Shape is important in pottery because it sets the mood for the finished look. A vase that is too flat would not look quite right. A plate with sides that are too high would look more like a bowl. Once shape has been correctly mastered, a pottery piece is enhanced by decoration. This usually takes the form of stains, glazes or paints. These colorants are brushed onto the surface of a bisque piece. They can also be added after a glaze has been fired onto the piece. Paints, stains and glazes add color and focus to finished pottery.
