The shield-shaped sunface motif slide is a tufa casting. This method requires the artist to carve the subject image in reverse, creating a two part mold into which molten silver is poured and allowed to cool. This tufa casting required a signature mark to be carved and matched, or aligned, with the image half.
Ric Charlie cuts marks in these stone halves, so they can be matched perfectly before being wired together for the pour. After being pulled, the casting is detailed by hand, using saws, files of various tooth and sanding papers or wheels. Serious polishing is done to bring out depth and texture. In this case, background was oxidized to enhance its dramatic effect.
Jet was cut and flush inlaid for the eyes and turquoise for the mouth. A clear, red enamel was applied to the lower face, giving the sunface distinct and separate life from its background.
