Les,
Here is an Oribe glaze I have been using for a few years. I haven't tried it in
a wood fire yet so I can't promise anything, but in cone 10-11 gas firings it is
delicious.
Oribe Green (attributed to David Shaner) cone 9-11 reduction
29.3 Custer Feldspar
24.0 Silica
21.2 Whiting
7.4 Talc
11.9 EPK (Kaolin)
1.0 Bone Ash
1.0 Bentonite
5.2 Copper Carbonate
It has performed slightly differently for me in each kiln I have fired it in,
but is typically a clear glassy emerald green. I have seen it go red and even
blue on occasion. Most recently, in my current kiln, it has even been
developing small mossy crystals where it is applied thick. Very stunning. I
can also say that I have never seen the glaze run and I've fired it from cone 9
to cone 11.
It is one of my favorite glazes right now, along with a nice iron red and a blue
green wood ash glaze. If you use it in the wood fire let me know how it turns
out. i'd be curious to hear about the results.

Les and others who may have copied the oribe recipe I posted...
I am passing this note on to the list regarding the oribe green recipe I posted
a few days ago. Ron Roy noticed that this recipe had come across the net before
and had not lived up to the acid leeching test. So any and all of you that
copied that recipe down might want to take note.
Thanks Ron for that good catch. I'll try to do some testing and reformulation
on the glaze and post the results to the list. In the meantime, it is a
beautiful glaze and would still be good for sculptural/non-functional forms.
