Clays exhibit plasticity when mixed with water in certain proportions. When dry, clay becomes firm and when fired in a kiln, permanent physical and chemical changes occur. These reactions, among other changes, cause the clay to be converted into a ceramic material.

A white glaze background will be spread on the surface of the object to render it impermeable and make it possible to decorate. The glazing can be followed through with a paintbrush, sprayed, or following an antique technique, for immersion; this consists of immerging objects in a tub of white paint.

To decorate with a brush is safely one of the most various methods and used for the decoration of an object, both underglaze and on enamel. The colors well blended be applied in like manner to watercolor, proceeding from the lightest to the darkest.
