Hello Claybuds,
I thought I would add to the discussion on shinos. In my experience, the
rule of "shino first or be cursed", is one that I follow. I remember
trying iron slips, temmie, and celadons under Malcolm's shino (high soda
ash), and having the surface of my pots come out with huge blisters and
rough surfaces. I have also used Penn State shino, (low soda ash), in
combination with M.D.'s shino over and under with no bubbling at all. . . I
did a series of tests years ago using different shinos together, over and
under and never had a problem. There is one glaze however that I have used
under shino's, as well as over shino's It is that cone 6 high iron glaze
with gerstley. . .I have used that on rims and with brush work, sometimes
it comes out very beautiful . . . almost gold in appearance.
Hope to see many at NCECA.

Hello Ben,
Looking at the recipe, it has more soda ash than I remember.
*Penn. State Shino*
C/10 R
Nep. Sye. 14.6
Soda Ash 7.8
EPK 9.7
OM4 4.9
Soda Spar 34.0
Spodumene *29.0*
100.0

Years ago,when I was exploring shinos, Craig Martell suggested that I put
more alumina in my glaze to enhance the color. So I adjusted Malcolm's
glaze (replacing half the EPK with fine alumina hydrate), and it is what I
use now. It did not however seem to enhance the color, but did make the
glaze "fatter". The technique that I sometimes use with this glaze to get
(if I am lucky!, black dots surrounded by halos), is to dip it in the
glaze, let it set up a bit, then give another light spraying of that glaze.
I then would stack the kiln the day of glazing, turn on the pilots for a
few hours and then start my firing overnight, setting my forced air burners
on low until the wee hours in the morning.

*Malcolm's adjusted C.T.Shino C/10*
*
*
Nep. Sye. 38.6
Soda Ash 16.3
EPK 8.5
Alumina Hydrate 8.5
OM4 13.0
Soda Spar *9.3*
94.2 (I know, does not add up to 100)

I will do a test when we fire using a thin temmie under these shinos, would
love to get that effect you are talking about.

They are two totally different glazes. The original Wirt Shinos
are somewhat like the traditional ones. But the Davis C.T. are in a
different category altogether.

Yes, you are right. The subject line should have read, "my take on C.T.
shinos". However, if you had read my post, you would realize that I was
talking about shino's with soda ash, the americanized version of japanese
shino.

Thanks for posting your current recipe.

You put it on bisque. I have had good luck on near green (A bisque
that shut off at 800*F. Damned computers!)

What works really well (I learned this from Jim Robinson through
John) is to add iron to some of the Mino, and brush that on before you
dip the regular on top of that. Get some fantastic reds.

Alumina Oxide is pretty expensive.

Ben,
Thanks for the info. That is the wonderful thing about CT shinos, it
reacts so beautifully with just a little bit or a lot of iron in the
claybody. I too have been firing shinos in a wood kiln, and have found
that the CM book on wood firing is great. There is a glaze in there that
reacts beautifully with wood and ash, a nice orange on porcelain, which is
the clay that I primarily use. Can't remember the name, will have to look
it up.
