A follow-up to my own post.
When I read Tony's post my attention focused in on "I had a student refire
some dog shino in electric and get very nice orange colour in the craze
lines. so i can undertand colour developemnt happening but i'll be damned
if i can figure how the glaze melt can be altered." So I discussed refiring
in my response. Upon re-reading Tony's post I see that the issue is more
about a mid-temperature hold during the cooling. I would assert, though,
that the same factors come into play. The hold allows the high temperature
interactions to continue. Once melt has been initiated at higher temperature
it can be sustained at a lower temperature due to the intimate contact
between the constituents (perhaps soldering would be an appropriate
analogy). Also, diffusion is certain to occur.
Sorry for the confusion.
