Here's a recipe and explanation posted by Bob Wicks back in 1997:
"Here is a recipe that I have used for years and it works. First youl have
to understand that this body is very non-plastic and you can not model with
it for very long. Since the glaze is built into it when it is dry you will
note a dry powder forming on the surface as the liquid evaporates. This is
the glaze forming. If you place the project on a non absorbant surface like
glass no glaze will form there as evaporation can not happen at that point.
Nepheline Syenite 39%
Soda Ash 06%=3D20
Soda bicarbonate 06
EPK 06%=3D20
Ball Clay 06%=3D20
Flint 37%=3D20
2 tablespoons H2O per 100 grams
For colors=3D20
copper carbonate 2% turquoise
cobalt carb .25-1% for blue
Chromium .5-1% for green
Manganese dioxide 10-20% for gray violet
The Complete Compendum by Conrad suggests that you sift a mixture of 1/2
sodium and Borax over the finished product before firing. Sylvia Hyman, in
CM Apr. 1974, p 39 proposes that the first project should conmsist o 5
batches of 100 grams ea. totaling 500 grams. Mix well for few minutes.

sandwich bag, add 100 grams of mix pluys colorant and add 2 tablespoons of

I found this by doing a simple Google search with key words: "Egyptian past=

recipe". Many Clayart posts from the past will come up in Google searches.
Even better one can search the Clayart archives and find more information
than you'd may ever need to know.
How to make the cloisonn=3DE9 look.
I'd suggest an erosion process.
When the pot is dry, paint the "cloisonn=3DE9" lines with a water based
polyethylene (like Minwax Polycrylic). You could also used shellac or
solvent based varnish, but I like to use water based materials whenever
possible. After the coating has dried, scrub the dry clay with water &
sponge (or one of those scrubby pads). This will erode away the clay but
leave raised lines like the cloisonn=3DE9 lines. You could fill in the area=
s
with underglazes or different colored glazes. You could even go so far as
using a platinum luster on the lines after glaze firing.
