Hi Rick,

Just to add to your thoughts,

Best to use a frit that has no alumina or very little so you can add
more clay to the glaze to help suspension.

Unless you need a very white glaze it?s best to use ball clay instead
of kaolin. Ball clay is a better suspender and has less alumina so yo
can get more in the glaze.

Anyone who wants my glaze course book just let me know and I can send
a PDF file. It has a lot of analysis in it.
