HOW TO MAKE FLAT STRIPS OF CLAY WITHOUT AN
Make a simple device to roll oil based clay to
an even thickness.
when making a mold box, or walls to contain a moldmaking
material, you need to make flat strips of clay. If you do
this a lot, you can get a piece of equipment called an
"extruder" that forces the clay into long strips of most
any shape. Be aware though, that most extruders are made
for forming soft water-based clay. It takes many times as
much pressure to extrude an oil-based clay, and most
extruders can't do it. Ask before you buy.
an easy way to get strips the size you need: just roll
it out with a rolling pin, using some strips of wood or
dowels to act as thickness gauges. If you use 1/2 inch
diameter dowels as your thickness gauge, you will roll
out a strip of clay 1/2 inch thick, and so on. You can
use a larger dowel (1 inch or so diameter) to act as a
rolling pin if you don't want to use a real rolling pin.
Use water as a "release agent" (with oil-base clay) so
the clay doesn't stick to wooden rolling pins or dowels.
When the clay is the right thickness, just slice it into
strips the width you need.
a homemade clay-rolling setup made on a plastic cutting
board. Some metal strips were used so the replaceable
wooden dowels wouldn't shift around. This lets you swap
out the dowels and roll clay 3/8" thick, 1/2" thick,
5/8" thick, or whatever thickness the dowels are. You
could use wood strips instead of metal, or make
permanent thickness gauges from wood if you always need
the same thickness of clay.
final tip: you can use some silicone-coated parchment
paper or a silicone baking mat under the clay to keep
the clay from sticking to your work surface. You can
also get silicone rubber rolling pins. These items are
sold in many grocery stores, or the cookware sections of
