Gail,
The following is a glaze I have been using for a year with pleasing results.=
I
found this in The Complete Potter's Companion, by Tony Birks. This glaze is
smooth and satiny, not glossy or dry. The book gives this description: =
=22This
handsome dark green glaze with a very smooth surface has small black =
mottlings
where the copper oxide shows its strength. The addition of 1percent cobalt
oxide and 1 percent tin oxide instead of copper makes an equally rich =
blue.=22
To get the black mottlings I double dip my pots. Here it is,
Dark Green
oxidized 2,335F
1,280C
48 feldspar (I used potash feldspar)
22 china clay (I use EPK)
20 whiting (calcium carbonate)
10 flint (silica)
3 copper oxide
This glaze has the warm look of a reduction firing, which is a nice surprise
coming from an electric kiln. If I could remember how to hook my digital =
camera
up to the computer I would send you a photo of one of my pots with this =
glaze.
Maybe I will find the time to figure it out.

Can't fire it with my regular firing because it' a ^9 glaze...ask how to
make it ^6 >>
As noted, a friend of mine is asking how to change this to a cone six glaze.
Would appreciate your help.
