Wilton Molds

Wilton has a wide variety of silicone molds.

They are Fondant and Gum Paste Molds and so they are food safe.

I am happy to announce, yes you can bake polymer clay in them.  I tested at 275° and the clay popped right out afterwards.  The mold didn't discolor although this is just one baking.  There doesn't seem to be any degradation of the silicone mold.  I would feel safe baking in them on a regular basis.
