The clay body of this piece was made by slip casting in a plaster mold.
The plaster mold was cast around
an original rooster sculpted by Karl.
After removing the original, and drying the plaster, the hollow
in the mold was filled with slip.
is liquid clay. The plaster mold (initially dry)
pulls water out of the slip where it contacts
the mold, forming a leathery skin. When the skin is thick enough, the remaining
slip is poured out, leaving a hollow clay body in the hollow inside
of the mold.
After some further drying, the clay "skin" separates from the
plaster mold, which is then removed leaving a hollow clay rooster, which is
then completely dried.
Glaze decorations are then applied by hand.
How many of these roosters
Karl made is unknown, but probably not more than twenty-five.
Each had an identical body but individual
variations in glazing.
This piece is an example of a few
low-volume production items
that Karl made early in his career.
A similar rooster can be seen at the right end of the wide
shelf in the Pink House Showroom.
