Hi,
I have been reading about refiring and have a couple of questions.
I thought that if I fired at cone 5 and wasn't happy about the results =
that I could refire at a lower temperature like cone 04 with low fire =
glazes. Will the low fire glazes sink into the cone 5 glazes and not =
really cover?
However, some of the postings have indicated that it would be better to =
refire at cone 5 again.=20
If I refire at cone 5, then do I still put on the three coats (brushed =
on commercial glazes) over the hairspray or other material to get the =
glaze to stick?
Can I leave part of the previous glaze showing or will it be overcooked =
in two glaze firings?
Any recommendations?
Thanks

Depends on both the glazes involved. Test!

Depends on what you want. In what way was the original firing
unacceptable? If the glaze ought to have looked better, but
didn't look right this time, you can try refiring at ^5. This
will only help if it was a firing deficiency that made it come
out poorly the first time (like underfiring, or too-fast cool).
If it's butt-ugly at its best, or was mismixed, I suppose you
could try to hide it (sort of) with a coat of low-fire glaze.

Eek! Don't do that! If it had the right amount of glaze on it
to start with, it's still on there, and adding more will make
it a double-thick glaze coating. If it was too thin the first
time, by all means add more, but a double-thick coating
(depending on the glaze,) could really run badly.
Please note, though, that when most people talk about refiring
to low-fire temperatures, they mean refiring the same ^5 glaze
coating to low-fire, to simulate the effects of a longer cool-
down cycle. They aren't actually applying any low-fire glaze.
