
I wonder if anyone could help me with a Cone 6 glaze or slip with a copper
penny look, shiny copper look? If anyone has such a recipe and is willing
to share it, I would appreciate it very much.
Thank you in advance.
All the best
Veena

Hi Veena,
This is one you might want to experiment with. It's definitely not
food-safe--lots of manganese dioxide and copper carb. Use due care when
preparing. Gives a bronze color. From Lana Wilson's book Ceramics: Shape
and Surface.
Kimura-Lawrence Bronze (cones 3-8, ox. or red.)
34 Manganese Dioxide
5 Copper carbonate
10 Alumina Hydrate
48 Red Art clay
3 Soda ash
Lana describes this glaze: "Stunning at cone 8 reduction (a note she added
at a workshop: "Runs if applied too thickly"). Another version of this
which is more expensive and more toxic, but gives a broken texture effect
is simply 9 parts by volume of manganese dioxide mixed with 1 part copper
carbonate."
Good luck,
Greg

No one seems to have posted this in reply to you, so here goes. I got this
from the list a while back. It works beautifully for me at cone 6
electric, and looks very impressive. It is a slightly runny, patchy glaze,
mostly a shiny copper with patches of dull brown. My friends find it
fascinating. Don't know abour food safety, but the only issue should be
the lithium, which is used in medication in far great amounts than will
ever leach from this. It may be what you want, since th other posts were
using lusters, etc. Let me know if it works for you.

thanks for putting up the pictures, nice, nice combinations. You said that the
glaze gibby's temoku flakes on standards mid-range bodies ( I use 153 and 181),
did you mean after glazing or after firing? also the glaze on your recipe page is
the origional? have you used the reformulated one and found it not as good?
Millie in MD. still a little disappointed that the clouds and wind caused the Blue
Angels air show to be stopped after 2 passes.

To get the shiny copper penny look, I use two glazes layered one on
another (dipped).
The first coat is the same cone 6 tenmoku glaze that Ian Macmillan
mentions, The top coat is another saturated iron oxide glaze,
that a distinguished local potter gave me - I call it Dale's Saturated
Iron Oxide.
Both glazes are cone 6, oxidation. And not completely predictable.
You can see the effect (as well as the glaze recipes) at
http://members.bellatlantic.net/~spilacho/
This is just a start at a site to show my pottery and related stuff -
apologies for the crudeness.
Check it out in case it is what you are looking for.
I am not expert, but I believe that the shiny penny (polished bronze?)
is caused by the iron coming to the surface of the glaze during
firing.
Note that Ron Roy provided to Clayart a reformulated version of
Gibby's Wild Rose Tenmoku. I use the original which Ian Macmillan
included in his post.
Also, I have found that the original recipe flakes (a lot) when used
alone
on various mid-range Standard Ceramic clay bodies.

Are you going to share the other glaze with us?

The flaking is after firing - the glaze doesn't stay on the fnished pot.
I think I tested on the same bodies (not sure right now - embarassing,
I admit).
I use the Gibby's recipe that I provided on the glaze page - NOT Ron
Roy's
reformulated version. The freezer-boiling water test succeeded on some
test pieces, but that is all the testing I have done.
I did test with the reformulated version, but did not like the results.

Hi:
I've looked at Gibby's before. I think the problem is from a lot of
lithium, which makes for some "free" lithium that migrates into the
clay/glaze interface and causes a very low expansion situation to occur and
you get shivering. Look at the glaze "flakes" and see if there is some
clay attached to the underside. If you see this, it is a sure sign of
shivering. The glaze is under too much compression at the interface and
you'll need to lower the lithium carb.
Gibby's has a high calculated expansion which makes all this sort of a
mystery unless you take into account the "high coefficient of diffusion"
associated with lithium ions. What I mean is, this stuff is really mobile
and the Li ions have a very small size and they really get around if they
are free.
I hope Tom Buck or Michael Banks will address some or all of this. Then
you'll get a real answer as in the killer post Tom submitted on Bristol
glazes. Now THAT was an answer. Know what I mean? I bet you do!
later, Craig Martell in Oregon

Stephen - your pots are gorgeous! I take back everything I ever said about
oxidation glazes - I'm not sure I could tell them from reduction pots....
thanks for sharing...

forward it to me off-list? Thanks so much!
