I just got through judging the local high school pottery show- lots of young
talent on display! I was drawn to one glaze blend that looked like it might hav
been 2 or three different colors mixed on a bowl. The result included some
luster, some matte, some satin. I asked the teacher if he was concerned about t
result being food safe, and he assured me that he thought it was. All the color
used in the blend were commercial glazes, advertized as food safe.
I'm skeptical. Isn't the result a new glaze, in need of testing as a stand-alon
entity? Please correct me if I'm wrong, but if I'm right to be skeptical I want
to pass the feedback along to the teacher (who hasn't hooked up to clayart yet).
Thanks in advance

Patti,
I just took a Mayco workshop - one in their series of certification
courses for lowfire glazes and the instructor stated several times that
their glazes are only certified food safe when used individually. (They
may be safe when mixed but Mayco has never tested their's that way so
they have no idea what interactions may occur.)
He was talking about mixing within a family of glazes as well as between
families.
