Nope, those are earthy clays, I've never had any luck with that. I use Super Sculpey, which is a polymer clay, and doesn't dry out like earthy clays do. It's a lot more manageable. And Super Sculpey is baked in a home oven, it gets ruined by kilns. Which is unfortunate in a way, because not much can fit in a home oven and limits the size of the sculpture 
Ah, now it makes sense how you were able to put so much great detail into it. I Super Sculpey fairly affordable? I've wanted to do ceramics or pottery at my house but all I would be able to do is this one method where you get bisque ware ( I think that's the one. Not sure been a year since my classes) and put it in something like a trash can along with papers and things like that. It gives it an interesting finish. I think it was something like Ragu or Rago. I'll have to look up that stuff though.
Well, it's not exactly cheap. About $22 for a pound of it, roughly twice the price of regular sculpey. But it's definitely worth it.
man that's pretty high. but it never drys out till you put it in the oven right?
Unless you're going to leave it out for a year, it'll stay soft and workable until it's baked. But even if you leave it out for a loooooong time and it starts to dry out, there's a special super-sculpey liquid you can buy that moistens it up and stops it from crumbling.
Realized I left this message floating. Thanks for all your help
