These marvelous mugs pulls the eye in a downward spiral. The first one is representative of my old style of dipping the rim of the mug in the coloured glaze.
The next mug indicates my newer style of leaving the external portion of the mug more pure with only clear glaze over an image. This not only allows me more room for the image (hence, a larger image) but it also provides a greater contrast between the black of the image and the natural colour of the clay.
