porcelain slip cast into 4 part rubber mould

Recommended Posts

You would probably end up with a moldy mess by the time the slip dried enough to pop out of the mold.  The plaster mold absorbs the moisture out of the slip, it would take months for the slip to evaporate in a rubber mold.      Denice

Rubber molds often called master molds are for making waking molds from Plaster. 

I have made many a working mold from a 4 piece rubber mold. You do not use slip clay but plaster in a rubber mold.Then once you have a plaster mold you can slip cast in that.

You could try packing a layer of firm clay into the talc-dusted mold or mold parts , unmolding as soon as possible to join and dry, if you just want a one-off piece. The rubber will not allow the clay to dry, but might be flexible enough to peel from the clay. Expect distortion which might be repairable because the clay is still damp.
