I've done some testing, and like the way this glaze looks on my Tucker's MCS
c6 porcelain. I omitted the zircopax, and used Mason stains to color small
batches of glaze to use as underglaze for decoration. It works, but what I
don't like is that after sitting for awhile, the glaze and underglaze
batches become hard -- almost like cornstarch in water. After some vigorous
prodding, it does become liquid, but I'm wondering if I could add some
bentonite or something to help keep it in suspension. If so, how much? I'm
finally getting some successful results, and appreciate the advice that
flows so freely here.

Hi Sue,
Yes - adding 2% bentonite will help - best to mix up a new batch with the
bentonite added - stir it into the other dry materials and process the
normal way. Once you have the suspension figured out you can deal with the
old glaze.
If you would like that glaze reformulated to cure the basic problem (the
Neph Sy) let me know and I will send some new recipies for you to try.
