Casting Slip casting?

To my knowledge slip casting is only used with clay, the type you have to put in kilns. You have a two or three part mold that you pore very watered-down clay, which is called slip, into the mold and turn it about until the clay has covered the inside of the mold completely. After is had dried you pull apart the mold and the casting you made with it is hollow inside.

But I think it only works with ceramic clays.

But I do second the request if someone would explain how to make hollow casts using resine. ops:

 

Slip casting is just used for porcelain. Slip is mud made with porcelain clay (kaolin??).

The slip is poured into the plaster molds, which draw off water, so the clay comes out of suspension near the plaster & forms a shell.


Resin dolls are often poured with another piece to their molds that fills the inside of the cavity.
I believe this is what Donn is doing, so look at his thread on this section of the forum.
He promises a tutorial his methods at some point, too.


Slush molding is pouring in some resin & turning the mold all around so the insides of the mold are coated with an even layer of resin once it's cured.
I suspect it is prone to air bubbles, but hopefully I'm wrong.
