For the past 12 years I've been, intermittantly, trying to come up with a=
particular glaze that I've had no success with and decided I'd throw it =
out to Clayart and see if anyone out there has any ideas.
Newcomb Pottery was made at Newcomb College in New Orleans, LA. It was in=
existance for about 50 years and during that time there were several per=
iods where glazes changed. The one I'm trying to come close to was mat an=
d only two colors were used--a gray blue and gray green.
Ron and John's high calcium blue would work but I don't know how to "gray=
" the blue. Any suggestions on graying a color?
The best thing about the glazes were they looked like you were seeing the=
m through a fog.
Each piece was individually thrown by a man (mostly Joseph Meyers) and th=
e girls came up with the designs and carved them on to the pots. The clay=
body was high in silica and the pieces were fired to cone 5 in an oil kil=
n. I'm not sure if this helped give it that foggy look.
The designs were varied but cypress and live oak trees with hanging moss =
were most popular. Imagine looking through a Louisiana swamp on a misty e=
vening and that's what I'm looking for.
I've read everything I could find on this pottery. I even took a class at=
Az. St. Uni. in glaze making and spent the whole semester working on it.=
Couldn't get it.
Thanks for any ideas.

My reading of Dinah's request seems to be a little
different than what other people seem to be
reading. The second paragraph (above) makes
me think of a blue or green undercolor with a
translucent layer of clear glaze over top. Something
like looking through a frosted glass shower door at
a colored towel.
Would an underglaze with a mat overglaze that
was cooled slowly enough to allow plenty of crystal
growth give this effect? ( See, John and Ron, I
read your book. )
The shower door look sounds like it could be pretty
cool, especially with the right design work underneath.
Trying to think...

Dinah, I have two suggestions. Three actually, if you don't count just
adding a grey stain. One would be to add nickel oxide, the other to add
iron chromate. The iron chromate will make a greenish grey on its own. Not
sure what shade of blue/grey/green you would get with it plus cobalt, but
I'm sure some shade of blue grey would be possible with some combination of
the two.
