So as you know, I finally succeeded in making cold porcelain ^^
To recap, the ingredients I used were:
1 cup cornstarch
1 cup PVA glue
2 Tbsp lemon juice
2 Tbsp baby oil
I mixed ingredients together, put them in the microwave in 20 second intervals – for about 5-6 times. (Until I had this lumpy mixture that stayed in a ball when I mixed it around)
Afterward, I spent the LONGEST time mixing. Ended up using about 3 cups of tapioca flour to make it not stick (ran out of cornstarch), and also, figured I was using the wrong cream. Neutrogrena non-grease hand lotion worked perfect for me.
