[Clayart] Bisque

Bisquing temperature practice has a wide range, from none (once fire) to
the highest temperature the ware is exposed to (high end porcelain dinner
ware).  Our “normal studio “ bisquing/glazing/firing practice seems to run
to cone04 bisquing, slurry glaze application, and cone 10 reduction
firing.  It doesn’t have to be that way.

There are stories among elder potters about the absence on non-commercial
pottery information when they started out.  The Leach “Potters Book”,
Rhodes “clay and glazes” and others started to change that.   The build up
of published studio experience since the middle of the last century has
been largely in that 04 bisque/cone10 final firing.  Perhaps this is partly
a result of the energy rich societies of the post-industrial western world;
perhaps the results achieved with the available materials drives these

Generally , people resist change unless or until their current practice
produces unacceptable results.  And not even then sometimes...  A lot of
what is done in ceramics is, because the materials and interactions are so
complex, empirical and even traditional .  Also, as Mel noted, there are
other paths.  However, if one ventures too far afield, the pool of
knowledge and experience shrinks and you can have problems that are
uniquely your own, as will be the answers (if any).  Sort of like the world
without Clayart.
