Banding Wheels are revolving wheelheads which sits on a pedestal base. It is turned by hand and used for finishing or decorating pottery.

Bisque is pottery which has been fired once, without glaze, to a temperature just before vitrification.

Bisque Fire is the first firing, without glaze. Slips can be used in a bisque firing.

Bone Dry means it's completely air dried.

Centering is a technique to move the clay in to a symmetrical rotating axis in the middle of a wheel head so you can throw it.

Chucks are pieces used to aid the potter in trimming. A chuck is a form that can hold a pot upside-down above the wheel head while the potter trims it. Chucks are thrown and bisque fired clay cylinders which are open on both sides.

Clay bodies are mixtures of different types of clays and minerals for a specific ceramic purpose.

Coils are pieces of clay rolled like a rope, used in making pottery.

Compressing is pushing the clay down and together, forcing the particles of clay closer.

Crazing is the cracking of a glaze on a fired pot. It is the result of the glaze shrinking more than the clay body in cooling process.

Crawling is a bare spot (from the shrinking of a glaze) on a finished piece where oil or grease prevents the glaze from adhering to pottery.

Damper is a slab of refractory clay that is used to close or partially close the flue of a kiln.

Dry-Foot is a technique of keeping the foot or bottom of a pot free from glaze by waxing or removing the glaze.

Earthenware is a low fired clay body. Glazed pottery is fired to a temperature of 1,830 - 2,010 degrees Fahrenheit. Available in red or also white.

Englobe is colored clay slip used to decorate greenwear or leather hard pieces before bisque firing. Clay and oxide and water.

Firing is heating a clay object in a kiln to a specific temperature.

Firebrick is an insulation brick used to hold the heat in the kiln and withstand high temperatures.

Firing Range is the range of temperature at which a clay becomes mature or a glaze melts.

Flux is a melting agent causing silica to change into a glaze.

Foot is the base of a ceramic form.

Frit is a glaze material which is derived from flux and silica which are melted together and reground into a fine powder.

Glaze is a thin coating of glass, an impervious silicate coating, which is developed in clay ware by the fusion under heat of inorganic materials.

Glaze firing is the final firing, with glaze.

Gloss Glaze is a shiny reflective gloss.

Greenware is unfired pottery, ready to be bisque fired.

Kilns are furnaces of refractory clay bricks for firing pottery and for fusing glass.

Kiln Furniture are refractory posts and shelves used for stacking pottery in the kiln for firing.

Kiln Wash is a mixture of Kaolin, flint and water.. It is painted on one side of the kiln shelves to separate any glaze drips from the shelf.

Leather Hard is a stage of the clay between plastic and bone dry. Clay is still damp enough to join it to other pieces using slip. For example, this is the stage handles are applied to klah mugs.

Matt Glaze - A dull glaze surface, not very reflective when fired. It needs a slow cooling period or it may turn shiny.

Molds are plaster shapes designed to pour slip cast into and let dry so the shape comes out as an exact replica of the mold.

Maturing Point is the temperature at which the clay becomes hard and durable.

Opaque Glaze is non-transparent glaze, it covers the clay or glaze below it.

Oxidation is firing with a full supply of oxygen. This shows brighter colors.

Pinching is when you manipulate clay with you fingers in your palm to a hollow shape. Pinch pots are a popular beginners project.

Plasticity is the quality of clay which allows it to be manipulated into different shapes without cracking or breaking.

Rotating wheel head used to sit at and make pottery forms.

Pugging is a term used to describe mixing.

Reduction is firing with reduced oxygen in the kiln.

Ribs are a metal or wooden tool used to facilitate wheel throwing of pottery forms.

Satin Glaze is a glaze with medium reflectance, between matt and gloss.

Slab are pressed or rolled flat sections of clay used in hand building.

Soaking clay is maintaining a low steady heat in the early stages of firing to achieve a uniform temperature throughout the kiln.

Stacking is when you load a kiln to hold the maximum number of pieces. Overloading can lead to not-so-much wanted consequences.

Stain is oxide and water, used as a colorant for bisque wear.

Transparent Glaze transmits light clearly so that the original color of the clay after it's been 'cooked' can be seen.

Throwing is creating ceramic shapes on the potters wheel, aka, nifty little designs.

Vitrification is the firing of pottery to the point of glossification. This will make it shiny and pretty.

Wedging is a method of kneading clay to make itthe same through out by cutting and rolling it.
