Lee,
Those to potters make lovely pots.
I met Muira Koheji a couple of times. He was a very nice man. Made
wonderful pots. I doubt that anyone put food in his pots since he was a
Ningen Koukuhou (Living National Treasure). He was the head of Ceramics At
Tokyo Geidai (Tokyo National University of Fine Arts and Music). He visited
Iran, I think, and that trip and an influence on his work for many years.
There is a type of crazing that crazes in a way that the crazes are almost
parallel to the glaze surface. I think that they are called fish scale
crackle glazes. I remember after living in Japan I showed a pot to one of
the lists glaze experts who for the first time in my experience was
dumbfounded. He took off his glasses and tried to crawl into the glaze
after a couple of minutes of looking at the glaze he finally admitted that
he had never seen anything like it. Then he recovered and joked he could
make a suggestion to get rid of the crackle problem.
Crackle glazes and crystalline glazes are but a few of the glaze "defects"
that can be made into an advantage. Crawling is another.
Happy holidays,
Rick

Rick,
What about pinholing!? There are great shinos and temmoku's (pigskin) with
pinholes. Some are even have the defect "orange peel". How about puckering
of the glaze (Happens with teadust glazes which have too much slow cooling
and the entire surface starts to pucker up). Same thing happens with you
over reduce iron glazes - they get really "crusty". Then there are pop
outs (aka feldspar or granite in claybody). Or bubbles in the glaze?! And
as you said surface tension/crawling, crazing /crackling, crystalline
(running), etc.
So many glaze faults are fantastic. Just not enough time to try them all.
Merry Christmas,
John Britt
