Hi Everybody,
I am looking for a glaze that is deep green like dark green marble.
Does anybody have a deep green glossy (not satin) ^10 glaze for
reduction that I can use on porcelain? Actually, if you have this
color glaze for any cone, atmosphere or clay body I would appreciate
it. Thanks!

Hi Student...no name....
Here is a dark green shiny glaze that I used when I was doing porcelain ^10
reduction....It is beautiful especially on texture.
Rene' Ben Lisa (France) ^10 Reduction
Feldspar (potash) 60
Whiting 15
Flint 25
Kaolin 5
Barium Carb 5
Add 5% yellow ocher and more if you want a deeper green
Add 10% red iron ox. for a temmoku
I know it does not add up to 100...try it anyway.
On stoneware it is a bit bland for my tastes but on white stoneware or
porcelain its a beauty. It comes from Peter Lane's book "Studio Porcelain"

Here is a green glaze I use. This base glaze gives great color response.
Cone 10 Reduction
5 Bone ash
9 Gerstley Borate
5 Whiting
67 Kona F4 Soda Feldspar
14 Flint
Add: Zinc oxide 5%.
The colors you get will depend a lot on your claybody and your firing
schedule.
Colors:
For dark Speckled green on stoneware, hunter on porcelain add:
2 % red iron oxide
.25 Cobalt oxide
.50 Chrome oxide
Another beautiful green would be to add:
1% red iron oxide
.25 cobalt oxide
1 chrome oxide
5% Tin oxide
For a great warm, speckled, reddish brown, add: 2% Red Iron Oxide and 2%
Copper Oxide.
This base recipe makes a good blue celadon with the addtion of 2% Black Iron
oxide. If you want it bluer you can do a variation with 1-2% black iron
oxide and .25% cobalt carbonate.
It is also a good rutile blue with variations from 1-4% Rutile and !-2%
Yellow ochre, or Red Iron. oxide.
This base is also reactive with copper so you can get nice flashing with just
a hint to copper brushwork on a pot on the celadon colors.
You may want to do some variations using another sodaspar as well.
