normally i bisque fire to 04, then glaze fire to cone 6 ox. the last
load of bisque never got higher than 07, i think... should i expect
changes if i glaze fire as usual? should i re-bisque to 04? the books
i have don't give me a basis for deciding on a temp for bisque. any
help would be appreciated. tia

If you are using glazes that direct you to apply to 04 bisque....to
witness....I love that......sounds downright Friendly.....anyway, if the
glazes are designed to be used over 04 bisque then it is very possible that
your results will change. Many of these glazes (and underglazes) depend on
the clay already having let off the gassy eruptings that will result in
craters or little white dots which are evidence of eruptions that didn't
heal over.....they seem to get impervious on a schedule that doesn't
coordinate well at all with the clay body's schedule of heaving off this
and that......if I were you I would re-bisque.
Eleanora.......been there, done that.......

Refire them. You'll hate yourself if you glaze them and they pinhole.
Happened to me. I finally remembered that one load of bisque hadn't got hot
enough. Put my mind at ease to learn that my pinholes were from that and
not some unknown source. Good luck!
