PMC Clay?

I'm really interested in working with this material...I've taken pottery classes and jewelry classes seperately, but I have a feeling this will be totally different! Maybe a merging of the two? I love the idea of forming my own silver pieces without having to use a mold. I dont have a kiln, so I will have to use the torch method....
Anyone out there have any helpful tips for working with it? Considering the price of the clay, I dont want to make toooo many mistakes :P

gracias!
