Hey, supercool!! .... eat this kind of thing.
The reason your pieces darkened can be one of several:
clays (original Sculpey, SuperSculpey, Sculpey III) darken more easily than other brands. This is particularly true for their lighter colors or any colors with translucent in them (which can include even the dark colors)
like these don't need as long
a bake as regular size items... theoretically, all clays but those Sculpeys could stay in the proper temperature for hours and hours and never darken, but it can be hard to make sure the temp never
gets higher; next time try only about ten minutes
in the oven, or next to the clay, can be hotter than you think
.....unless you measured the temp with a separate oven thermometer, it may not actually be the same temp that the dial is indicating
.....you may have baked on something which will heat up more than the ambient temperature in the oven, like metal or ceramic tile
.....your bone may be too close to the bottom coils or to the sides of a small oven, or even in a "hot spot"
There are ways to avoid all these problems though. Check out my page on baking polymer clay for loads of info about all of them:http://www.glassattic.com/polymer/baking.htm
I wish the polymer clay "microorganism" unicorn zombie apocalypse was still online for you to see! Turns out there are quite a few scientists and science types involved in polymer clay, and these guys created a unicorn zombie apocalypse for items which might be found under the microscope; they were really great!
....There are other people in the science field (including nurses, researchers, etc.) who eat various micro-organisms, parameciums, etc....and eat to use them as jewerly, pens, etc.
... Once he and I made some pinworms from clay for a "joke" presentation to a research doc. The doc loved them so much they hang right next to his Nobel Prize!!! syndee
...sanguinia's polymer clay maggot or grub (as pendant)... made out of translucent clay with a dab of ivory clay (roll into a thick snake and then start twisting. ...smooth off the "head" part, and pierce a hole through it side to side....bake) ... I also made a "lovely larva" too using some orangey-brown and ivory clay.

...my son just made a good-sized brain from polymer clay for a school project... it had many of the various parts in different colors, then he sat the whole thing in the top of a plastic Halloween skull as his "presentation". Diane B.
