the process you are describing sounds more like making a core for an animatronic skin as opposed to a mask. In that case the sculpt is made first, then when the mold is popped and the clay is cleaned out a half inch of clay is put in the mold and a fiberglass or plaster core is made from that.
I have no more time to dig (I have moinkey to mold) but I will look later in case thats not it.
