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.

Even the thickness of the clay wall
Smooth the surface of the wall without the gap and wrinkle  







 Cut it Open/ open apart


From side to side 






From the middle




One combined with 2 pinch pots and one extra pinch pot





 Build a  base for better structure or function
