To be awesome.
Ceramic
Havingto do with clay or class or the making of objects from clay or class
Slip
clay that has been watered down ; acts as glue in slip/score technique. slip a fine, liquid form of clay applied to the surface of vessel prior to firing . Slip fills in pores and gives uniform
Score
to draw or make lines into clay
Wedging
Is the process og kneading the clay so as to remove air pockets and create uniform consistency of clay
Coil Method
One of the oldest ways of forming pottery . Long strands of clay which are laid on top of each otyher and joined throught blending coil to coil . coil piecescxcan ce almost any shape and any size
Stoneware
high-fire clay . Stoneware is waterproof even with Glaze; the resulting ware is sturdier than earthenware
Slab
A flattened out piece of clay ; you may usea rolling pin or slab roller to achieve a slab of clay. Clay slabs are cut to shape and joined together using scoring and wet clay called slip . Slab can be draped over or into forms , rolled around cylinders or built-up into geometric forms. Large forms are difficult because of stresses on the seams and because the slab naturally sags.
some potterget around this by working fibers into the clay body . the fibers Burn out durng the firing , leaving a network of tiny holes
Bone Dry
clay that is completely dried but not yet fired
Greenware
a term used to describe unfired clay objects in general
Bisque Ware
bisque ware that has been glaze then fired
Glaze Ware
bisque ware that has been glazed then fired
Fettling Knife
Is a specail knife-like tool with a fairly flexible blade for cutting into moist and leather-hard clay
Loop Tool

Slip/Score Technique
Method used in hand building to connect two pieces of clay together
Incising

Kiln
A furnace designed specifically for heating clay to the temperatures necessary to make it permanently hard and Stone Like . Kilns can be electric , natural gas , wood ,coal , fuel oil or propane . Materials used to heat the kiln can a fact the work : would ash can build up on the surface of a piece and form a glaze at a high temperatures. Some Potters introduce chemicals into the kiln to influence the effect of the firing. Famed ceramist Beatrice Wood Achieved a Luster Effect by throwing moth balls in the kiln .
Element
The Heating coils of an electric kiln .( Tired or burned-out elements refer to Elements which carry too little or no electrical currents for producing heat
Foot
The bottom of a piece that Rest upon the surface (May be wheel thrown or hand-built) there are two kinds: raised and flush
Firing
Clay is hardened by heating to a high temperature ,fusing The Clay particles . Primitive pottery is usually fired on the ground or in pits with whatever flammable material is available . Kilns allow more efficient use of materials and more control over the atmosphere during a firing . Firing has two basic atmospheres. Oxidation and Reduction, these two atmospheres will affect the color of the final piece .
Glaze
Glass-Forming chemicals , usually with colorants added , that applied in liquid form to bisque ware and fired in a kiln, forn a pleasing , usually glossly coating to the surface of the clay . Glazw can be colored , opaque ,translucent or matte
