Hi Folks!
Seems I'm once again popping in and out of Clayart - seems to be a
problem with a shortage of time. My husband keeps wondering if I'll ever
get to all the "messages in waiting" and I really should delete them, but
I don't want to miss anything.
Anyway, hope you're all having a wonderful summer. I'm needing help once
again. Since it became necessary to retire the lovely but entirely
unstable and unpredictable 3-D White, I've been looking for another glaze
to take its place. I do now have a wonderful stable white dinnerware
glaze (thanks again, Ron - it's still working well!) however, these are
the characteristics I'd like to find:
-glossy white cone10 glaze - reduction or oxidation, doesn't matter
-no crazing
-takes oxide brushwork well
-(and here's the hard part) - fires with "spontaneity" - colours stay
more or less where you put them but have a tendency to bleed a bit
-glaze has kind of a wonderful "fat" look to it - that probably
doesn't make sense but I don't know how else to describe it.
My fear is that the characteristics I've described belong only to
unstable glazes which are unsuitable for dinnerware - which is what I
want to use it for.
I've tried adding frit to both the glaze and to the stains - although
this was moderately successful, it didn't quite fit the bill. I've tried
increasing the amount of gerstley borate in the glaze itself - no success
- added to which one has to be careful that the glaze doesn't slide right
off the pot!
I'd be eternally grateful to anyone who can help here.
TIA
Barb

Barb:
The following glaze meets all your specs except the one about crazing.
It's a good glaze that I formulated in my Ceramics I class at University of
Central Oklahoma way back there. It is very dependable, doesn't run, you
can use a brush over it or under it (with a bit of understandable muting),
colors stay in place, it's glossy, I use it in reduction but in oxidation
it loses a bit of character due to the really white look, You can use it as
a base for wax resist with glazes or oxides over. It's the only glaze I've
used continually for the past 30 years and on many different bodies. I
like it and like what it does. If you try it I hope that you like it too!
Hanlin's Gloss White
Custer Felds 33
Barium Carb 16 (There's that ingredient again, I
haven't tried the .75 Strontium Carb
actor but don't think it would make much difference, if you try it I'd
like to know the results)
Whiting 13
Kaolin 12
Flint 25
Ultrox 8 I've tried other opacifiers, all seem
to be the same chemically but I've
always liked what Ultrox did on this glaze.
Enjoy>>>>>>>>>>>
PS...Take Rhodes 32, color it with 1% cobalt oxide and 4% red iron, apply
it over this glaze and get a really neat semi-mat blue. The white sort of
bubbles through the blue and it's pretty.
I guess by now you maybe think I like it....OK I DO

I have a gloss white glaze from a CM articleon the Sycamore Pottery in
New York (?) several years ago. They used it with a cobalt stain brush
design over the glaze on dinnerware. I find it to be craze free. I could
see someone calling it "fat"or " thickness enhanced." Anyway, I have
another 100 messages to go and the formula is out in the barn. Are you
still looking and interested in this glaze. I'll dig it up tomorrow.

Roger:
I left a recipe here for a gloss white a few days ago. But if you'd be
kind enough to post yours I'd like to try it cause mine crazes a bit and
you'n don't. Please put it up.

Hi Bob, I just finished painting the house and got back to my mail.
Here's the glossy, white, cone 9-10 glaze. Let me know want it does for
you!
Whiting 18.19
Custer 50.19
EPK 12.55
Flint 19.07
Zircopax 25.47
This is the Sycamore White glaze from Cermanic's Monthly several years
ago. I round up to the nearest tenth. I've looked more at the surface
quanity of this glaze and love it. I am going to try test the glaze with
different oxides and without the zircopax and see what I can get. Roger
