BUILDING METHODS

Shaping a clay bowl by squeezing it between the thumb and fingers.

PINCH-

COIL-

Using clay ropes to build a vessel.

Using rolled-out flat pieces of clay to build a structure.

SLAB-

Forming clay vessels on a large wheel that turns.

WHEEL THROWN-

ARMATURE:

A skeletal support for sculpture- often wire.

Kneading the clay to remove air bubbles.

WEDGING:

A piece of clay added to another piece of clay. (ie-an arm or a leg)

It’s important that attachments aren’t too thin.

Reinforce attachments by attaching them to another piece of clay.

ATTACHMENT:

“Scratching” the surface of a piece of clay before it is added to another.

SCORING:

Very watery clay mixture that is the consistency of sour cream.

SLIP:

A large oven used to fire (harden) clay. The kiln heats to over 2000 degrees.

KILN:

1. PLASTIC2. LEATHERHARD3. BONE DRY4. BISQUEWARE5. GLAZEWARE

CLAY STAGES:

Wet, workable clay.

1. PLASTIC:

Clay that is partially dry. No new clay can be added to clay at this stage (it will crack off).

2. LEATHER HARD:

Clay that is completely dry and ready to be fired.MOST BREAKABLE STAGE!!!

3. BONE DRY:

Clay that has been fired once.

4. BISQUEWARE:

Clay that has been fired TWICE after glaze was applied.

5. GLAZEWARE:

Clay should be 3/8” thick (about a finger width).

If clay is too thin: it will break.

If clay is too thick: it will explode (from either trapped air or water).
