Porcelain bowl with carved design and celadon glaze by Karl Martz, 1975.

1 3/4 inches (4.4 cm) tall; 5 1/4 inches (13 cm) wide.
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).
