I have been working with these 2 different glazes for awhile and just
tried them together and it's a good combination. I have used said
combination on several pieces w/ good results.

Last week, I made a 3-canister set and glazed them by dipping the top in
glaze #1 and the bottom in glaze #2, letting them overlap about 1/2".
The largest canister and the smallest came out just fine. The middle
one, however, had one spot on it about the size of a silver dollar where
the glaze turned white, matte, and cracked like the desert. This glaze
is PURPLE everywhere else but in this one spot.

So, I fired it again, with a dabble of fresh glaze over the ugly spot
and now the WHITE glaze just below where that blemish was has developed
these weird blisters that look like onion skin, and the original ugly
spot has gone away. I've never seen such a thing before in my life, and
it's REALLY weird looking.

Anybody got a clue what's going on here?
