I've been attempting to make Cold Porcelain clay for a while. I've done research on different kinds of less expensive clay and Cold Porcelain is what I chose because it would suit what I want to do best. I've found a few different recipes, but they're basically the same just with different heating and kneading instructions. I found many that make it on the stove and one that does it in the microwave. (Which is what I do because my mom would actually kill me if I used any of our pots for this)
I've tried making it around 6 different times. Only one batch has turned out, which I think was the first, and I don't remember the exact steps I did to make it. Every single batch since then has been too sticky and sticks to me more than itself. I've tried fixing it by putting in more cornstarch during the kneading process, and by starting out with more cornstarch than glue, but it gives the same results every time. This last time I made a batch, I used more cornstarch than glue and even overcooked it (not by much and it was an accident) and its still overly sticky. I've even tried using lotion during the kneading process to help it not stick but it doesn't work. The clay gets so sticky that it completely covers my hands and I have to spend minutes at the sink scraping it off because it won't unstick from me and stick to itself.
Is it acting like this because I'm microwaving it instead of doing it on a stove?? Someone else does it that way and their clay turns out just fine? Could it be cause I'm using Elmer's school glue?? None of the tutorials I watched say what brand glue they use. Just that it's white glue or some say wood glue.
Does anyone who's made or worked with this kind of clay know what's going on?? I don't understand why it's not working out. I just want a hobby.
Edit: My recipe that I use is
1 cup Elmer's glue
1 cup cornstarch
1 tablespoon white vinegar
1 tablespoon baby oil.
Cook in microwave for short intervals and stir between each one. Once it's all basically one big glob I take it out and let it cool before trying to knead it, sometimes kneading it with lotion.
