This is the mixture in Cernit.
This and the last post are also leading up to something.
Notice the "not conditioned" Caramel.
This was broken off the block flattened a little and run through the pasta machine on the thickest setting.
Because Cernit has a porcelain effect you can view what happens in all Polymer clay when it is not conditioned. ALL polymer clay should be conditioned, no matter how soft it is.

Conditioning gives you the best results possible for your clay of choice.
