I am looking for a recipe for a Japanese type glaze called Kohiki. Actually,
rather than a glaze, I think it might be a slip applied to greenware, which
later gets a clear glaze over. When finished it is a white to grey to tan
color with random spotting and sometimes halo effects.
I figured someone out there in Clayart Land knows more about this process
than I and might be willing to share their vast knowledge... Thanks in
advance for your help!

Hi Chris,
You're right about the application of the glazes, sorry I can't help you out
on the recipe for the white slip. I've seen it a dozen times
various places but just turned the house upside down and couldn't find a
thing.
Anyway, what I can tell you is that most guys I know here who do kohiki
stuff add a LOT of iron to their clay. My teacher wedges in about 1 kg
benigara (red iron oxide) to 9 kg red stoneware. His wedging plaster looks
like a butcher's block when he's finished. The fired clay is nearly black
and the firing is fairly low temp., around 1200C - 1230C. The halo effect
comes from oxygen entering into the claybody from pinholes in the glaze.
All the applications I've seen of kohiki were to leather hard ware.
Hope this helps,
Mike

Chris,
I know it as slip gahon. To get the color variation, you
put the slip on bisque ware. You might try playing with Rhode's
crackle on bisque. Here is my recipe:
Gariome ball clay 20
Korean Kaolin 70
Kibushi refractory Ball clay 10
Feldspar 20
Use over Sangoyu (clear glaze.) The glaze you use might be as
important as the slip. Kibushi seems to have some iron in it.
Rhode's (crackle on bisque, from Jeff Ostreich) slip:
Borax 5
Zirc 5
Custer 20
Ball clay 15
Calc Kaolin 20
EPK 15
Flint 20
