| description | Three-dimensional art and sculptural thinking for art education. Covers additive and subtractive sculptural processes, armature construction, modeling in clay, carving principles, casting and moldmaking, assemblage and found-object sculpture, installation art as expanded sculpture, and the conceptual transition from pictorial to spatial thinking. Use when working with three-dimensional media, analyzing sculptural form, understanding spatial composition, or investigating the relationship between sculpture and site. |

Sculpture & 3D Art
Sculpture is the art of thinking in three dimensions. Where drawing and painting represent space on a flat surface, sculpture occupies space directly -- it has mass, casts shadows, changes as the viewer moves around it, and interacts with its environment. This skill covers the fundamental processes of sculptural making, the cognitive shift from pictorial to spatial reasoning, and the expanded field of three-dimensional art that includes installation, assemblage, and site-specific work.

Sculptural Processes
| # | Process | Direction | Materials | Key principle |
|---|
| 1 | Modeling | Additive | Clay, wax, plaster | Build up form by adding material |
| 2 | Carving | Subtractive | Stone, wood, plaster block | Remove material to reveal form |
| 3 | Casting | Reproductive | Bronze, resin, plaster, concrete | Create a mold, then fill it to reproduce form |
| 4 | Assemblage | Constructive | Found objects, metal, wood, mixed media | Join separate elements into a unified whole |
| 5 | Installation | Spatial | Any and all materials | Create an environment or experience, not just an object |
Process 1 -- Modeling (Additive)
Pattern: Begin with nothing (or an armature) and build form by progressively adding material -- pinching, coiling, slab-building, or direct hand-modeling.
Materials: Water-based clay (earthenware, stoneware), oil-based clay (plasticine, Chavant), wax, polymer clay, papier-mache.
Armature construction: For figures or forms that extend beyond the structural capacity of the clay alone, build an internal skeleton from wire, pipe, wood, or aluminum foil. The armature carries the weight; the clay provides the surface. Armatures are essential for life-size or larger figurative work.
Key principle: Modeling is forgiving. Material can be added, removed, and repositioned throughout the process. This makes it the best process for learning sculptural thinking, because mistakes are reversible. The cognitive habit to develop is continuous rotation -- turning the work every few minutes to evaluate it from all angles.
