Ceramics: The art of making things from clay.
of forming clay
Stages of clay
Greenware: Unfired pottery.
Fire: The term used for baking work in the kiln.
Leather hard: Clay that is dry enough to be joined or carved without distortion. Clay in this state is hard to bend but soft enough to be carved.
Bone dry: Refers to clay that is ready to be fired. All of the moisture is gone from the clay. Clay is VERY FRAGILE at this stage.
Bisque: Fired pottery that is unglazed.
Bisque fire: The first firing of the clay, done before glazing and glaze firing.
Glaze fire: Firing to a temperature at which glaze melts to form a glasslike surface.
Glaze: A thin coating of special glass, used as a decoration and to seal clay surfaces.
Handbuilding: One of the oldest craft techniques in which objects are constructed entirely by hand.
Throwing: Forming clay on the potters wheel.
Coil technique: Handbuilding technique in which the object is built up with rope like pieces of clay, one on top of another.
Slab technique: Handbuilding technique in which flat pieces of clay are joined together. (Clay is flattened or thinned with a rolling pin).
Pinch technique: Handbuilding technique in which a ball of clay is pinched from the center out with the thumbs to create a bowl shape.
Bat: A plastic form attached to the potters wheel before throwing so your pieces can be removed without distortion.
Score and Slip
Scoring: Roughing up the surface of the clay for joining pieces.
Slip: A liquid form of clay used as a glue to join pieces. Can also be used for decoration.
Kiln: The large brick oven used for firing ceramic pieces.
Cone: A type of thermometer placed in the kiln to indicate when firing is complete. The cone is made of glaze materials and will bend to indicate the end of a firing. (We fire between Cone 04 and 06 which is approx. 1800
Stage of clay that can be formed into various shapes using either a handbuilding or wheelthrowing technique.
Wedging: A process of kneading the clay in a spiral motion forcing out air bubbles from the clay in order to obtain a uniform consistency. (trapped air will cause clay to explode in the kiln).
Texture: High or low patterns created by pressing or carving designs into the clay.
Incising: Carving designs into a flat surface.
Slip and score
The proces of making a semetrical lump of clay that is precisely in the center of the wheel
The process of raising the walls of the form.
The process of taking away material to create a foot or design.
Foot: A raised peice of clay that allows the form to stand away from the surface it is placed on
