I love working with white and translucent clays together. They can be a bit touchy, though. Example:
The longer you bake, and the more you bake, the darker the translucent clay becomes. You can get around it by baking at a lower temperature, but it affects the durability of the piece. I guess I'll have to rethink how I put the pieces together so I can minimize the total baking time. More views:
I put a little glass flower on the inside to help hold everything in place, as well as tie the colors together.
