Hi - I've looked in the archives and can't find a mention of yellow ochre.
My Illustrated Dictionary of Practical Pottery (Fournier) states it's a form
of iron. Does anyone use it to make a cream-coloured glaze? I've been
doing trials with rutile added to a basic white glaze (Plainsman's 77C04),
and while the trials aren't finished yet, I think when I do finally get it
dark enough, it will be more of a tan than cream. I'm looking for a really
rich cream ^6 semi-gloss or gloss that is almost yellow (would that be
butter-cream? ). Any help that will shorten up this testing process will
be appreciated! Thanks...

I started out with nothing, and I still have most of it left.

Not to directly answer your question but I was in Montana this summer
digging slip glazes when I ran across a Montana potter in Whitefish who
actually digs a "yellow ochre" which he showed us. He uses it as a
colorant. I was ablt to locate some yellow clay balls in a bank at Tally
Lake which when fired come out more clear than yellow. We also have clays
from Somers and Big Fork which have a yellow to gold color when fired to
cone 10. I'm currently using these clays to contrast the brown to yellow
firing clay we use as a slip glaze. Rutile added to these give a beautiful
yellow to green color. Let me know if you are interested in these naturally
available clays and more info on what we've been doing with them. I'm test
firing some of these clays this weekend with Mason stains of ambrosia and
vanadium yellow to see what comes out. At 11:46 PM 11/13/99 -0500, you wrote:

I have used yellow ochre in place of rutile as a colouring agent in a
previously white glaze, making it ivory, or cream. As rutile has
titanium in it, the titanium changes the glaze texture and surface more
than the yellow ochre. A small amount (.5%) modified the glaze colour
sufficient for my needs.
I did get a yellow on a light clay body with the following recipe (from
Clayart):
Peachy Keen Cone 6 oxidation
Custer Spar 45
Gerstley Borate 13
Whiting 8
Dolomite 6
EPK 3
Silica 19
Bentonite 1
Rutile 8
Zircopax 6 (I rounded out the decimals)

My experience with yellow ochre is that it may warm up a white but not
necessarily produce a cream color. The glaze base really has a lot to do
with it. I use a light rutile(10%)in a glaze to make a creamy colored glaze
with no trouble so perhaps it is the base that needs to be looked at.

Thanks for the offer, Rudy, but I think I'd better stick with trying either
rutile or ochre/iron oxide for this quest. I have enough trouble getting
glazes to work without introducing "unknown" ingredients. But I really
appreciate the offer. I'll bet some of the glaze gurus (you know, those
guys who know what they're doing in the glaze department) might be
interested in trying some yellow native clay---sounds interesting.

While you're doing your research, try looking for French potters around
Rousillon - just east of Avignon.
Rousillon is a small town perched on a hill of ochres, from reds to
yellows - much involved in the fabrication of good quality oil paints and
water colours.
I know local potters use it in their glazes - I bought some pots - but no
idea of techniques, and I no longer have their addresses.
