Carole,
I only recently became aware of CadyCal100 (it is listed as an ingredient=

John Hasselberth=92s GlazeMaster 2.0 (GM2.0) computer software. I became=

intregued with it as a replacement for Gersley Borate. I have tested man=

other non-ash glazes replacing Gerstley Borate with CadyCal100 (making sm=
all=20
changes to the unity formula) with no noticeable adverse affect. I have =
not=20
yet made the same switch with my ash glaze, although, I believe there wou=

be little or no problem. I did replace GB with CadyCal in GM2.0 and foun=
d=20
minor changes (in unity): Cao went from 0.602 to 0.623, B2O3 went from 0=

to 0.094, and both Alumina and Silica went down a little bit. These are v=

little changes to this glaze. So, I think if there is a noticeable chang=

it will be to make the glaze a bit more runny. I hope this helps,
