Snail writes<<<<<<between making molds for pottery or sculpture. Be prepared to think in terms
of PARTS if necessary. Cutting the piece apart while stiff leather-hard is my
preferred method. Making the piece with separate parts from the outset is
also an option, and allows
for the creation of forms that would be difficult to make as a single unit.
Parts may be attached while just stiff enough to handle, leather-hard, or
even dry (with paperclay), or attached after firing with epoxy.
To follow on Snail's thread, there is a very big difference in the way you
approach making a mold depending on whether you are planning to press mold or
slip cast. Slip cast work has the advantage of picking up detail well and it
is easy to "glue" pieces together using wet slip. If you want to combine
multiple parts in a specific way, it provides a useful method. It has the
disadvantage of being hard to work with - in that you cannot hand build
uncast parts onto it easily. Press molded pieces are better for work that is
more of a vague idea on which you plan to work from a specific form in a
mutlitude of different ways. With press molding, you don't have to be as
precise in the vreation of the mold. Molds for slip casting must be made very
tight and the process must be planned from the beginning.

Just a note here: the key to greater maneuverability with castings is to
save the scraps from making castings and wedge them into clay instead of
recycling into slip (which has its own problems I won't get into
here). With that clay you can add anything you want to
castings.....handles, knobs, you name it. And you can throw with that clay
(yeah you really can) and add thrown parts.
