green-blue cat mug

Beautiful! How did you do that? Did you use white slip underneath, for the cat?

Thanks!  Well, sort of.  The cat is a cut-out resist of thin plastic, put on the porcelain body.  Then the mug was dipped in a slip made with added titania, which alters the blue glaze slightly in color and texture.  The resist is peeled off and details sgraffitoed into the image, then bisqued and fired.
