Thank you to everyone who tried to solve this mystery for me. I received many
answers to my query about what it could be that thickened up the glaze, here
is the list: Most guessed CMC (which several people said also thins the
glaze?), liquid fabric softener, epsom salts, bentonite, tsp (tri sodium
phosphate) and the artists' medium, acrylic gesso.
I had previously written:
Yesterday I visited a "slip cast" commercial pottery that makes the ware
florists use to put their arrangements in. They fire everything to cone 05,
bisque and glaze fire both.
During this visit, the owner showed me his glazing area, with these vats (of
about 8-10 gallon capacity) of glaze they dip the ware in. He asked me if I
mixed my own glazes and and when I said, of course. He said he wanted to
show me his "Magic Solution" for thickening glazes. He stirred up a batch of
glaze and added about 1/2 to 1 cup of a heavy cloudy liquid from a squeeze
bottle, continued stirring and the whole batch of glaze thickened up
instantly for a thicker glaze application to the pieces they were dipping.
Then he said, Ok, now if he wants it to be a thinner coat of glaze for the
remaining pieces, he just stirs in some liquid (which I correctly guessed was
Darvan 7) out of another squeeze bottle and the glaze went back to its
original consistency.
He wouldn't tell me what his "Magic Solution" was, but offered to sell me
some at what I felt was an exhorbitant price.
Any guesses as to what his "Magic Solution" is?

epsom salts
or calcium chloride...
flocculants...
as opposed to darvan 7 a deflocculant

How about adding Calcium Nitrate?
