I am posting this from rec.crafts.pottery

I'm stuck on translating any of this at the moment, but will try if you
don't get the general gist of it.
These are the glazes I use.

The one I have most problems with at the moment is 101 with a glaze
improver
over. The improver - number 100 - makes it go different blues and greens
and
blacks when I add it on top. Fantastic colors, but the bubbles keep
showing
up. Mind you, I had a bubble on a matte glaze - 404, I think - on this
last
high firing. I don't have this problem at all with low-fire stuff - at
1050
C, same as my bisques (that way I can mix them a bit and get a full kiln
faster).
