Slip Casting
A Simple Ceramic Mold.. You
will need: An "open cast"
ceramic mold (plaster), ceramic slip, towel for
spot clean up.
Open cast ceramic
molds are a pour and
walk away variety…
there is no need for a
dumping receptacle for
slip. Which makes this
type of casting neat
and tidy.
Pour
slip slowly into each
cavity of the ceramic
mold. Fill all
the way to the top.
The
pieces are ready to
de-mold when the slip
is no longer liquid
and the edges of the
clay have begun to
pull away from the
sides of the plaster.
Time is about 30 to 45
minutes depending on
the humidity in your
studio.
Pick
up the ceramic mold,
and as shown slightly
tap the mold, to
release and loosen the
clay. Remove the
disk and place them on
a flat surface to dry.
Enhancements
to wet clay. To
place a top hole in
the disks, use a
plastic straw for a
clean cut hole.
To create a frame
disk, use a cookie
cutter to place an
opening in the disk
center.
Using
a damp sponge, smooth
the edges. Cast disks
are already beveled so
there is very little
clean up.
Allow to dry
thoroughly..
