I am a relatively inexperienced potter and would like to learn more about
oxide washes. I have seen pictures of ceramics which were decorated/colored
with oxide washes. Unfortunately there were no details accompanying the
photographs. Any recommended reading, information, or techniques would be
greatly appreciated.
Thanks in Advance
Ed

Greg,
You can just mix with water or you can also add some frit or low melting
feldspars.
You mix up as much or as little water as you want. Generally keep it
thin like a watercolor wash. I've used several of these on bare clay
from ^04 to ^14.
>From Val Cushing I think:
Rust Orange Tan
34 red iron oxide
33 rutile
33 gerstly borate
Medium Green Wash
25 cobalt carbonate
53 rutile
2 chrome oxide
20 gerstly borate
Grey Blue
60 cobalt carbonate
20 manganese dioxide
20 gerstly borate
Orange Tan
67 rutile
33 gerstly borate
Orange Tan Straw
50 rutile
17 titanium dioxide
33 gerstly borate

HI Priscilla,
I frequently use oxide "washes" on my textured pieces.
Really simple,just add a few teaspoons of oxide to a cup or two of =
water.
Paint on and then sponge off and it will stay darker in the textures.=20
There will be some staining of the clay, but there is a definate =
definition of the texture.
I use iron oxide, copper carbonate and cobalt carbonate for this =
method.
You don't need more than one of teaspoon to a one cup water of the very =
expensive cobalt.
It is a very strong colorant.
With the iron or copper about 3 tsps to a cup....as with anything, you =
will need to
test to get the results you desire.
I have found that at c6, the iron is the only one I like without a =
glaze.=20
The blue is pretty nasty unglazed.=20
The copper can work unglazed but for the soft green (almost celadon) =
color I want, I use
a semi-matt clear glaze. If you are interested, I would be happy to =
share that glaze.
I think I got it off Clayart anyway!=20
The copper is the most unpredictable wash
..It burns away if too thin & can be a metalic grey to black when very =
thick.
Have fun.=20
Oh, almost forgot...I usually use these on bisqueware, but they work on =
greenware.

Clayart having flown into cyberspace and crashed, this of course is the
time my mind is full of questions, as each pot's glaze is dunked,
cleaned up and placed in the kiln to await firing, once the wind stops
hurling sand down our dirt road. I've played unsuccessfully with oxide
washes prior to this firing ... now I want to see results! Handsome
results! I've sprayed&splashed my favorite pot ever (22" bottle/jar,
coiled/thrown and carved, composed of 3 different scrap clays) with
rutile wash and thick soda ash ... and thin splashes of illmenite...
after reading and re-reading Clayart files on oxides. Any
recommendations before firing occurs??? Firing high is the plan,
probably to ^11. Thank you.

In the Mojave still on the lookout for my "voice" ... think I'm gonna be
too old to do more than squeak by the time I find it ... or that the
tongue in my cheek will choke it into infirmity.....

Alisa, Valice and others asked about the results from using oxide washes
on my favorite pot so far. And ONE of my new, best friends laughed at me
for experimenting with my best, all of 22" pot where I'd finally
achieved just enough folds, gouges etc to suit me.
There was a small misunderstanding by some. I wasn't mixing the rutile,
ilmenite and soda ash into one wash... might another time but not this
firing. First came the rutile wash which was sprayed on the whole pot;
then I added dribbles and streaks of soda ash and ilmenite. The rutile
gave a light tan cast to the whole pot ... I did not particularly like
this look ... I was hoping for the creamy look that sometimes comes with
a rutile wash in a salt fire. The soda ash was a surprise; I expected it
to be black but it created a glaze-like glossy but putrid greenish look,
almost metallic, with some colors, blues mostly ... maybe from the
rutile?... showing through here and there. Does that sound right???? To
be fair, I thought it was putrid, but my mentee, Dori, who adores every
little unexpected dot of iron or flying copper red which shows up where
it shouldn't be, liked this p. look. The ilmenite appeared as I
expected..... kind of cindery streaks and dots... although I thought it
might melt more since the firing went to ^11. All in all, think it
should have been shinoed with ilmenite on the shoulder.
Joyce
In the Mojave thrilled with the direction Clayart is taking with
Cookbooks, Committees, and Other Grand Things ... but
wondering what the heck is going on with David and Vince ... discussion,
discension and debate with informed intelligence and humor rampant makes
for exciting cybering ... but you guys are getting a bit vicious. Why
isn't Dannon breaking it up??? Afraid of getting clobbered? No, not
Dannon ....
