Shrinkage of material is something to keep in mind when making a BJD of a particular size. Too much shrinkage could affect how well your doll parts fit together after the shrink because of warping. So before making a doll using Cold Porcelain, I need to test how much shrinkage the log I made has. From what I have read, Cold Porcelain can have up to 30% shrinkage. That is a lot.
I used the plaster mold I made when I was testing Carving Wax shrinkage. The excess I made into a little ball to also test how quickly it would dry inside and out. I still had a little more left over which I played around with and make a 5 petal flower, not shown in the picture above. The line on the plaster mold is approximately 50mm in length.
Now I play the waiting game to see how much shrinkage my goofed up recipe has.
