The series of tests I made earlier this month on crystalline glazes appears
to have much improved my faulty glaze batch (by doubling the amount of
kaolin in it). I tend to think of pottery firing compared to cookie
baking--you get undercooked, overcooked, and just--right cookies by just
varying the baking time (or temperature) a little bit... You can also
change the baking time by adjusting the fat, sugar, and flour content of
the dough... (If the cookies are coming out too runny, add flour...) In
this case, the glaze was getting overcooked, so I added flour (kaolin) to
make it cook at a higher temperature.
