Is chalky in application: adding CMC. Glazrite, similiar additive can make
the glaze not only stick better but makes it easier to apply the stains
(which I have also added Glazrite or CMC to taste/feel/stick) Hope this
helps.

Many thanks for the warnings, Ron. I'm just playing around, experimenting
with Majolica. I don't plan to sell any of it, but I will certainly test
the finished product.

The expansion of this glaze is pretty low so it would be best to test
carefully on all the clays you use to see if it is going to shiver. Low
fire glazes do not develope very good adhesion to clays and fit problems
can show up a lot faster. Slivers of glaze in food would cancel out any
food safe rating - instantly.
One of the more serious aspects of painting stains on top of glazes is it
puts the coating in direct contact with food - if the food can come in
contact. If you look at the molecular formula of Frit 3124 you will see it
is barely a stabe glaze at cone 6 - which probably means it's not at 05
although I have no data to back that up. When you add that much stain to a
glaze the chances are you have affected the melt and that affects stability
as well.
The best couse of action - if you don't have the combinations tested for
metal release - is confine the decoration to the parts that are not going
to contact food. At least do the lemon and vinegar tests.
