Clay Terminology

Kiln: an oven that heats to very high temperature and is made to fire clay 



3 techniques: pinch, coil, slab 

Combined Pinch Pots


Coil

Slab

Wet clay: wet clay that is soft and easy to shape

Leather hard: clay that is partially dry and can be carved



Greenware: clay that is finished, dry( bone-dry clay is one of the most fragile states), and ready to be fired

Firing: the process of heating clay in a kiln

Bisque ware: clay that has been fired once

Underglaze: underglazes are formulated to be pigmented colored slips. The underglaze is it can be painted on either greenware or bisque-fired clay for the desired design. 

Gloss Glaze( Over glaze, Clear glaze): a clear overglaze will seal the piece and make it non-porous. Non-porous surfaces are smooth and sealed so liquid and air cannot move through them.
