Coil method
On of the oldest ways of forming pottery. Long strands of clay which are laid on top of each other and joined though blending coil to coil. Coli pieces can be almost any shape and any size.
Cone Temperature
Is the mixture of time and temperature at which the cone will bend to show the kilns temperature on the shelf.
Slab
A flattened out pieces 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 sames 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.
