" I am
trying to find a way to make plates have more depth to the glaze. I have an
1997 CM article that indicates that the use of a white slip does this (from
Robbin Hopper's Ceramic Spectrum page 161). It says to apply to wet or leather
hard clay. Do I still bisque with only the white slip, or are they talking
about applying the white slip, waiting until it dries and then glazing and
firing only once? Does anyone use this technique? This is for ^10 reduction
Most likely you'll want to bisque the white slip on to ^06 before applying
the glaze and firing up to high fire reduction.
It kinda depends upon what kind of glazes you have. Most glazes are
formulated to work (generally speaking) on work that has already been
bisqued. It is also easier to glaze a piece that has already been bisqued.
However, there are "once-fire" glazes that you apply to greenware, but I
don't think most of the glazes that Robin Hopper talks about in "Ceramic
Spectrum" are once fire.

After reading your message, I rolled out a 12" circle of rough
golden-red clay called Tecate Gold. I placed plastic from a grocery bag =
12" plastic plate from WalMart to use as a form and placed the clay disk =
it. Drizzled white slip on it and rocked it til it covered evenly, then
poured off the excess. It's now drying. Next I'll apply a clear glaze in =
same manner. When that's firmed up a bit, I'll do some carving to reveal =
clay beneath. Then it goes into a glost fire bypassing the bisque one. =
shall see what happens. I always fire my electric kiln slowly. Three =
on low, three on medium, then on high til she hits ^10.
Next Wednesday, I go to friends in Greeneville, TN for a weeks =
hope to hit a major show in Abington, VA. Also there are several potters =
the area so we all may get to meet lots of artists.

I have to ask a silly question. Yes, I could fire twice to try to =

this jinx the magic?
