Most folks bisque at Cone 06-04. If you bisque your cone 5 clay at cone 4,
you will not be able to easily glaze the pieces. 06/04 is a good temp that
drives out a lot of the moisture but still leaves your pieces porous enough
to accept the glazes. Good luck. Steve in Tampa, FL

Is there a general rule about what temp (cone) to fire to the bisque
stage? For
example, is it usually one cone under what you would use for glaze? I have
some
clay that is Cone 5 and it seems I read that you fire at a lower cone for
bisque than when you glaze.
Thanks for answering all my ultra newbie questions.
