Sculpture

In sculpture, surfaces are the primary elements through which observers infer internal structure and expressive intent. Sculptors manipulate these surfaces to convey specific physical and emotional qualities:1
- Softness and Fullness: Double-curved convex surfaces are used to suggest fullness, containment, and the outward pressure of internal forces.1
- Tension: Surfaces that combine both convex and concave curvatures suggest the operation of internal pressures balanced against a receptivity to external influences, often associated with growth and expansion.1
- Movement and External Forces: Concave surfaces represent the encroachment of space into the mass of the sculpture, suggesting the action of external forces or indicating collapse and erosion. Additionally, sculptors may use "negative volumes"—carefully shaped holes and cavities—to create movement through space.1
Beyond surface curvature, artists can enhance these effects by manipulating light and shadow. By creating deep, shadow-catching hollows or prominent, highlighted ridges, sculptors can emphasize specific forms or create a sense of mystery and obscurity. Furthermore, the choice of material and the method of handling—such as preserving the direct, fluent marks of modeling in clay or wax—can further communicate the sculptor’s intent and the energy behind the work.12
