I'm looking for a workable midrange porcelain for wheel, hand building, and
slip-casting dishware, large and small, and sculptural vessels. I would lov=
e
to be able to find a slip cast body that is strong enough to allow further
manipulation and add-ons.
Thanks,

Centa,
I have for years worked with porcelains designed specifically for slip
casting. I have also worked with plastic porcelain clay bodies designed
for throwing. I have never found a porcelain that did both tasks equally
well. In my experience they work either best of slip casting, or best
for throwing/handbuilding. The composition of each is different from the
other in order to achieve the characteristics best for one method or the
other.
For throwing, I like Standards cone 6 plastic clay body, readily
available through many pottery supply houses.
For a slip casting porcelain body - I use a premixed porcelain slip
that I get from _Colorific Porcelain=AE and Laces_ out of Lynnwood, WA,
Phone: (425) 743-1591. I have never found a porcelain throwing body
that makes up into a good slip - a lip, yes - but a good slip, No. The
website is here: http://www.colorificporcelain.com/

Centra, the best way to approach this question is to talk to different supp=

You will also need to consider your glazes carefully, since not all glazes =

Therefor my advice to you is to talk to different suppliers and find out wh=
