TRANSCRIPT
A three-dimensional object with dimensions of height,
width, and depth.
Just like shapes, forms are also divided into the same 2
categories: organic and geometric.
FORM
GeometricMade by man, precise and described using mathematical
OrganicGenerally made by nature
and are irregular and uneven
Types of Shape
When an artist works in three
dimensions, he or she is working
with form.
CERAMIC vocab:
Fine grain, sticky dirt that is pliable when wet, brittle
when dry and hard when heated
A special oven that can reach very high temperatures,
used to fire clay
CLAY:
KILN:
WEDGING:
MODELING:
TOOLS
SCORE:
SLIP:
FIRE:
A way of improving the workability of the clay by making it
consistent and even in texture while eliminating the air
bubbles.
Term used when turning on a kiln to get up to
temperature to change clay particles into a ceramic form.

Clay Stages
SLIP = LIQUID
A creamy liquid made with clay and water
used to join pieces of clay together.
PLASTIC = MALLEABLE
The stage of clay where it is still moldable. It
can be shaped or manipulated without
tearing or breaking.
LEATHERHARD = STRONG/DAMP/COLD
Clay had started to dry, but, it still has some
moisture. Leatherhard clay can still be carved
into or joined to other pieces. CAN’T
MANIPULATE!
BONE-DRY = FRAGILE
Stage of drying when moisture in the clay has
COMPLETELY evaporated. The clay is at room
temperature.
Clay
that
hasn’t
been
fired
Clay Stages...cont.
BISQUE = STURDY/POROUS
Ceramic ware that has gone through the
first stage of firing at a relatively low
temperature and still maintains its porous
state.
GLAZE FIRED = FINISHED/NON-
POROUS
The firing during which glaze materials
melt and form a coating on the clay
body surface.
Ten Golden Rules of Clay!
1. Clay must be thoroughly covered up with a plastic bag to
keep it from drying out. This applies to works in progress
and moist clay.
2. Clay dust can be harmful if you are exposed to it for long
periods of time, so keep your area clean, clay scraps off
the floor and clean with water and a rag.
3. Clay can be NO THICKER than your thumb. RULE OF
THUMB!
4. In order for clay to stick together it MUST be scored and
slipped together while the clay is moist or leatherhard.
5. Wedge clay to remove air bubbles, to achieve uniform
consistency and to line up the clay particles.
Ten Golden Rules of Clay!
6. Trapped air can cause clay to explode during the firing process. So hollow out sculptural forms or thick areas and put needle holes from the bottom so air can escape. Exploding pieces in the kiln can damage other pieces near it.
7. WRITE YOUR NAME OR INITIALS AND DATEYOUR PIECE ON THE BOTTOM OF IT.
8. Always handle your project with two hands at all times. In other words, BE CAREFUL! Lift by the body of the piece and support the weight with your other hand.
9. NEVER HANDLE ANOTHER STUDENT’S PIECE NO MATTER WHAT!
10.DO NOT THROW CLAY EVER! This will result in removal from the clay project and an automatic F for the project!
• A pottery making technique where you make a
pot by pressing your thumb in the center of a
ball, rotating the ball while pinching up the sides.

PINCH POT CONSTRUCTION
1ST
2ND
3RD
Create a ball of clay by rolling it in
your hands, begin by pushing an
indention in the center of the clay with
your thumb.
Turn the piece as you pinch up the side
walls. Try to keep an even thickness as
you rotate and pinch the clay.
Continue to turn the piece as you pinch
up the side walls. Try to keep an even
thickness as you rotate and pinch the
clay. Smooth the outside of the pot with
water if necessary.
• Long rope-like cords of clay used to create a
form
– Using 2 hands applying even pressure, you
will roll out the clay into long rope-like cords
