Here's another installment in my ^10 glazes. Like the other set today, I =
fired these to ^10 in 9.09 hours in an electric Paragon Viking kiln, =
which was allowed to cool naturally to around 300 degrees F. with all =
holes plugged. They were applied on a blond ^10 stoneware clay.

Clear, fat, shiny glaze with severe crazing. Bison poor.
The next three glazes are some which Ron Roy prepared for me to use in =
an experiment. (More on that later).=20
Thanks, Ron. I think any of the three would work great, but I'm favoring =
the second one.=20
I'll call them RR-A, RR-B, and RR-C
RR-A ^10
Ron Roy
#12
Custer Spar 36 (Ron recommended G200, but I didn't =
have any)
Wolastonite 80
Frit 3134 6
EPK 12
Silica 23
Very clear, glossy, NVF. Bison good. Somewhat fat, no drips.

Talc 7
Frit 3134 8
EPK 14
Silica 22
Si:Al 10.33
SiB:Al 10.57
Expansion 6.57
This is a half and half mix with RR-C, which follows. I believe I like =
this one best. It has the fattest appearance, and though it appears to =
be nice and thick, there are no drips. Bison poor, NVF.
RR-C ^10

Expansion 6.70
Buttery clear gloss. NVF, Bison prominent. I suspect I was supposed to =
add Zircopax or some opacifier to this one, but I didn't see it in the =
post from Bamboo Karen. (BTW, Thanks, Karen) Very nice glaze, which =
would undoubtedly make a lovely opaque white with around 15% zircopax.
