Thanks Tony, now I don't think I'm quite so crazy. In the
last couple
of years I've tested hundreds of glazes - testing, altering,
retesting, more altering, overlapping, and on and on. I
thought I had
one that worked - a turquoise glaze, but it needed a liner
glaze
because it wasn't food safe and seemed to be putting to much
copper
in the kiln and messing up the shinos."
I posted earlier about experiencing a similar messing up of
shino's
I finally moved all the shino pictures in one album to make
it
a bit easier for viewing.

I did use a bit of wax resist over some of the pieces to
promote
some of the trapping, but this glaze fired on it's own
without copper in
the kiln is very orange. These pieces were different from
previous firings
of this glaze, not so much on the stoneware but definitely
different
on the porcelain, seemed like almost a fuming effect.
I am wondering if there is an explanation for the copper
reds in the kiln changing
the whole appearance of the shino.
