Type of Clay Flashcards
Slip
clay that has been watered down; acts as glue in slip/score technique. Slip is a fine, liquid form of clay applied to the surface of a vessel prior to firing. Slip fills in pores and gives uniform color.
Slab
a flattened out piece of clay; you may use a 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. Slabs 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 potters get around this by working fibers into the clay body. The fibers burn out during the firing, leaving a network of tiny holes.
