Sculptural Pottery vs. Functional Pottery
Functional pottery serves a purpose: a mug holds coffee, a bowl holds soup. Sculptural pottery exists to be seen, touched, and experienced. The freedom is exhilarating but also challenging — without the constraints of function, you must find your own direction. The best ceramic sculptures often blur the line, taking familiar functional forms and pushing them into expressive territory. A teapot that could never pour, a vessel that could never hold water, a plate that hangs on the wall.
Stephen Jepson always encouraged his UCF students to explore sculpture alongside functional work. He believes that sculptural thinking — composition, surface, negative space, gesture — makes functional pottery better too. The skills transfer both ways.
Core Sculpture Techniques
Coil Building for Sculpture
Coil building is the oldest pottery technique and perhaps the most versatile for sculpture. Roll ropes of clay and stack them, blending the coils together on the inside while leaving them visible on the outside for texture — or smooth both surfaces for a seamless form. Coil building allows you to create any shape: tall, wide, narrow, asymmetrical, organic. The walls can curve in any direction. There is no size limit — ancient cultures built storage vessels taller than a person using coils.
For sculpture, coil building lets you work slowly and thoughtfully. You can build a section, let it stiffen, and add more the next day. This controlled approach is essential for large or complex forms that would collapse under their own weight if built too quickly.
Slab Construction
Roll clay flat with a rolling pin or slab roller, then cut shapes and assemble them like a three-dimensional puzzle. Slab building is excellent for angular, geometric, architectural forms. Score and slip every joint. Reinforce inside corners with small coils pressed into the seam. Slabs can be draped over forms for organic curves or bent into crisp folds for modern aesthetics.
One powerful technique is to roll slabs with texture — press fabric, leaves, wire mesh, or carved stamps into the clay before cutting. The texture becomes part of the surface design when the slab is assembled into a sculpture.
Solid Modeling
For small sculptures, you can work from a solid block of clay, carving and shaping like a traditional sculptor. The critical rule: the finished piece must be hollow or no thicker than about one inch at any point. Thick solid clay explodes in the kiln because trapped moisture expands into steam. For solid-modeled work, either hollow out the piece at leather-hard stage or build it hollow from the start using pinch and coil methods.
Wheel-Thrown and Altered
Throw basic forms on the wheel — cylinders, bowls, closed shapes — and then cut, bend, combine, and alter them into sculpture while leather-hard. This technique is fast and produces forms with the smooth surfaces and even walls of wheel work combined with the expressiveness of hand manipulation. Cut a cylinder in half and reassemble at an angle. Join two thrown forms together. Paddle the sides of a round form into flat planes.
Surface Techniques for Sculpture
Texture and Carving
Sculpture invites bold surface treatment. Carve deeply into leather-hard clay with loop tools and wire ends. Press found objects into soft clay — screws, bolts, bark, shells, fabric. Build up texture by applying small clay pieces — pellets, strips, stamps — to the surface. The interplay of light and shadow on a textured surface gives sculpture its visual depth.
Terra Sigillata
A refined clay slip that fires to a soft sheen without glaze. Apply thin layers to bone-dry ware and burnish with a soft cloth or smooth stone. Terra sigillata is especially beautiful on sculpture because it enhances surface detail without filling carved lines the way thick glaze does. Fire to a low temperature to preserve the sheen.
Mixed Media
After firing, sculpture can incorporate non-clay materials: wood, metal, fiber, found objects. A ceramic form mounted on a steel armature. Woven cord threaded through holes in fired clay. Driftwood cradling a burnished clay sphere. Mixed media expands the visual and conceptual range of ceramic sculpture beyond what clay alone can achieve.
Firing Sculpture
Large sculptures need slow firing — especially in the early stages when remaining moisture turns to steam. Program a slow ramp up to 250 degrees Fahrenheit and hold for an hour or more. This candling period drives out physical water without cracking. Sculptures with varying wall thickness are particularly vulnerable — thin sections heat faster than thick ones, creating stress. Even drying before firing is just as important as even construction.
