1.
A support or frame used when sculpturing clay; usually removed before firing.
2.
A revolving wheel head which sits on a pedestal base. It is turned by hand and used for finishing or decorating pottery.
3.
A base for throwing, hand – building, or drying; usually made of plastic, pressboard, plywood, or plaster.
4.
Polishing the surface of leather-hard pot to compact it and produce and maintain a sheen at low firing temperatures. Objects such as a smooth stone or back of a spoon are good burnishing tools.
5.
A category of green, gray, or blue-gray glazes for stoneware and porcelain; developed in China and Korea.
6.
The process of applying pressure to a lump of clay on a spinning wheel head to position it for even rotation.
7.
The tendency of matter to “flee from the center” when spun.
8.
Squeezing the upper part of a thrown from as it rotates on the wheel, in order to decrease the size of its diameter.
9.
Part of the centering process; raising clay to form a cone as it spins on the wheel head.
10.
The result of successfully centering clay on the wheel. An opened dome is necessary to begin throwing vessels, pots, and plates.
11.
A wheel powered by the potter’s foot rather than by electricity.
12.
The rim opening of a pot.
13.
A support that holds a clay slab in a certain shape until it stiffens.
14.
A way of improving the workability of clay by reforming the mixture to make it homogeneous and even in texture while eliminating air bubbles.
15.
Changes in a clay form usually resulting from uneven thickness of the walls, uneven drying, or stresses during firing caused by poor support or uneven heat.
16.
A container made from fireproof material that protects ware from combustion gases during firing. It is also used to hold ware and fuming materials for separate reduction during firing.
17.
The part of a vessel between lip and shoulder.
18.
A pattern used to shape the profile of a piece.
19.
Heating pottery or clay sculpture to a temperature high enough to render it hard and durable.
20.
A mixture of Kaolin, flint and water used to coat kiln shelves to protect them during firing.
21.
The process of shaping plastic clay on the potter’s wheel.
22.
When clay fuses and turns to a fluid glasslike substance during the firing.
23.
A device, such as rubber syringe or tube, used to apply lines of slip on clay as decoration.
24.
A firing in there is insufficient air in the kiln for complete combustion. The metal oxides in the clay body and glaze release oxygen because there is not enough present in the atmosphere. This changes the color of the clay body and glaze.
25.
The process of shaping clay by forcing through a die.
