hrough the Ages
During the Middle Ages, especially in panel painting and in the illumination of manuscripts, the ground was often of gold leaf.
In wall painting, or mural painting, two layers of different-colored plaster are usually employed.
In stained glass, the scratching is done through a top layer of colored glass, revealing clear glass beneath
I
n pottery the pattern is incised through with colored slip, glaze or
underglaze
revealing the clay body color beneath.
Sgraffito ware was produced by
Islamic
potters and became common throughout the Middle East.
The 18th-century scratch blue class of English white stoneware is decorated with sgraffito patterns touched with blue.
Sgraffito ware was produced as early as 1735 by German settlers in colonial America.

We will be making bowls to donate to the Genesee Center for the Arts’ annual Chili Cook Off.
We will make draped, slab bowls.
We will decorate the bowls using a sgraffito technique.
Click on the image to see the Genesee Center for the Arts website.
Slide27The Process:
BOWL
Wedge clay
R
oll out slab to a little over ¼ inch thickness
Use circular template to trace and cut a circular shape for your bowl.
Drape your slab over a bowl that has been covered in plastic wrap.
Do the following:
Make a coil “foot” and score and slip it to the bottom of bowl.
Slide28The Process:
CUP
Wedge clay
R
oll out slab to a little over ¼ inch thickness
Use
curved rectangle
template to trace and cut a
shape
for your
cup.
Allow to dry a bit and drape around a cup for support
Cut a separate circular shape for base
.
Do the following:
Make a coil
“handle”
and score and slip it to the
side of cup.
Slide29Slide30The Process:
DESIGNING IMAGERY
In your sketchbook, sketch ideas for your sgraffito design for your bowl.
You will be working in black and white in a circular format.
Tips:
Repetitive design
Abstract design
Simple imagery
Variable line quality
Contrast in value
