I mainly play around with Chavant NSP medium. There is no sulphur in it, which helps your hands and makes things easier when it comes to molding.Thanks man and one more question, how many lbs would you advise getting to make a head? Like a face and bio...hmm I should learn how to cast shouldn't I?
Not all oil-based clays contain sulfur. In fact, if you're going to do any silicone molding, you'll want to stay away from clay containing sulfur, because it inhibits the cure of the silicone.Wed clay (em-217) is good clay if you can buy it locally. Its cheap $25 for 25 pounds just expensive shipping. Chavant clay NSP soft is good as well. Medium takes allot of kneading to get it workable. Ive used roma clay... got a ton of it cheap at Pearl arts and crafts. If you are planning on doing allot of sculpting I was told that oil based clay is bad for your hands..... (the sulphur)
Brandon, have you ever tried Plasti-Paste for a mother mold-- works great and you can use it over and over again with no worries. A bit more expensive but worth it in my book if you are keeping the mold. Just sharing info Brother!Molding is a whole other story. If you're making a latex mask, you'll need some UltraCal or HyrdroCal. There's lots of info on the site about that, and you can always ask more questions when you're closer to that point.

I haven't actually. I've looked into it a few times but when it all comes down to it I'm pretty much a molding Virgin. I've got a lot to tackle in the next few months so I'll definitely keep it in mind. I must have been mistaken though, I had always thought that plasti-paste was more suitable as a support shell. I didn't realize it could be used as a mother mold. Good to know man, thanks for the tip! I don't imagine it being very porous, do you have any experience using it with Latex? Or do you use it when casting in another particular medium? Knowledge is Power B)
Straight from the Smooth on Website...A mother mold is a support shell
Suitable as a mother mold / support shell (reinforces shape of rubber mold during casting)
