curling up pealing off glazes
Hello, Joy.
I could be wrong here, but I suspect your inner glaze may be too thick. This
is common on large forms as the walls, being thicker, will absorb more
liquid and therefore "suck up" more glaze. You might experiment with
thinning your glaze a bit more than usual.
I haven't had much luck so far with spraying the interior of large vessels
(any suggestions?) and have resorted to pouring them, but haven't had any
difficulties with cracking and peeling so long as I don't get the glaze
excessively thick. It's really a bit tricky.
You waste a lot of glaze, too, if you decide to re-do a botched job. I use a
small pail of water to clean out the rejected glaze, then save the water for
use in making my next batch of that glaze.
I'll be eagerly watching for the suggestions people offer you.

Joy,
I was taught to glaze the inside first, and the outside as soon as
possible. Th reason being that if you let the inside dry then the
moisture from glazing the outside will loosen the inside glaze from the
inside clay wall either in the firing or right before your eyes.Its

Joy,
Cindy mentioned that the glaze may be too thick on the inside of the pot. I
tend to agree. Another possibility is quickly running water in and out side
of the pot. This will cut down on some of the glaze absorption.
