I used the Sculpey Satin glazed thinned down with water, so yes, it is acrylic. I think I'm going to chance baking it again, it's better than giving her earrings that are going to start coming apart or leaking polymers.
The pieces weren't coming apart per se, I made beads and if I just took my fingernail and pulled them apart, it was completely underbaked inside. After this instance, I worked out how to really keep my toaster oven at a good temperature.
Thank you so much for your advice, I really appreciate it.
I hope I can save her earrings.
