a while ago someone posted a Persimmon Glaze recipe (recipe follows). they
said it would give a reddish-orange--persimmon--color at ^6 and when refired
to 06 would show some beautiful blotching and shading. Well, they were right
and it was wonderful. looked absolutely great on a mask I made. it's been
sitting on my shelf for almost a year and when I used it recently, it only
came out a brownish, honey, uninteresting color. No matter what clay I used
it on, white or brown. my question--could something have happened to the
glaze while sitting--deteriorate or what? I didn't know this could happen to
a glaze, but then until I watched Emeril I didn't know spices went bad
sitting on the shelf either.

Lynn,
I haven't seen any responses to your persimmon glaze question, so I'll
venture a guess. This glaze has a very high level of Gerstley Borate, which
is high in solubles. GB glazes can tend to change over time and it is
generally best to make them in batches of a size which can be used
relatively quickly. This is one reason people were calling this ingredient
"Ghastly Borate" until we got the word it would no longer be available.
Then, suddenly, it seemed precious as gold.
