Cher Monsieur le Docteur
Zinc zirconium silicate is like Tantalus' grapes to me. A zinc source which
doesn't have to be reground to avoid granules in the glaze and an opacifier
to boot. But the esthetics are just out of reach. How to get a white glaze
which is not too shiny or too white. This may not be your esthetic goal for
these glazes but for me I'd look to add some MgO to matte the surface or
some dirty material like wood ash to break up the whiteness.
