What does assemblage refer to in sculpture?

Assemblage refers to a three-dimensional composition of unified objects, which is the hallmark of this sculptural technique. In assemblage art, artists create sculptures by combining a variety of materials and found objects into a cohesive work. This approach encourages innovation and creativity, allowing artists to explore themes and concepts in unique ways. By merging disparate elements, assemblage can challenge traditional notions of sculpture and encourage viewers to experience art in a more dynamic and non-linear fashion.

The other options do not accurately capture the essence of assemblage. A traditional sculptural technique and methods like casting in bronze or marble carving pertain to established forms of sculpting with specific materials and techniques, contrasting the more eclectic and experimental nature of assemblage.
