The only things that comes to my mind as to why your glaze would
crawl is the ingredients in your glaze and firing before the glaze was
completely dry.
Is there zinc in your
glaze or plastic materials that take a while to dry?
and was the glaze completely dry before you fired your glaze firing?
If not the glaze could have started shrinking excessively in the firing and
pulled
away from the clay body. Thus creating a crawling effect.
If the clay body was denser than usual (from a higher bique firing)
It would take much longer for the glaze to dry.
