WHAT IS CLAY?

Clay is a naturally occurring mineral material, highly plastic when damp,

chemically inert, and refractory when fired. Alumina + Silica + Water

Al2O3 2SiO2 2H2O

PLASTICITY of clay is due to the shape and size of its particles,chemical/electrical attraction of particles,

and the presence of organic material.

CLAY BODIESCLAY BODIES

A clay body is a formulation of clays and other ingredients designed for particular properties such as color, texture, maturing temperature,

plasticity, shrinkage, and drying and firing properties.

Additions to clay bodies might include fluxes,sand, grog or combustible fillers (like sawdust) to “open” or lighten

the clay body, bentonite or ball clay for plasticity, iron oxide for color.
