Sculpture is three-dimensional artwork created by shaping or combining hard and/or plastic material, sound, and/or text and or light, commonly stone (either rock or marble), metal, glass, or wood. Some sculptures are created directly by finding or carving; others are assembled, built together and fired, welded, molded, or cast. Sculptures are often painted.
Because sculpture involves the use of materials that can be molded or modulated, it is considered one of the plastic arts. See: The Free Dictionary
