Tip #32: Impressing Patterns in Clay
There are many ways to get interesting patterns in your clay.
Look around your house, your yard, and especially your kitchen, and
you will start to see all kinds of things that can make good textures.
Rocks, the bottom of your shoe, the wheel of a toy truck, a meat
tenderizer, a piece of driftwood. The list is infinite.
But here are a few additional ways to make more complex
patterns.
1. Bisque rods. Make a bunch of coils of clay. For example, a good
size is 1" diameter and 8" long. The main problem with bigger
diameters is the time it takes for the clay to dry before firing. But
you can sit these aside and let them dry for a good long time. While the
clay is still soft, carve or press patterns into it. For example, poke
the end of a needle tool in to make holes. Or press the edge of a ruler
in to make lines. Cover the whole surface with your pattern. After
drying, bisque fire the pieces. Now you can use these rods to make
patterns in wet clay. Simply roll your rod across the clay, pressing
while you roll, and you can make long, continuous patterns.
2. Take wood dowels and apply patterns to them with hot glue. When
the glue dries, the dowels can be rolled across the clay to make similar
patterns.
3. Wrap string, twine or rope around a dowel in straight or criss
cross patterns. Roll over the clay.
4. Carved Linoleum. I got this idea from a potter who used to be a
print maker. Linoleum was used for flooring before we had the vinyl
floors of today. Linoleum is a mixture of linseed oil and cork. When
heated it becomes soft so you can carve into it. Then it hardens when it
dries. You can get linoleum at art supply stores. At the same time, you
can buy a set of Speedball linoleum carving tools for about $7. Either
draw or trace a pattern on the linoleum, then carve it out with the
tools. You can use very intricate designs, such as a tree with many
branches and leaves. The textures transfer very nicely to the
clay.
To transfer the pattern to a slab, put the pattern on the clay and
press with your hands or a roller.
You can transfer the pattern to a cylinder as well. This is very cool
for putting texture on thrown and altered forms. The cylinder should be
stiff enough that it doesn't collapse, but soft enough to take the
pattern of the clay. Place the carved piece of linoleum face up on a
table, hold the cylinder sideways, and slowly roll the cylinder across
the pattern. While you are rolling it across, use a smaller roller
inside the cylinder, to press the side of the clay cylinder into the
linoleum. The mini-roller works really well for this, or the pony roller
for larger areas. They can be found on this page. Handbuilding
Tools You may find it useful to mount your linoleum onto a piece of
masonite or plywood to keep it from breaking.
*** General note, especially for beginners: Non-porous surfaces, such
as plastic, metal, etc. will stick to wet clay. This can make it
difficult to get clear patterns. Therefore, the best materials for
impressing are porous materials such as wood, bisque clay, and plaster.
If you are using a non-porous object, try putting a thin piece of cloth
between it and the clay, or a piece of Saran wrap.

Hi Cindi!
I am know as the "Leaf Lady" by people in the Dallas, Texas
and southern Wyoming area. I specialize in leaf tiles. See my website at
http://www.tileswithstyle.com/
I find that the best imprints are made by herb leaves, due to their
unique vein structure. My Texas garden was dedicated to making
tiles-over 60 varieties of herb plants. Fig leaves also make very
interesting floor tiles.
