Materials Cold porcelain clay?

Hi! I have just had my first try at homemade cold porcelain as well. (My recipe was similar to yours.) I made a few pieces to test the durability of the material, a pearl, a long, thin tube, a hollow half sphere. I also cast a face using a mold I had made for the SD heads I sculpted.
Here's a photo
Cold porcelain shrinks A LOT. You start sculpting an SD and end up with a slim MSD.
My test pieces got very hard. About as hard as oven-baking clay like Fimo, maybe even harder. I have also kneaded in a bit of oil paint to tint the clay - worked out very well. These are my experiences so far.

Anyone else who has tried cold porcelain?

 

I've used this! Unfortunately, I haven't personally found it very good for doll sculpting. With all the shrinkage, it means lots of cracking when you are sculpting over anything. I sculpted a small torso out of cold porcelain over a core made of tinfoil and paperclay, and when it dried it had cracked so much that it was basically unsalvageable.

However, I had never thought of making casts in it! That might be really interesting for someone trying to significantly shrink down a doll...

 

I've just read a reciepe on Wiki and sounded really interesting.
I've never sculpted a doll (or anything else for that matter). I was thinking about the shrinkage mentioned and thought the core that is used to create the hollow should be flexible??? like clink wrap or a firm foam of sorts??
Do you think these could work??
