Subject: [Puptcrit] Help needed with neoprene casting problem


I'm having an unexpected problem with my neoprene slip casting, and 
am hoping someone can help.

I am working with two part plaster molds which I have used before 
with good results. I've always pulled really nice neoprene heads from 
these exact molds. Now however, when I pull the mold apart, the 
casting is stretching along the seam line. This happens no matter how 
careful I am, or whether the slip cast is thicker or thinner. When 
I've finished extracting the casting from the mold, an indentation 
remains where the stretching occurred, about 1/4 inch wide down to 
nothing, and of course this doesn't go away upon drying.

I'll be able to fill the gully and sand away all signs, but I really 
don't want this to happen in the first place since it is a mild 
distortion in the face. I'm completely baffled and really hope 
somebody has the answer.

Let me know! Thank you.
