I am looking for a transparent glaze to use over cone 10 stoneware. I use
several clay bodies to build my pieces, so I don't want to obscure the clay
surface. And I don't want gloss. A soft satin sheen is ok, but nothing
shiny. Perhaps I could use a subtle color tint on some pieces, like a mild
celadon. Thankyou ,Shelley Potter

Hi.
I am looking for a satin to matte transparent glaze that would work over
Amaco underglazes (fired to cone 6-7). I have tested several recipes, but
have not found one that works well. The most usual problems in my tests are
changes in underglaze color (blacks becoming bluish), underglaze running,
and not enough translucency. Any ideas?

Here is a glaze gleaned from someone at Ron Roy's class at Canador College.
^6 RR Clear Matt #1
g-200 Feldspar 30
Wollastonite 20
EPK 30
Frit #3134 20
translucent, buttery matt
When I tested it at the class over velvet underglazes on porcelain it looked
very good. I am still checking out the possibilities with this glaze, to be
fired this weekend. Still need to do the old RR torture test on it.

I personally haven't tried this one but it is rated at cone 6 and should be
Translucent satin matt
Feldspar custer 48.5
Whiting 18.0
silica 18.5
kaolin epk 8.5
zinc ox. 2.5
mangnesium Carb. 3.0
Bentonite 1.0
As wth my experience in using the faithful Mangnesium Carbonate, make only
enough glaze to get you through your project as it will settle in the bottom
and become lumpy after a day or two. I use a transparent cone ^6 easy EASY
EAsy glaze on a white body that does well that you may want to try a test
tile. It will make raw umber shift a little if it has been bisqued onto the
pot.I have not used underglazes,yet, with it.
Gerstley 50
Kaolin 17.5
Flint (silica) 32.5 Good interaction with clay body and nice
covering
Good luck. Have fun! Douglas Adams

I'm curious. Is there a reason to use magnesium carbonate when you
could substitute dolomite for that and part of the whiting? I've seen
this in other glazes and figured if I found one that I want to pursue, I
would certainly test that, but in the mean-time, figured I'd ask.

Dear Evan,
I've done quite a few tests - reformulating glazes to get different
recipes but keeping close to the original analysis. I can't claim that
one always gets exact replication and I suspect that this is due to the
fact that our analysis of the materials aren't 100 percent accurate
(especially true of the colouring oxides)
However, one usually gets very close.
In the recipe you mention I'm sure that your suggestion of substituting
dolomite for the mag. carb. and part of the whiting will work.
Cheers,
Mike Bailey.
