Ceramics Vocab
| Term | Definition |
|---|---|
| Hand Building | This term refers to one of several techniques of building pots using only the hands and simple tools rather than the potter's wheel. The term used for creating pottery using the potter's wheel is "throwing" |
| Pinch | a method of shaping clay by inserting the thumb of one hand into the clay and lightly pinching with the thumb and fingers while slowly rotating the ball in the palm of the other hand. Pots made in this manner are called "pinch pots" |
| Coil | This is the technique of building ceramic forms by rolling out coils, or ropes, of clay and joining them together with the fingers or a tool. |
| Molding | In this technique, flat slabs of clay are pressed into molds in order to create various shapes or forms. |
| Slip | Liquid clay. The easiest way to make slip is to gradually sift or spoon dry, powder clay into a small cup of water. Stir well as you add because it will tend to thicken up after it sits for a minute or two. |
| Score and Slip | a method of joining two pieces of clay together. First, score the clay. Then you slip it; that is you wet the surface with some slip, using it like glue. |
| Stages of Dryness | When speaking of clay, we refer to three basic stages of dryness: wet, leather hard, and bone dry. |
| Sgraffito | a decorating technique developed centuries ago. In its simplest embodiment, leather-hard clay is coated wit an engobe or slip of contrasting color and then a pattern or picture is added by carving through or scraping off the slip to reveal the clay. |
| Wax resist | In the decorative technique, patterns or designs are created by brushing a wax medium over an area of clay, slip, or glaze to resist the final glaze application when wax is dry. |
| Slip Trailing | Another decoration method. Slip is applied to the greenware through a tube or nozzle, much like icing a cake. |
| Stamping | This is the technique of pressing forms into the clay to get decorative effects |
| Mille Fiore | This refers to a method of creating designs by folding different colored clays together into "rods" or bars, then slicing them as if you were slicing rolled cookies. This duplicates a design over and over for each slice. |
| Firing | The process of heating the pottery to a specific temperature in order to bring about a particular change in the clay or the surface. |
| Bisque | A ceramic ware that has been fired once without glaze. |
| Greenware | A ceramic ware that has not been fired. |
| Glaze | A glass-like surface coating for ceramics that is used to decorate and seal the pores of the fired clay. |
| Reduction | A kiln firing in which there is insufficient oxygen to consume the free carbon emanating from the heated glaze and clay, resulting in the formation of carbon monoxide. |
| Oxidation | A kiln firing with a full supply of oxygen (as opposed to a reduction firing.) Electric kilns are this type. |
| Raku | Raku is a method of firing pottery that takes a ceramic piece in its raw state, greenware, and quickly takes the temperature up to almost 2000 degrees. |
| Mouth | The opening at the top of a vase |
| Neck | The narrower part that leads from the body of the vase to the mouth. |
| Body | this is the main part of the vase. It is usually the largest part. |
| Foot | This is the part of the vase that meets the floor. |
