Porcelain bowl with carved design and celadon glaze by Karl Martz, 1975.
Karl carved into the soft greenware (unfired) body with a broken hacksaw blade.
The greenish colored glaze fills the carved depressions, darkening them.
"U/L" on the foot signifies that this was made at the University of
Louisville, while Karl was Bingham Professor of the Humanities
(see timeline and
paper serial numbers).
