Have a vase, I'd like some of you guys to look at, and tell me, if you can,
what the reaction is these glazes are having. This is a B-mix clay, dipped
into Antique white (Peggy Heer's) and then half dipped in Sana green
(recipes below).
The pink halo (visible in the photo of this pot, url below also), was a
surprise to me, being in oxidation. I'm still not sure what caused it and
I'm curious.
Most recently I've slip trailed the Sana over the Antique white on amador
bowls and a wonderful milky green/pink marbley look happened. Definately
pink. OH, and it also hinted some pink when I trailed over Fall's Creek
shino. By itself it is a jade (sort of) green, which is also my /pots page
if you look at tidalpoolplate.jpg no hint of pink alone. Thanks in
advance, for anyone who might reply to this.
