Companies that specialize in decorative pieces work to achieve a goal of national distribution through retailers. If each piece were hand-crafted, they would not be able to achieve their goal. They use forms to make ceramic pieces and add decorative touches.
By using these methods, they can produce a large amount of work in a shorter time. It allows them to have many pieces available for commercial sale. This does not necessarily take away from the beauty of any decorative item, but it keeps it from being completely unique. It also makes them less expensive and more affordable as an art object in many households.
