I forgot to mention this in my recipe post:
I never had an official firing range for Candy DePew's slips (she did a
seminar at my University, and somehow the cones/temps disappeared from all
the notes, including the school's that I could ever find). I have just been
experimenting with them via trial and error. I fire them in my bisques,
obviously, to 04, and when I first used them I was layering them over and
under low-fire (cones 05 & 06) glazes, and they did fine, and in fact, for
anyone firing in this range, they create an almost "high fire" look that is
hard to come by in that range. I have since fired the blue up to cone 6/7,
and it stayed fine, though it does make for a different look, and does seem
to contribute some to the glazes over them running.

I'm looking for some slip recipes for reds and/or yellows--either recipes or
resources for locating same would be much appreciated. Having never mixed
slips, let alone glazes, "Clay and Glazes for the Potter" (3rd) is my
current source. There is no Vanadium Stain available and that is the only
possible listed for yellow.

Hi Kathy,
I use dried trimmings to make my slips, and I use porcelain clay, so if you're using an iron bearing body like a red earthenware, obviously your results will be vastly different as to colorant additions for a red and yellow slip. For red and yellow I use inclusion pigments from Ferro, as I fire to 1300 C and need the colors to survive high temperature; 279 497 Bordeaux Red, 279 496 Intensive Red, and 239 416 Yellow. You can use percentage additions up to 12% depending on the intensity of color you want. I use the formula 3 parts clay to 2 parts water.
Its helpful if the trimmings are small in size, half golf ball size or less, and completely dry so the clay will slake properly when it is put in water. Add the colorant to the dried clay, and add clay and colorant mixture to water so the mixture gets surrounded by water as it falls in. Be sure to wear a good respirator and do the operation in a well ventilated area. This formula is barely enough water to complete the job of getting all the mixture wet, so you have to sprinkle it in an array as you put it into the water. Now let it sit for two or three hours and mix well with a drill mixer. You will see that you have a mixture which is thicker than you will probably want to use, but adding more water will increase the shrinkage, meaning more cracking on your pots as it dries. Add a teaspoon of sodium silicate for a quantity of 5000 grams clay body to 2000 ml water and mix in well. You will see the mixture turn to a very thick liquid, just right for combing, chattering, brushed through (etc.) slip decoration techniques. Add more sodium silicate if you want a thinner slip, not more water, as water is the cause of cracking problems as the slip dries. I wait until I have trimmed my pi
eces to apply colored slips,(leather hard), and since I live in a very dry climate, (Colorado), I use a damp box to slow the drying. It's possible to use colored slips quite thick in this way and not have cracking problems.
Best of luck,

I want to compile a photo essay on slip decoration to add to the
clay/glaze section of my web site.
I was very interested in David Beumee's contribution on 28 Feb.
If there any other list members who use slip decoration I would like
to hear from them. I am particularly interested in how they actually
make their slip, colours, and how the slip is applied to the clay.
I am aware of the fact that all that needs to be done is add clay to
water but there are extra little considerations that affect the ease
of use and its firing.
If anyone considers that it might be of interest to the clayart list
as a whole please post here.
Alternatively, please reply off list, where I can explain in more
detail what my plans are.
click on http://www.gartside.info/clayglazeintro.htm
It will give you an idea of the type of article I create.
I would of course acknowledge your contribution.

Brian, I like the webpage with the tests.
I work with slip decoration in 3 different ways
currently: Hakame brushing (under glaze and also on the body of
unglazed work) and also zogan inlay on glazed ware and also on unglazed
ware that is fired in the wood kiln. At my teacher's workshop, all
the ingredients for the slip were mixed up with water separately and
screened, and then mixed by the wet measure/ladle. In my studio, I do
both wet measure and dry mixing. One of the advantages of wet
mixing is that it helps you keep dust out of the air.
I am currently testing Slip Gahon, a white slip that is
applied to bisque ware and is used under a clear glaze. It does a
spotty pink blush under the glaze.
My recipes all use Japanese materials, so I don't know if it
would be helpful to list them.
