Dear Scott B. Ackerman,
Zinc silicate has to form from the mixture. To get this to happen all of =
the ingredients have to go into solution. It is important to ensure that =
all of the zinc oxide dissolves before the Willemite starts to =
precipitate. You rely on the glass in the frit to keep everything in =
solution as the melt cools. Crystals seem to grow best just above the =
glass transition temperature.
Others may have a different answer.
Best regards,=20

Dear Dannon,
I suppose you will have been told by now that "Glazes for Special =
Effects" by Herbert H. Sanders seems to have been the fore runner in =
this field.
There should be prime references in any book. This one has a couple of =
early ones from the Journal of the American Ceramic Society. I'm =
surprised Saunders in not mentioned in the books you speak of.
All the best and have fun,
Ivor Lewis

Ivor - Those books were not written when Sanders published his
"Glazes for Special Effects". The only other book I could find
besides Sander's book at the time (1975/76) was Taxile Doat's "Grand
Feu Ceramics" and that was a translation in Library of Congress. I
had written to Herbert Sanders and he kindly provided me with
references.
