What is Clay?

Ball clay is a kaolinitic sedimentary clay that has been chemically altered and mixed with sand, organic materials, and other constituents. The ideal kaolin mineral structure has been altered by substitutions of other elements for the aluminium and silicon atoms in the kaolin crystals. The imbalance created by these substitutions produces a desirable “plasticity” characteristic when ball clay is used with water to form ceramic items.
