Roma Plastilina

[rollerboi]

I have a huge brick of Roma Plastillina clay left over from a sculpting class I took awhile back. I was thinking about using this to sculpt a large-scale project I have, but then I realized that, chances are, it has sulphur in it.

Is there any practical use for this clay for us? Any good alternative way to cast it up? I hate to just let a good raw material go to waste.

You could try a hydrocal mould and then make a resin positive that would both be a master and a base for a silicone mould.

I still use Roma Plastilina which contains sulphur, since I bought a lot of it a while back and have just been recycling it.
All you need to do is to seal it well with some Krylon clear coat and you can use any molding compound you want including silicone.
What I normally do is prime it, then clear coat for more of a barrier from the sulphur.

Use GI-1000 from Silicones Inc. It laughs at sulfur content!
