Looks like I've moved into the clay department now, lol!

Decided to name this little guy Tobin. This is the first time I've ever used super sculpey, and I LOVE IT! The only thing is I don't know about the baking part. I did, after all, sculpt it on top of a glass bottle, and I don't think the glass bottle would survive a bake. What can I do to harden the clay?
