Yes it is possible to condition hard polymer clay!
Who would have thought that crumbly, hard clay can become soft and workable! My Cernit Polymer clay was so old and hard and wasn’t fun working with. My hands hurt after a short time working with it and I wondered why everyone on the Internet was saying that Clay gets extremely soft if you knead it for a long time.
I already thought I had to throw the clay away. Because my clay was hard, dry, crumbly and wouldn’t get soft no matter what I did.
I checked the internet for some information on how to get hard clay soft and found out I needed a clay softener. As soon as I had the clay softener I first chopped the clay in tiny pieces with a blade. After that I added some Sculpey Liquid Clay Softener and Vegetable Oil to it and made small balls.
Before I could use the pasta machine, I rolled out the clay with a warm thermo bottle. That’s a handy trick because we have winter down here and although we have a warm home, my hands are not warm enough to get the Cernit soft in no time.
Wow you cannot imagine how relieved I was when the clay went through the pasta machine, because before it was too hard and crumbly and even thin rolled out pieces would not enter the machine.
Just HAD to post this because something that seemed impossible has been solved =)
